How To Change The Bearing On The Trimmer

Replacing the front wheel bearing

The hub is a very important part of the chassis of any car. In order for it to rotate freely on the axis, a bearing built into it is used. Its resource is significantly less than in the hub. Therefore, periodic diagnostics and determination of its actual state are required.

Malfunction manifestation and the simplest diagnostic option

The wear of the bearing is indicated by the appearance of vibration, crunch, hum, deviation from a straight line when the car is moving on an Smooth section of the road, the howling of the car on sharp turns, Strong heating of the hub or its cap (palpable with the palm).

You can verify its malfunction by performing a number of simple manipulations. Twice a month, each of the wheels should be pumped (after hanging it on a jack) with your hands, in order to detect backlash or extraneous sounds. The failure of the product will be indicated by the appearance of a significant backlash when the wheel sways in two planes (axial and axial).

As a rule, single-row tapered bearings are more often installed in the hubs of axles standing on the driven axle (they are subjected to lower loads). And for the presenters, double-row ones are in demand. These products are closed and, most often, maintenance-free.

Their timely replacement will ensure the safe operation of your vehicle.

Algorithm for replacing a faulty bearing

When deciding on an independent replacement of the front (PSP) wheel bearing, you should, first of all, take into account the place of its installation. The front suspension is the most important element on which the car’s handling depends.

It is recommended to work with a puller. Before starting work, the car is exposed on a flat surface and is fixed against unauthorized displaced (wheel stops, handbrake, first gear).

The work area must be carefully prepared. First, you should mentally “change” the bearing, determining in what sequence it is better to do this, and what tool will be required to perform each operation.

Please note that some car models have a pair of bearings in the front wheel hubs (if they are driving).

The universal replacement algorithm is the following.

  • The decorative disc of the front wheel is removed, the hub nut is released and loosened.
  • The wheel is hung on a jack.
  • The caliper is tied to the suspension element, so that in the future it does not hang on the brake hose.
  • The brake disc is unscrewed and removed.
  • Retaining ring is removed.
  • Using a puller, remove the old bearing.
  • Serves the Seat, checking its actual condition. Apply new grease.
  • Using a puller, press in a new bearing (check that there is no distortion).
  • Secure it with a circlip.
  • Fix it on the axle with the introduction of a washer and a thrust nut.
  • Tightening the latter, set the Required level of backlash.

After completing the replacement work, it is recommended to check the vehicle’s performance (test drive with turns and accelerations). Monitor the presence of extraneous noise.

Recheck steering play. It is advisable to carry out the operation of setting camber / convergence.

The work on replacing the bearing on cars of different brands, models and years of production may differ in the list and sequence of operations performed.

For example, a number of new cars, especially imported ones, are equipped with a significant amount of built-in electronics, which can be easily damaged during operation. Therefore, it is recommended to first dismantle it.

What types of woods are there

The most common type of line, which is suitable for almost all types of reels, is a round cord. This is an ordinary fishing line, suitable for cutting succulent grass, but it will be much more difficult to mow dead wood with it, and even more so it will not cope with shrubs.

As a rule, the diameter, which can mow young grass, and does not exceed 1.6 mm. The thicker the thread, the more coarse grass it can overcome.

There are fishing lines with sharp edges in the form of an asterisk or a square, this option is more adapted to mowing dry grass precisely due to the existing sharp edges, but its disadvantage is greater wear and tear and it is inferior in strength to round cord.

There are fishing lines with improved aerodynamics with characteristic dents, scales and notches, such a product makes less noise, but it is used only for lawn mowers, since the exit of such a thread from the reel is difficult, it is used most often with discs in which the segments are inserted. The disadvantage of such a product is its fragility.

Most often in gasoline trimmers with an engine power of more than 1.5 HP. Use cords with a metal cable inside.

This thread is ideal for cutting dry grass and small bushes. The presence of a core has a positive effect on the wear resistance of this material.

The disadvantage of such a cord is its price, which is significantly higher than the listed opponents.

How to change the line to the trimmer and which one is better to choose

Since we considered the choice of a trimmer in a previous article, today we will tell you how to properly fill the trimmer with a fishing line, and which one is better to choose Based on the working conditions.

After you bought a trimmer and began to actively use it, sooner or later the question of replacing the fishing line will arise, since this is the most wearing out element in the tool, intensive use of the trimmer will lead to frequent replacement of consumables.

How to remove or tuck the line into the trimmer

In order to wind the line, it will take about 10-15 minutes. What is a trimmer coil? Plastic body with a cassette inside, on which there is a special hook for easy winding of the fishing line.

Almost all trimmer reels have a similar fastening principle, this is a central screw-button, when pressed, it becomes possible to stretch the line of the required length. The photo below shows a few examples of different trimmer spools.

The bobbins of the trimmers, the motor of which is located in the ground itself, have a different attachment to the axis of rotation, they have two buttons on the coil on the sides, which must be wrung out, otherwise the whine replacement is not different from other cassettes.

The principle of correct winding of the fishing line is similar in all of the above cases, therefore, for example, consider the standard version with two tendrils.

To remove the spool with the fishing line, it is necessary to Unscrew, located in the center, the screw, but Note that the thread is left there, so it will have to be turned clockwise, this was done on purpose so that during operation It does not open under the influence of centrifugal force.

Next, using a screwdriver, disassemble the head and remove the spool onto which the fishing line is directly wound.

Having measured the required length and folded in half, you need to tuck the fishing line into the spool.We bring out, in total, its ends opposite each other (for this there are special slots for fixing).

After that, it is necessary to assemble the head in the reverse order, threading the ends of the cord into two corresponding holes.

If in doubt or it is not entirely clear how to load the line on the trimmer, we recommend that you look at: how to properly wind the line into the lawn mower.

In this, step by step, the instructor will open the trimmer head, measure the required amount of line, usually from two to four meters, and demonstrate assembly and installation on the trimmer.

Required tools

If you need to change the bearing in a concrete mixer, you can resort to the services of craftsmen. However, this will take time and require serious financial investments. To save money, it is recommended to do the repair yourself. It is not difficult to set up the unit yourself. To do this, you need to arm yourself with the necessary tools and theoretical knowledge.

For work you will need:

  • 2 new bearings (standard part size 6203)
  • A set of wrenches of different sizes;
  • Hammer or sledgehammer;
  • Angle Grinder;
  • Metal insert;
  • Thinner or gasoline for cleaning parts;
  • A solution designed to “oxidize” bolts (wd-40 is suitable for THESE purposes);
  • Screwdrivers of various configurations and sizes;
  • Pliers and pullers (pressure can be used instead).

Separately, it should be said about the choice of bearing. They are of 3 types. caprolon, bronze or steel. The first are the most popular. When choosing, you need to give preference to parts with a washer. they are able to withstand large mechanical loads and protect the internal device from the ingress of mechanical particles.

Causes and signs of breakage

During intensive use of a concrete mixer, one of the 2 bearings most often breaks. Signs of its failure:

  • Extraneous noises in the drum, similar to crunching or crackling;
  • Sudden drum stop even at low loads;
  • Slow start of the unit;
  • Perceptible backlash when rocking the bowl by hand.

There are several reasons why a part fails prematurely. The most common is unit overload. With an increase in the permissible load on the equipment (all standards are indicated in the technical documentation), the bearing assembly breaks down much faster.

Other less common causes include moisture, sand, small stones or other foreign matter getting under the bearing housing. And also the unit fails due to a previously installed low-quality part.

To prevent premature bearing failure, it is necessary to clean the unit from the remnants of adhered concrete mass after each use, and also to make sure that moisture, dust and sand do not get into the mechanism. There is no need to overload the equipment and try to make more concrete mix at a time than is allowed in the recommendations from the manufacturer. It is important to properly care for the mixer and perform timely maintenance.

How to remove a bearing from a drum?

To remove the damaged part, you need to get to it. for this you have to disassemble the mixer. First of all, turn the container over so that the traverse is at the top. After that, using a wrench, you need to Unscrew the bolt connecting the equipment shaft to the crosshead. Further it is necessary:

  • Remove the washer and grover;
  • Knock out the shaft from the traverse (for this, an insert with suitable dimensions and a hammer are used)
  • Disconnect the drum from the bed;
  • Remove the shims.

The next step is to detach the support structure from the pear. Many craftsmen warn that the retaining nuts, located on the outside, will rust over time. Such a negative process is inevitable, since the installed hardware comes into contact with moisture when preparing the working solution. To facilitate their removal, it is recommended to pre-treat the nuts with wd-40. After 10 minutes, you can try Unscrew the fasteners.

How To Change The Bearing On The Trimmer

After removing the fasteners, it is necessary to separate the resistance of the bowl from the drum, then Disconnect it into 2 parts. To do this, knock out the shaft with the bearing. Damaged parts are dismantled using special pullers or a vice.

How to change a bearing for a concrete mixer?

Household concrete mixers are mechanical (manual), with an internal combustion engine or electric drive. All of these species have a similar design. When preparing a concrete solution in a mixer, the bearing assembly is subjected to the greatest load. Over time, even if the rules for operating the equipment are observed, it fails. In the event of a breakdown, you should not look for a replacement for the broken unit. the bearing on the concrete mixer can be changed with your own hands, the functionality of the mixer has returned.

How to replace?

Before assembling the unit, it is recommended to pre-clean the shaft from dirt and rust using gasoline or an acetone-based solvent. After removing the formations on the parts, the new bearings should be pressed onto the shaft. It is convenient to use a special puller for this. In its absence, pressing is performed by uniformly tapping with a hammer on the inner race of the bearing assemblies. These work must be carried out carefully, tapping should be carried out through a block of wood.

The next step is to install the shaft in the lower part of the support, fix the second half on the upper bearing. After the performed manipulations, you need to fix the resistances to the drum using bolts, nuts and washers. To prevent the bolts from turning inside the structure, they must be held with a wrench. in this case, you cannot do without help. Before fixing the support, its perimeter should be processed in the areas of contact with the drum, for this you need to use any silicone-based sealant. Thanks to this additional processing, the bearing assembly will be reliably protected from accidental moisture penetration.

The last stage includes planting the adjusting washers, installing the shaft in the hole and fixing it with the pressure bolts.

After the performed repair manipulations, it is necessary to assess the performance of the concrete mixer. To do this, you need to turn on the equipment at idle, no load.

Timely replacement of the bearing is important. neglect of such work often leads to breakdown of the second units of the unit and their more expensive adjustment. The instructions given in the article will help to carry out a high-quality repair of a worn part, which, in turn, will help to extend the life of the equipment.

How to quickly and easily remove the coil with your own hands

Before replacing the old line with a new one in the detachable trimmer spool, you must remove the head.

The process is completely simple, even beginners can do the job:

  • Remove the upper fixing cover.
  • Remove the removable spool.
  • Get the spring out, if any.
  • Screwdriver Unscrew the bolt.
  • Remove the housing from the shaft.

Auto feed trimmer: how to wind the line into the removable spool

Some models of trimmers have a reel, the threading of which is automatic. It is enough for the owner to fix the ends in the head, after turning on the equipment, the mechanism will perform all the winding manipulations on its own.

By size

Before threading the thread onto the trimmer spool, pay attention to its size. Most often used fishing line with a cross section of 2 mm.

You can choose a suitable diameter in the following ways:

  • See recommendations in the manufacturer’s instructions for trimmers.
  • Manufacturers often apply cross-sectional information to the bobbin.
  • The cross-section of the cord must match the diameter of the reel hole.

What are the trimmers and features of their use

The trimmer is useful for mowing small or difficult areas, such as near hedges, between beds and along paths. Today manufacturers produce a wide variety of gasoline, electric and battery models, which can be selected for any owner’s request.

A fishing line is used as a cutting element of the trimmer. In the process of work, sooner or later, its length will end, and then the owner will have a question of how to correctly replace and fix the thread tucked into a removable coil.

How to wind the line on the detachable reel trimmer with two tendrils

You can see before work. And also take into account the following recommendations.

  • If there is only one track, both threads are wound parallel.
  • If there are two tracks, each piece is wound in a separate groove.
  • Wind the threads in the opposite direction to the rotation of the head.
  • The length of the risers does not have to exceed fifteen centimeters.
  • Thread the ends into the outlet holes.
  • Assemble the head and check the trimmer performance.

How to wind the line correctly: replacement features depending on the type of removable trimmer coil

To figure out how to tuck the line into the removable trimmer head, the following recommendations and instructions will help.

By quality

Before you put the line on the trimmer, you need to Pay attention to the section of the cord:

  • Whining with a circular cross-section is the most common option. They cut the grass perfectly even in difficult areas;
  • Spiral line is suitable for thin grass. It is not very durable and is NOT suitable for old thickets;
  • A cord with notches and sharp edges is chosen for mowing weeds;
  • A fishing line with a variety of geometric sections will help mow the lawn more evenly, but the strength of the consumables is low.

The owner of the lawn mower should know that it is absolutely forbidden to use metal wire, fishing thread and various strings.

How to properly wind the line around the trimmer: Step-by-step guide and instructions

A beautiful lawn will only look truly well-groomed if you regularly mow the grass. A trimmer is best for tackling difficult areas. Any owner of the unit will sooner or later face a solution to the problem of how to wind the line on a reel, because wrong actions can not only worsen the quality of the mowing, but also disable the equipment.

Things to consider when choosing a line

It is important to choose the right material before inserting and locking the line into the detachable trimmer spool.

Rating of the best petrol trimmer models. An overview of manufacturers and models, as well as useful tips from experts, considered in this review, will help in a difficult choice among many device models.

Major coil faults

Trimmer users and lawn mowers often face a problem with a semi-automatic mowing head. Coil malfunctions can be as follows:

  • The line does NOT extend automatically;
  • The cord spontaneously comes out of the reel.

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The picture below shows an exploded view of the Husqvarna (Husqvarna) Semi-Automatic Trimmer Head.

This type of head is present on most lawn mowers and trimmers such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

  • Mowing head base;
  • Button for semi-automatic cord feeding;
  • Spool (spool) into which the line is tucked;
  • Spring;
  • Eyelets. through them the line comes out;
  • Trimmer head cover;
  • Line (cord).

There are also simpler trim heads, shown in the following photo.

All these equipment do not allow changing the length of the line in a semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.

DIY trimmer coil repair

A petrol or electric trimmer is the only true solution for mowing grass in hard-to-reach places that a wheeled lawnmower does NOT. Trimmers use metal knives or special fishing line as a cutting tool, which is tucked into the trimmer coil. But, unfortunately, the trimmer heads become unusable over time during operation. Some malfunctions can be eliminated by hand, and with some you will need a complete replacement of the mowing head.

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. However, he never hit the ground with a button to lengthen the line. The reason that the line spontaneously lengthens, cutting into a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or completely lose it when opening the lid, and in the future, they do not even suspect of its existence.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, and not suspecting that it is unscrewed in the opposite direction. To prevent this from happening, if you need to change the tool, it is recommended to Read the Step-by-step instructions given below.

  • Stop the mowers engine or power off the trimmer before threading the line into the spool to avoid personal injury that could result from accidentally starting the cutting tool.
  • Unscrew the nozzle attached to the gearbox shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserted a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should know that the thread on the shaft is left-hand. Therefore, it turns the trimmer coil to the right, that is, clockwise.
  • Let’s disassemble the mowing head. Most often, the head cover is attached to a latch. To remove it, you need to sink these clips into the case, squeeze the edges of the cover. If your trimmer has a Semi-automatic mowing head with a button on the bottom, then the disassembly of the nozzle should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine stress and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. The cord should be tucked in as evenly as possible, the turns should lie down without overlap and with good tension. When the winding is finished, leave the free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if applicable) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or eyelets.
  • Put on the cover and lock it latches.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (against the arrows).

The line does NOT extend automatically

If the line is NOT lengthened by lightly hitting the trimmer button into the ground, the reasons for this may be the following.

Option 1. a bite has occurred, i.e. Clamping of the cord between turns. This problem usually appears if the user has been winding the line on the reel unevenly, with the intersection of turns, or winding it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil into trimmers and rewind the cord correctly, that is, in even turns with good tension.

Option 2. too short ends protrude from the head. The fishing line may not come out when it hits the ground if its ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, it is required to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull the line manually, after pressing the button.

Option 3. the line is soldered inside the mowing head. This causes the coil to lock and NOT spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during prolonged operation of the unit, line hitting hard objects.

  • In the first case, third-party cord can be made of low-quality and low-melting materials, which DO NOT withstand mechanical and temperature stress. Therefore, preference should be given “branded” line.
  • But, if you nevertheless purchased a fishing line of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after filling the cord into the reel, moisten it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of the coils of the fishing line being soldered together.
  • Also, the line may become soldered if it strikes a hard object (stone, fence, dry branch, etc.) during mowing. As a result, it stretches slightly and is pulled back into the head at high speed. Here the friction of the cord heats up, and its turns stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer spool and rewind the line.

Is it possible to make a trimmer coil with your own hands

  • Take a piece of plywood or PCB and draw a circle about 14 cm in diameter on it.
  • Cut the disc with a jigsaw or metal saw.
  • Drill a hole in the center of the disc that matches the diameter of the gearbox shaft. Do not forget to put a washer on it before installing the disc on the shaft.
  • Small corners can be screwed along the edges of the disc or 1-2 holes can be made on opposite sides. They will serve for filling the fishing line in them.
  • To fix the line, you can screw several screws into the plywood.

This homemade mowing attachment is attached to the shaft with a nut. Tighten or unscrew the nut without fixing the shaft. To replace the cord, it will be enough to loosen the screws, insert a piece of fishing line of the required length and press it again.

Also, the mowing attachment for attaching the fishing line to it can be made of metal sheet. How to do this can be understood from the following.
