How to change the oil in the “Neva” walk-behind tractor?

check, gearbox, walk-behind, tractor

Any technical equipment has a complex design, where absolutely everything is interdependent. If you value your own equipment, dream that it will work as long as possible, then you must not only look after it, but also buy good spare parts, fuel and oils. But if you start using low-quality oil, then in the future you will encounter a number of complications and the technique may need repairs. In this note, we will describe which oils (lubricants) are suitable for a particular unit and methods for replacing oils in a walk-behind tractor.

How to replace the lubricant in the gearbox?

  • Before you start filling with new fluid, you need to drain the old.
  • Place the cultivator on a raised platform. This will make it easier for you to drain the lubricant.
  • You will find 2 plugs on the gearbox. One of the plugs is designed for draining, it is located at the bottom of the unit. The other closes the filler neck. The filler plug is turned out first.
  • Take any reservoir and place it directly under the oil drain plug.
  • Unscrew the oil drain plug carefully. The transmission oil will begin to drain into the container. Wait until absolutely all the oil has drained, after which you can screw the plug back into place. Tighten it to the limit with the spanner.
  • Insert a funnel into the filler neck. Take the appropriate lubricant.
  • Fill it up to the required level. Then replace the plug. Now you need to find out the level of lubricant. Tighten the plug with the dipstick all the way. Then unscrew it again and inspect.
  • If there is lubricant at the tip of the probe, do not add any more.

The procedure for changing the transmission lubricant will depend on the modification of the walk-behind tractor. But basically, replacement is done after every 100 hours of unit operation. In some episodes, more frequent replacement may be necessary: ​​after every 50 hours. If the cultivator is new, then the initial replacement of the lubricant after running in the walk-behind tractor must be performed after 25-50 hours.

A systematic change of transmission oil is necessary not only because the manufacturer advises it, but also for a number of other circumstances. During the operation of the cultivator, foreign steel particles are formed in the lubricant. They are formed due to the friction of the components of the cultivator, which are gradually crushed. Ultimately, the oil becomes thicker, which leads to unstable operation of the walk-behind tractor. In some cases, the gearbox may fail. Filled with fresh lubricant prevents such unpleasant events and eliminates repairs. Replacing a lubricant is several times cheaper than purchasing and installing a new gearbox.

If you want your technical equipment to function for a long time and correctly, do not ignore the timely oil change. How to maintain and clean the oil filter of a motor-cultivator Maintenance of the air filters of the motor-block motor must be carried out according to the maintenance intervals indicated by the manufacturer or as needed if the technical equipment is used in conditions of high dustiness. It is advisable to inspect the condition of the air filter every 5–8 hours of the operation of the walk-behind tractor. After 20-30 hours of activity, the air filter needs to be cleaned (if it is damaged, change it).

Do I need to fill and change the oil in the air filter of the motor cultivator?

In the vast majority of situations, it is enough just to slightly saturate the air filter sponge with machine oil. However, the air filters of certain modifications of motoblocks are in an oil bath. in such a situation, lubricant should be added to the level marked on the oil bath.

What type of oil should be poured into the motor cultivator

There are many disputes about what kind of oil should be poured into the engine of a home cultivator (walk-behind tractor). Someone is sure that his views are correct, others deny them, but the only thing that can resolve such discussions is the manual for the unit, created by the manufacturer of the product. Any manufacturer in it prescribes a specific volume of oil to be poured, a method for measuring this volume, including the type of oil that can be used.

What all their positions have in common is that the lubricant should be designed specifically for the engine. Two types of oils can be distinguished. oils for 2-stroke engines and oils for 4-stroke engines. Both the one and the other samples are used for motor cultivators in accordance with which particular motor is mounted in the model. Most of the cultivators are equipped with 4-stroke motors, however, in order to establish the type of motor, you need to familiarize yourself with the manufacturer’s markings.

Both types of oils are divided into 2 types according to their structure. This aspect makes it possible to distinguish synthetic and semi-synthetic oils, or, as they are also called, mineral oils. There is a judgment that synthetics are more versatile and can be used regularly, but this is wrong.

The use of oils is distributed according to the seasonality of the operation of the cultivator. So, some modifications can be used in the winter season. Due to the thickening of natural elements that are susceptible to a drop in temperature, semi-synthetic lubricants cannot, along with mineral ones, be used in winter. However, the same oils are safely used in the summer season and thoroughly protect the equipment.

Thus, the lubricant is used not only as a lubricant for the components of the engine, but also serves as a medium that excellently restrains the soot produced during fuel combustion and metal particles that arise during component wear. It is for this reason that the lion’s share of oils has a thick, viscous structure. To find out what kind of oil is needed for your particular technique, carefully study the operating manual of the cultivator. The manufacturer specifies what kind of oil must be poured into the motor or gearbox, therefore it is recommended to follow these tips.

For example, for the Neva MB2 motor cultivator, the manufacturer recommends using TEP-15 transmission oil (-5 C to 35 C) GOST 23652-79, TM-5 (-5 C to 25 C) GOST 17479.2-85 according to SAE90 API GI.2 and SAE90 API GI-5 respectively.

How much grease is required to be poured into the gearbox?

The question of the amount of transmission oil is quite fundamental. Before answering it, you will need to set the lubricant level. This is extremely easy to accomplish. Place the cultivator on a level platform with the wings parallel to it. Take a 70-centimeter wire. It will be used instead of the probe. Bend it into an arc, and then insert it all the way into the filler neck. Then remove back. Inspect the wire carefully: if it is 30 cm stained with grease, then the lubricant level is normal. When there is less than 30 cm of lubricant on it, it must be replenished. If the gearbox is completely dry, then 2 liters of lubricant will be needed.

Oil change in the motor of the “Neva” walk-behind tractor

First of all, you need to find out if you need to change the lubricant? It is possible that its level is still sufficient for the effective functioning of the cultivator. If you still need to change the oil, place the cultivator on a leveled surface and clean the area around the plug (plug) of the dipstick for pouring lubricant into the motor. This plug is located on the bottom end of the motor.

How to set the oil level after changing? Quite simply: by means of a measuring probe (probe). To establish the oil level, wipe the dipstick dry, and then, without twisting the plugs, insert it into the oil filler neck. The oil imprint on the probe can be used to determine which spirit level it is at. On a note! The amount of lubricant in the motor should not overlap the limit mark in any way. If there is an excess of oil in the container, it will pour out. This will increase inappropriate lubricant costs and therefore operating costs.

Before inspecting the oil level, the engine must cool down. A recently functioning motor or gearbox will provide incorrect parameters for the amount of oil, and the level will be significantly higher than it actually is. When the components have cooled down, you can measure the level accurately.

What lubricant to fill in the air filter of the walk-behind tractor?

For such purposes, it is recommended to use the same lubricant that is located in the motor sump. According to the generally recognized standard, machine oil for 4-stroke engines is used in the engine of the walk-behind tractor, as well as in the air filter.

In accordance with the season and ambient temperature, it is allowed to fill the engine with seasonal lubricants of the 5W-30, 10W-30, 15W-40 classes or all-weather engine oils with the most extensive temperature spectrum.

Some simple tips.

  • Never use additives or additives for oil.
  • The lubricant level must be checked when the cultivator is in a level position. You need to wait until the oil is completely drained into the pan.
  • If you decide to completely change the lubricant, drain it with a warm engine.
  • Dispose of the grease in such a way that it does not harm the external environment, in other words, do not pour it onto the ground or throw it in the trash. For this, there are specialized collection points for used motor lubricant.

Transmission oils for filling gasoline and diesel motoblocks

As for the gearbox, gear oils must be used to fill it. For example, semi-synthetic oil ZIC 10W40, designed for gasoline and diesel motoblocks, would be a good choice. API indicator. SM / CF, ACEA. A3 / B3, A3 / B4, C3.

Sold, as a rule, in a 4-liter container,

Another worthy oil is Super T-3 85W-90 from Gazpromneft. Its technical data will be as follows:

  • API indicator. GL-5;
  • viscosity grade. 85W90;
  • temperature indicator of loss of fluidity –.280C;
  • flash point. 2170C;
  • package length. 270 mm;
  • packing width. 130 mm;
  • packing height. 240 mm.

This gear oil is also available in a 4 liter container.,

This is not the whole list of oils that can be poured into the gearbox of the walk-behind tractor. In principle, any person who is familiar with the basic parameters of the oil can independently determine what is needed for his walk-behind tractor.

How to change the oil in the gearbox of the walk-behind tractor

It is recommended to service the gearbox of the Neva walk-behind tractor after every 100 hours of operation or every season, whichever comes first. It is recommended to use only transmission oil for filling into the gearbox.

In order to change the oil in the gearbox of the walk-behind tractor, do the following:

  • Place the single-axle tractor in a vertical position
  • Place a container under the gearbox: not less than 2 liters. for MB Compact, MB1 MultiAGRO, MB2 MultiAGRO, MB23 MultiAGRO; not less than 3 liters. for MB2 CS: GO, MB2, MB23
  • Unscrew the breather plug, clean it from dirt
  • Unscrew the oil drain screw, drain the oil from the gearbox
  • After draining the oil, screw in the oil drain screw with gasket and tighten the screw. Dispose of oil at a waste oil collection point.
  • Fill through the hole for the breather plug with fresh gear oil of the appropriate grade and operating temperature in a volume: 1.15 l. for MB Compact; 1.5 l. for MB1 MultiAGRO, MB2 MultiAGRO, MB23 MultiAGRO; 2.2 l. for MB2 CS: GO, MB2, MB23
  • Screw in breather plug
  • Clean the drive belt tensioning lever shaft and bushing from dirt
  • Lubricate the axle of the drive belt tension lever and bushing with engine oil.
  • Check the operation of the clutch mechanism, adjust the tension of the drive belt
  • Lubricate the clutch cable

The presence of a walk-behind tractor in a personal household can hardly surprise anyone, because this technical device has been known since Soviet times. Thanks to him, it became possible to quickly and efficiently cultivate the soil, which used to take quite a long time, and also took a lot of effort.

However, in order for your single-axle tractor, as they say, to serve you faithfully, regularly plowing the land and performing its other functions, you need to operate it correctly.

In particular, you need to know how much oil to fill in the gearbox of the walk-behind tractor so that it works in optimal mode, and its parts are not erased from the lack of the necessary lubrication.

In principle, all the necessary information, as a rule, is indicated in the operating instructions for a specific model of the walk-behind tractor, where the brands and grades of recommended oils are directly indicated.

However, there are times when a single-axle tractor is purchased by hand, or in another way, but the point is that such walk-behind tractors are supplied mainly without any instructions.

A person may be at a loss, not knowing what kind of oil is poured into the gearbox of the walk-behind tractor, so it will be useful for him to know about its main types, as well as the methods of pouring into a uniaxial tractor.

How much to fill?

Another important point is the amount of oil required. Before answering the question. how much oil needs to be poured into the gearbox of the walk-behind tractor, for example, Crossser, VIKING, Forza, Sadko, Don, Huter, Profi, LANDER, Champion, Carver, you must first check the oil level in the gearbox. To do this, you need to perform certain actions:

  • It is necessary to place the uniaxial tractor on a flat surface so that its wings are strictly parallel to this surface.
  • We take a wire or rod about 70 cm long, which will act as an oil dipstick.
  • We bend the improvised probe into an arc.
  • We insert the resulting probe into the filler hole to the very end, i.e. all the way. After that we take it back out.

If the wire is 30 cm in oil, then this is the optimal indicator, i.e. no need to add oil. If a little less, then it is necessary to top up within the given values.

If the gearbox is dry at all, then at least two liters of transmission oil will be needed.

How to check the oil in the gearbox of the walk-behind tractor

Many people ask themselves how much oil is needed in the gearbox of the walk-behind tractor? What kind of oil to pour into the gearbox of the walk-behind tractor?

Let’s try to answer these questions. According to the representative of the Operational Repair Department (ERO) of the manufacturer, checking the oil level in the gearbox of MB-1 class motoblocks, such as Oka, Neva, Cascade, Luch and the like, is as follows:

  • We install a uniaxial tractor on a flat plane (that is, the wings of the walk-behind tractor should be parallel to the surface, while the gearbox itself is in a working, inclined position)
  • We find a suitable clean wire, a twig 50-70 cm long, or something else that can serve as an impromptu probe.
  • We bend it a little into an arc.
  • We insert the wire-probe into the filler hole of the motoblock gearbox and push it to the end (all the way) along the gearbox body, that is, to the very bottom.
  • We take out the wire.

The wire should be approximately 25-30 cm in oil, in other words, the oil level in the gearbox installed on a single-axle tractor (that is, in the working position) should be approximately at the level of the second bolt from the bottom, the middle bolt (position 10 in the diagram here). which secures the block of sprockets number two of the gearbox (position 9 in the diagram here).

An absolutely dry oil reducer requires 2 liters, when changing the oil 1.5 liters, changing the oil in the walk-behind tractor gearbox is necessary every 50 hours of operation.

Oils recommended by the manufacturer: transmission oils TAD-17I, TAP-15V or others in accordance with GOST 23652-79, mixing of these oils in any proportions is allowed.

Motoblocks “Neva”, as well as motor-cultivators MK100 and MK200 are equipped with mechanical gear-chain gearboxes housed in aluminum cases. The MK70 motor cultivator has a mechanical chain reducer in a steel case. In order for the gearbox to serve for a long time, it is necessary to regularly carry out maintenance of motor vehicles. For diagnostics and troubleshooting, please contact authorized service centers.

How to pour oil into the gearbox of a walk-behind tractor

Before pouring new oil into the gearbox, the old fluid must be drained. It is in this way that the oil in the gearbox of the Salute walk-behind tractor is carried out, the video of which can be found on the Internet, as well as other models of walk-behind tractors.

The algorithm of actions, in this case, will be as follows:

  • a single-axle tractor must be installed on a hill so that the oil can be easily drained from the gearbox.
  • There are two plugs on the gearbox. a drain plug, which is located at the bottom of the gearbox, and a plug that closes the oil filling hole. We first unscrew the filler plug, which is located on top of the walk-behind tractor body (at the checkpoint).
  • We take a sufficiently capacious container (an old bottle of transmission oil is suitable), after which we substitute it under the drain plug of the gearbox.
  • Gently unscrew the drain plug, after which the oil will begin to flow into our container. After waiting for the oil to drain completely, we screw the drain plug back. Then we tighten with a spanner wrench of a suitable diameter until it stops.
  • We insert the funnel into the filling hole. Then we take a suitable gear oil in order to fill the gearbox.
  • After filling the gearbox to the optimal level, we screw the plug back. This plug is equipped with a special dipstick, and its length is about 10 cm. After we have filled in the oil, we need to check its level. To do this, we twist this plug-probe, after which we unscrew it again and check.
  • If the oil is at the tip of this dipstick, then there is no need to top up any more.

As a rule, the oil change procedure must be performed every 100 hours of operation of the walk-behind tractor. In some cases, this procedure must be performed every 50 hours.

In other words, the frequency of oil change depends on the model of the walk-behind tractor, therefore, all the necessary information is in the accompanying documentation for the walk-behind tractor.

How to choose gear oil

When choosing a gear oil for a gearbox, you should be guided by the information specified in the Operator’s Manual for the walk-behind tractor or walk-behind tractor. The use of oil grades that are not included in the recommended list will lead to accelerated wear of gearbox parts.

How to change the oil in the gearbox of a motor cultivator

Maintenance of the gearbox of the Neva MK200 cultivator should be performed every 250 hours of operation. It is better to change the oil in the gearbox immediately after the work of the equipment, since during this period it is easier to drain the oil.

In order to change the oil in the gearbox of the motor cultivator, you should perform the following steps:

  • Place the cultivator in a vertical position
  • Place a container of at least 2 liters under the gearbox
  • Unscrew the breather plug, clean it from dirt
  • Unscrew the oil drain screw, drain the oil from the gearbox
  • After draining the oil, screw in the oil drain screw with gasket and tighten the screw. Dispose of oil at a waste oil collection point.
  • Fill in fresh gear oil of 1.15 liters of the appropriate grade and operating temperature through the hole for the breather plug
  • Screw in the breather plug.

Device

The gearbox is a special device included in the design of any walk-behind tractor. It is this part that is responsible for converting and transmitting the torque that is generated from mechanical transmissions. In fact, the gearbox drives the single-axle tractor, making it work.

The operational life of the entire walk-behind tractor, as well as its normal functioning, will depend on its quality, as well as on the correct lubrication of its components.

For more information on the reducer, see

Depending on the model of the walk-behind tractor, be it Caiman, Patriot Ural, Patriot, Texas, Foreman or any other, the gearboxes may differ in some design features. Conventionally, gearboxes can be divided into several types:

  • Angle gearboxes. Such units are quite effective, they allow you to dock the engine and transmission.
  • Gear reducers. In this case, the gearbox transmission acts as a kind of intermediary between the engine and the wheelbase of the walk-behind tractor.
  • Reducing gears. These units achieve an increase in power indicators, reducing the total number of revolutions. Such gearboxes are the most preferable because they have an air cooling system in their design, which allows them to work at maximum loads.
  • Reverse gearboxes. The main advantage of such gearboxes is the ability to reverse the walk-behind tractor. However, units equipped with this type of gearbox do not show high performance and speeds.

Regardless of which gearbox is used in the construction of the walk-behind tractor, they all consist of almost the same components:

  • shaft;
  • gearbox housing;
  • flange and its fastening;
  • pulley with V-belt transmission (or chain);
  • ball bearing;
  • asterisks;
  • drain plug;
  • steel washer and nut;
  • input shaft.

ADDING ENGINE OIL TO GRAVELY WALK BEHIND TRACTOR AND MAJOR BRUSH HOGGING

These components traditionally form the gear unit itself. How well they are lubricated will affect their performance and service life.

Otherwise, with insufficient lubrication, the parts will wear out a lot, because they come into contact with each other during operation, and the resulting friction negatively affects their surface.

How to disassemble the gearbox of a walk-behind tractor

How much oil to fill in the gearbox of the walk-behind tractor?

Just before filling in new oil, you need to find out how much old material has been filled into the gearbox.

This is done in this order:

BCS 853 WALK-BEHIND TRACTOR GEAR OIL CHANGE

  • First, the uniaxial tractor is placed on a flat surface;
  • Next, a metal wire is taken, at least 70 cm long, and bent into an arc;
  • The resulting product must be pulled through the existing filler hole and push it all the way. As soon as the wire touches the bottom of the gearbox, it should be pulled back.

After that, you need to calculate the length of the wire covered with oil. If the product is about 30 cm in the lubricant, then this is considered the optimal amount of oil that needs to be poured into the gearbox when replacing. If the homemade Schur turned out to be completely dry, then at least 2 liters of the previously unused transmission lubricant will need to be poured into the gearbox of the walk-behind tractor.

Repair of the motoblock gearbox

Complicated technical devices, even with a high quality assembly and components, eventually deteriorate. The gearbox of the walk-behind tractor during intensive operation for a long time requires repair work, otherwise the device will not work correctly.

Replacing the gearbox oil seals

Malfunctioning oil seals can be the cause of gearbox failure. Therefore, repairing the gearbox of the Neva walk-behind tractor may include the following actions:

  • Removing the cutters from the shaft.
  • Cleaning the shaft and cover from dirt and oil residues. Remove all screws from the cover and wash them.
  • Replace the old part with a new one and wipe the entire mechanism dry.
  • Put the cover back in place and fix it with the bolts.

In some cases it is necessary to disassemble the gearbox:

  • Remove the head from the gear shift knob.
  • Remove the bushing and spring from the shaft.
  • Remove all screws and tightening bolts.
  • Using a thin screwdriver or knife, remove the right half of this part.
  • The removed parts must be washed, and the faulty parts must be replaced.
  • The assembly of the gearbox is carried out in the reverse order.

What kind of oil to pour into the gearbox of the walk-behind tractor?

The answer to this question should be known not only to beginners, but also to experienced farmers. The serviceability and service life of the walk-behind tractor gearbox largely depends on the quality and characteristics of the oil.

Before purchasing a lubricant, check the agricultural machine manufacturer’s recommendations. The second important factor is the cost of the oil. You do not need to buy the cheapest lubricants, since in most cases they are not capable of ensuring the normal operation of the mechanism.

Oils for the walk-behind tractor gearbox are divided into several types. Depending on the labeling, the following lubricants are found on the market:

  • SAE. These formulations are used in environments with frequent and severe temperature fluctuations. Thanks to this, oils with this marking can be used almost all year round. When buying such oil, you need to pay attention to the number that is in front of the letter W. The smaller the number, the lower the temperature at which you can fill in the oil;
  • ASEA. oils with this marking are considered almost universal. over, the higher the number in the marking, the more difficult the conditions in which the composition is applied;
  • API. oils with this mark are the most common. They are successfully used for lubrication of all types of gearboxes, and provide long-term operation of mechanisms in the most severe conditions.

All of the listed types of oils for the walk-behind tractor gearbox have their own characteristics. Be sure to study them, and compare the indicators with the recommendations specified in the manual for the walk-behind tractor.

Self-repair of the gearbox

The need to repair a two-shaft gear reducer can arise for various reasons. The procedure for eliminating most of the faults is extremely simple and does not require any special knowledge and skills. In most cases, the product is repaired according to the standard algorithm:

  • The oil is drained, followed by cleaning the unit from contamination.
  • A cast iron or other type of converter is disassembled, each part is inspected for damage, defects, excessive wear.
  • If problematic elements are found, they will need to be replaced with new ones.
  • The device is assembled, the oil is changed.

There are several typical problems that are most common among this kind of technology. First of all, this is a failure in the sliding of the clutch, which is eliminated by replacing the spring and discs. If the device starts to make a significant noise during operation, it is most likely that an immediate oil change, gear mechanism is required.

How to change the oil in the mechanism

One of the most important factors affecting the service life of various types of gearboxes is the presence of oil. It needs to be changed regularly to avoid most problems. To do this, you should follow the simplest instructions:

  • Place the gearbox in working position at a slight slope.
  • Check the oil level. A 25-30 cm probe is normal.
  • Place a single-axle tractor on a raised platform, then unscrew the plug on the body.
  • Wait until the oil is completely drained into the container, fill in a new one using the appropriate hole.

Products of most well-known manufacturers are suitable for operation, as well as any other oil that complies with GOST-17479.

What are the breakdowns?

In most cases, problems in the gearbox of the walk-behind tractor arise due to overloads. Such breakdowns include the bursting of the bushings on the metal chain, which leads to the so-called “slip”. Also, owners of walk-behind tractors very often find broken gearshift bushings. In order to avoid such troubles, experienced owners advise to switch gears only during a complete stop of the equipment, in no case on the move. In addition, star breakage is considered to be a common phenomenon. That is, factory welding is not enough for the star to withstand overload.

It is very easy to “get out” of this annoying situation, you just need to return the star to its original position and grab it by welding much better. Lateral loads lead to wear of the support washer, after which the bushings from the chain are observed to fly off. In addition to the above, it is necessary to periodically check the oil level in the gearbox, as well as replace it.

How to independently repair the gearbox of the walk-behind tractor?

The material presented in this article is especially in demand for people who repair their equipment on their own. Further, the main “subtleties” regarding the repair of the motoblock gearbox will be touched upon. To go directly to the topic of repair, you need to understand the gearbox design. Looking ahead, it is necessary to say: the structure of the gearboxes of modern walk-behind tractors is similar to each other, there are only minor differences in one or another model.

So that the question “How to disassemble the gearbox of a walk-behind tractor?” Does not arise, you need to be familiar with all the details. We list the main parts and components of any modern walk-behind tractor: covers and pulley; bushings with bearings; lever, axle and shift fork; input shaft block with gear; input and output shaft of the motoblock gearbox. Components: washers and seals; right and left semiaxis; clutch and clutch fork; bracket and spring.

How to check the oil in the gearbox of the walk-behind tractor?

Monitor the amount of oil constantly. Otherwise, neglect of technology will lead to fatal consequences. Fresh oil is poured every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to the rapid development of mechanisms and components. Let’s go directly to changing the oil:

  • We install the equipment on a flat area. Find a probe, 70 cm long.
  • The dipstick is bent and pushed into the hole for filling oil until it stops, after which we take out the rod.
  • We observe the oil level, which should be at least 25 cm.In the dry gearbox, add 2 liters of oil, at least 1.5 liters.

The filling oils must be GOST. It makes no sense to use cheap oil, because sooner or later, it will cause breakdowns inside the gearbox of the walk-behind tractor.
