Agriculture is increasingly gainingpopularity in Russia. But not everyone can afford to purchase new equipment, for processing fields and harvesting. If the area is small, then a small and versatile transport is best suited for operation, while being relatively cheap.
T-40 tractor
The T-40 is a tractor that has become almost a legend. The famous brand, which was produced in the period from 1961 until 1991 at the tractor factory, located in the city of Lipetsk.
This tractor T-40 was mainly used forplowing fields, as well as processing fairly light soils. Harvesting hay is not excluded. Due to the small size and at the same time acceptable power, the tractor was also used for working in the greenhouse, as well as for a variety of cargo transportation.
Design
T-40 - a tractor with quite standardsemi-frame structure, which consists of a carrier box for shifting gears, as well as a dependent rear axle. The motor is located in the front, it is installed on a small separate frame, which, in turn, is rigidly attached to the T-40 transmission case. The tractor is famous for reliable rear-wheel drive, the rotation is transmitted to the wheels with a larger diameter. The wheels are attached to the frame with a rigid suspension.
Front, part-time guides,wheels are much smaller in diameter than the rear. Tractor T-40 AM differs from all other modifications also driven on the front axle. On the vehicle, designers have the opportunity to adjust and when changing the type of work to change the ground clearance, as well as the wheel track. To be able to work on very steep slopes in order to ensure normal stability, it is possible to increase the track width. On the tractor T-40 wheels are installed by the method "inside out".
Engine
The T-40 is a tractor on which, regardless ofcomplete set install diesel engine brand D-37. A feature of such a power plant is the presence of an air cooling system. The T-40 tractor (photo below) can also be equipped with a D-144 motor with a power of 50 horses. Earlier versions were launched using an additional engine brand PD-8, running on gasoline. For later configurations installed electric starter with the ability to run from the cabin cabin.
Transmission
Thanks to a specially designed reversibleThe system installed on the T-40 can operate the tractor using the entire set of available speeds when moving both forward and backward. An interesting feature of the design is the location of the bevel gearbox. It is located immediately after the clutch, and as a result of this, the transmission shafts had to be installed transversely. To carry out work at low speeds, it is possible to install an additional creeper, operating with a hydrostatic or mechanical drive. The T-40 has two shafts for power takeoffs - one at the rear, and the other at the side. Repair of the tractor T-40 is much easier to implement, just because of the convenient location of all the working units.
Job
This tractor can workwith almost any mounted or trailed equipment, which was developed for heavier models, such as MTZ, as well as lighter, like the T-25. This is one of the most important advantages, since there is no need to create separate equipment for this model or modify the existing one. The presence of two multi-mode PTO can significantly increase the scope of this technology.
Engine repair
Sometimes there are situations when duringWork one of the parts stops working normally, this can not be avoided, you can only fix it. The most common problem that the T-40 tractor "suffers" (its photos are given in the article) and its engine - sometimes the engine does not start. The main reason for this - the appearance of blockages in the inner part of the fuel line. To fix it is quite simple - you need to rinse all the hoses, after which they are purged and dried. Only after that try to start the power plant again. In some cases, everything is much simpler - the air got into the pipeline. The solution is to remove the air bubble by completely filling the system. If the filters are out of order, it will not be difficult to wash them and replace them due to the convenient location of the working elements on the frame.
Sometimes the motor may not work at full strength eitherwith a few interruptions. In this case, there may be several reasons: air in the power supply system (this can be solved by blowing and cleaning); Also, the cause of unstable operation may be the hang of individual elements - valves in the head of the block, plunger or needle, which is used in the nozzle spray. All items must be removed and cleaned. If cleaning does not give the desired result, replace with new ones.
Перед началом ремонта трактора Т-40 необходимо check the fuel line for blockages and also diagnose the pump. The condition of the air filter can affect the normal start of the motor. With insufficient air, an enriched mixture is obtained. The result of this may be unstable operation of the power unit, as well as increased fuel consumption at relatively low power, uncharacteristic for such an engine.
Front axle
On the T-40, the front axle does not play the latestrole, especially when working or driving in off-road conditions. In the T-40AM he is leading, thanks to which the thrust is significantly increased, as well as the level of maneuverability of the vehicle. Main work items:
- gearbox;
- transfer case;
- differential;
- suspension;
- final transfer.
In the T-40AM main gear consists of two gears, one of which - the leading, and the second at the same time - the slave.
The differential is necessary in order to be able to rotate the wheels at an angle (while overcoming irregularities or when turning), as well as at different speeds.
The transfer box acts as a kind of binder between the wheels, as well as the drive. The final gears are set to lower the speed.
It is very important to remember that in the case of installing wheels with a rather large diameter and with the front axle off, the slip of the wheels located behind may occur.
