How to remove the motor from a power tiller

Motor Replacement

Often the owner replaces the engine on the motor block not because of a malfunction, but because of a desire to get a more powerful technique.

remove, motor, power, tiller

This process will require a lot of knowledge, skills and special tools. When replacing the motors of different manufacturers may not match the holes for the fasteners, for compatibility which use the appropriate adapters or make new holes with a drill. If you are in doubt about the end result, it is better to refer to the masters.

It is necessary to take into account that the power of the new motor may not coincide with the weight of the whole unit, then there will be slippage of the motorblock when using the device with heavy loads. If this discrepancy is detected, the undercarriage, gearbox will be replaced, and subsequently you can get a technique that does not cope with its direct responsibilities in full.

The process of removal is as follows:

  • Disconnect hood guard, unscrew belt and crankshaft bolts, remove pulley.
  • Removing air cleaner filter and throttle cable.
  • Unscrew the four bolts that fasten the engine.

Special equipment, such as a single-axle tractor, is very useful in running a farm. The fact that power tillers are as balanced as possible in terms of price, cost and performance makes them a great advantage over tractors and other special equipment.

Many different operations can be carried out with it which are time-consuming and labour-intensive, using manpower and simple tools. All areas in which a single-axle tractor can be used are no longer source of disgust and unwillingness to work.

In fact, all work is reduced to driving. you just need to be present as a driver.

This is true both for modern machines and for older models of power tillers, because their design, in general, has not changed much over the decades. the weight has decreased, the variety of models has increased, and more advanced materials are used for manufacturing.

But the frame, the location of the engine and the way of controlling are the same, the attachments are essentially the same, the difference may be only external, in unimportant details.

That’s why good old power tillers, whose service life has already exceeded thirty years, are still in operation, year after year, doing their job. But every year they are more and more in need of repair and replacement of parts, components.

Every appliance wears out and needs to be repaired. And it’s worth paying a lot of attention, if, for example, you make long trips with a laden trailer. A jammed hub won’t be much of a problem, but a failure of a more complex part, such as the transmission, will be unpleasant, to say the least.

So you should familiarize yourself with all the “symptoms” of breakdowns, so that in time to diagnose and prevent malfunction.


single axle tractor MB 1 was very popular at one time, namely, in the eighties. nineties of the last century.

At that time, the market of special equipment, if it can be called such, was filled with products of Soviet factories, among the products of which the technique “Luch” was considered one of the best of its kind. The MB 1 single-axle tractor “Luch” was competing with the similar “Niva” power tiller.

It efficiently performed its main function. to cultivate a field or a vegetable garden, transport goods: crops, firewood, building materials. That was when the spread of homemade trailers began, and the tendency to turn these power tillers into minitractors settled.

Though the technical specifications of the “Beam” MB 1 is inferior to modern power tillers, at the peak of its distribution, they were at the height. the weight of the device assembled is a hundred kilograms, the speed of 3.6 to 9 kilometers per hour, on a level track, loaded, he consistently gives 8-99 kilometers per hour.

Acceleration up to a hundred, in principle, is possible, but only in very specific conditions that hardly anyone could recreate. Fuel consumption is 1,5-2 liters per hour, the volume of the fuel tank is 3.6 liters, so experienced drivers always have a reserve can with fuel.

Its big advantage is that the engine does not need a permanent oil fill. the timely maintenance is enough. The single-axle tractor is easy enough to operate. this process does not require much physical effort.

Minimum space required for turning has a radius of only 1100 millimeters. The unit shifts smoothly thanks to the chain reducer with V-belt drive and the gearshift is smooth and without jerks.

Gearbox: device, repair and oil change

The gearbox for the Oka motor unit is an important link. It is responsible for converting and transmitting energy from the engine to the wheel in the form of torque. The gearbox of an Oka motor unit can be divided into an outer part (gear case, shift knob, bearing, bearing cover, oil drain plug) and an inner part (input, intermediate, output shaft, sprockets, chains). The work of all these components of the gearbox is impossible to imagine without parts such as gaskets, nuts and bolts.

Repair of the Oka gearbox consists of disassembling it, checking its contents and replacing defective parts. These simple tasks will facilitate a quick and necessary repair.

Changing the oil in the gearbox of the engine block Oka previously requires the removal of gasoline from the fuel tank, as well as oil from the engine. After removing the oil drain plug from the transmission, tilt the entire unit to the right and drain the binder fluid. Then turn the engine block to its original position and add new oil recommended by the manufacturer.

How to put the starter on a single axle tractor. algorithm in detail

No problem with disassembling, disassembling and installing a manual starter motor unit, even for novice farmers. However, the assembly and installation of the electric starter for inexperienced motorcycle owners raises a number of questions. Due to improperly performed procedures, the engine starting mechanism refuses to work, resulting in the transport of the starter to the workshop. To avoid this need, we will learn how to install the starter on a single axle tractor at home. Installation is as follows:

  • To install and secure the crown on the flywheel, it must be removed. To do this, remove the block air filter to gain free access to the internal structure of the engine block;
  • Then remove the protective cover, unscrew the screws holding the manual starter basket, flywheel nut and the flywheel itself. Removing the starter flywheel can cause some difficulty, so it is best to purchase a special detachable wrench in advance to remove this item. When removing the flywheel, be sure to unscrew the wrench right behind it;
  • Next you need to install the alternator. At the same time, insert your wires into the hole in the steel wall of the engine and place the alternator on the seat on the engine wall;
  • Then install the alternator magnets inside the flywheel so that the holes in both elements line up. Connect the two parts with screws and install the head. Before doing this, the crown must be heated with a splash torch;
  • Install the assembled unit back on the engine while turning the wrenches and the flywheel hook;
  • Unscrew the manual starter basket, secure the housing, and replace the engine block air filter;
  • Then remove the starter mounting plug and install the starter on the engine block;
  • Then connect the alternator wires to the charging relay;
  • Connect the starter terminals to the unit battery and start the unit.
