How to convert a single-axle tractor Neva to 92 gasoline

TRACTOR SERVICE HACKS!! DON’T MAKE THIS MISTAKE!! MASSEY, FORD, JOHN DEERE, KUBOTA

Why, how it is.

Here we go. So they stopped. Naturally, without asking the citizens of the country, the owners of the equipment, about it. You, they say, and so it will work. Buy whatever gasoline is on sale, and that’s it. If your vehicle does not work there, it is “your” problem.

Strictly speaking, of course, this is not the problem of owners of vehicles for which they no longer produce the fuel for which it was designed. These are not even the problems of oil companies, though in respect of them one could remember the antimonopoly law, at least In fact the cessation of production of 80 petrol is very similar to the cartel conspiracy This is a problem of the state, in particular its legislature (i.e.е. The authority that approves/signs the laws), as well as the guaranteeing authority (i.e., the government that approves/signs the laws), and the guaranteeing authority (i.e.е. the one that is supposed to guarantee something there. something from the series of legal compliance, first of all with the Constitution of Russia, of course). But since this “guarantor”, as it were, is nowadays engaged in quite fascinating and “interesting” cases, often far from the state administration, then we have to solve the problem in other ways. Certainly it would be possible to devote a separate article to the legal aspects of the termination of the production of 80th petrol.

General description of the Neva MB 2

The device of this motor block, as well as other common models, includes certain elements. Let’s consider the main characteristics of the apparatus, as well as some inherent features:

• This model is equipped with a motor manufactured in the U.S. Briggs Stratton.
• The power of the motor is 6 horsepower.
• The fuel tank volume of the machine is 3.8 liters.
• Weight without attachments is 98 kilograms.
• The volume of the motor is 205 cubic centimeters.
• The transmission of the machine includes two forward gears and one reverse speed (21) × 2.

According to the manual, this machine can work the soil to a depth of 20 centimeters when tilling the soil. Track width is adjustable and ranges from 86 to 127 centimeters.

Important! If you use the grousers for the power tiller Neva or other attachments, the device performs a variety of functions (clearing the area of snow or leaves, plowing the ground, hilling the soil, watering, as well as transportation).

In this video you will learn more about the power tiller Neva:

What awaits the owner of a power tiller after switching to a new type of fuel?

To successfully use 92 gasoline instead of 80, after the modification it is necessary to follow certain rules when operating the equipment. By learning and following them, the owner of a power tiller will not make the mistakes typical of most inexperienced agrarians. During operation, you need to keep an eye on it:

• The condition of the cylinders. on their walls may accumulate fouling, formed by the evaporation of gasoline;
• Good condition of transmission. at first it may “fail” while shifting gears;
• Behind the appearance of strange sounds. they indicate a malfunction of the motor.

After the modification of the motor-block specialists advise not to overload the equipment for the first few months. Short pauses will help to avoid unwanted breakdowns.

Rarely are people interested in how to make 92 gasoline into 80. The most interesting situation is the reverse, when fuel with a low octane number must be converted into fuel with a higher octane. Today we will talk about how to lower the octane number of gasoline. The resulting fuel can be filled into chainsaws and even two-stroke moped engines that do not accept fuel with a high octane number. But in order to understand the process, we must first understand what is gasoline. Here we go.

Peculiarities of operating a converted power tiller

In order to extend the service life of the main mechanisms of a rebuilt motoblock, be sure to adhere to a number of rules. When working with an agricultural machine perform:

• Check the condition of the cylinders. regularly inspect the parts for fouling due to fuel evaporation;
• Check the serviceability of the transmission. at first it may “fail”, but later all the parts will fall into place and the mechanism will work properly.

Don’t overload the single-axle tractor in the first month after switching to a new fuel type. Otherwise the service life of the engine will be decreased rather quickly, what will lead to the engine failure. This will be indicated by the appearance of strange “shooting” sounds when the machine works.

Each of the above methods will be suitable for modification of power tillers produced under the brands Neva MB-1 and MB-2, MTZ-05 and MTZ-12, as well as units Cascade and Agro. The procedure when converting from 80 to 92 gasoline will be similar in each case.

What are the advantages of Texas cultivators?

A pleasant surprise will be the advantageous design of the steering wheel with a control panel, so that gear shifting will no longer be a problem. It is worth noting that the equipment of the specified brand is represented by several series, which should be familiarized with.

How to convert the engine of a power tiller from 80 to 92 gasoline?

The low-octane grades of gasoline. AI-76 and AI-80 disappeared from the responsible gas stations almost ten years ago, but the question of what to do with the technique, originally designed specifically for them, does not lose its relevance to this day. Thousands of users are convinced that thoughtlessly pouring 92 or 95 into the carbureted equipment is a very risky business that can lead to undesirable consequences.

It does not bypass the motor blocks, for the power part of which the “meeting” with the latest modifications of the fuel becomes a real test of endurance. Why does it happen and how to transfer cultivators from fuel AI-76 to AI-92 we will consider further.

Peculiarities of changing the lubrication of the four-stroke engine

Four-stroke engines use synthetic or semi-synthetic oil. Synthetic is much more expensive, but it wins in quality. Semi-synthetic oil is more affordable, but viscosity and temperature range must be taken into account when buying semi-synthetic oil.

It is very important to use exactly the right lubricant for the season. But more often the owners of power tillers use multigrade oil, it has a universal function and serves as a base for the excellent work of equipment regardless of the weather and temperature conditions.

Cylinder head (hereinafter. cylinder head). is the most important part in the construction of any gasoline engine, which controls the combustion process and gas extraction. It is located on top of the cylinders themselves. The purpose of its milling is to reduce the size of the combustion chamber, which in turn will increase compression and compression needed to run on high-octane gasoline. 3.5 mm is considered an acceptable degree of milling. This means that if conditionally the cylinder head on a power tiller was 95 mm, after milling it should stay 91.5 mm.

• remove the cylinder head after consecutively loosening the bolts and nuts;
• dismantle the caps and oil scoops;
• Remove probable soot, traces of oil and dirt with solvent. an ordinary acetone or diesel fuel will do;
• with a clean head start milling. You don’t have to look for a milling specialist to do it. If you have an emery wheel at home, you can do it with your own hands. Given that the cylinder heads of most motor-blocks are made of aluminum, not their cast iron, to create a perfectly flat surface of the set thickness, it will have to be sanded additionally with an emery cloth, attached to an even bar of wood or glass;
• After the visible grooves have disappeared, you can start polishing the working area of the valves.

After you clean the cooling fluid hoses from metal dust, you can install the cylinder head adjusted to the required dimensions.

In addition, to ensure that the rework is more reliable:

• put new caps and valves themselves;
• replace the used cylinder-head gasket;
• take reliable bolt ties (e.g., 1.1 cm in diameter) that are tightened with a torque wrench so that the load on the connection is 7.5 kg/sec. For studs of larger diameter, this figure is increased to 9.5 kg/s;
• as you tighten, make sure that the correct gaps of 0.3-0.35 mm between the outermost valves are maintained. For all others, up to 0.4 mm is acceptable;
• Considering that the cylinder head has shrunk in size, the native push rods of the cultivator will no longer fit. Shorter ones should be put in their place.

What are the advantages of engine modification for a new type of fuel?

Any equipment owner will not hesitate to answer the question “What kind of gasoline is better. 80 or 92?”. Gasoline AI-92 is much cleaner and better than 80 or 76. After a successful and high-quality modification of your power tiller engine for the new type of fuel the following advantages of the machine will be evident

• Long service life of important parts and systems of the motoblock;
• the need to change filters and oil seals as often as before will disappear;
• At the same time as reducing fuel consumption will increase the performance of the power tiller.

These undeniable advantages are worth it, not to put off converting your power tillage tillage for a long time.
