Tractor Maintenance

General Overhaul Of The Tractors

A general overhaul of the tractor should be carried out if its further use is uneconomical, if most of its parts require a repair and its overall technical condition endangers traffic safety.

If all the maintenance instructions specified in the technical documentation of the manufacturer are observed and if work is carried out in a moderate climate and plain terrain, the mean service life of the engine and transmission system is 8000 hours of work.

This number of hours is valid on condition of the following distribution of tractor work:

If the tractor works in mountainous and sub-mountainous regions, the service life of the engine and transmission system is reduced by 15-20%.

If the tractor works under worsened climatic conditions, the service life of the engine and transmission system is reduced by 1520%.

Note: The transmission system includes the front driving axle.

Technical Maintenance Of The Tractors After A General Overhaul Of The Main Groups

Run in the tractor after a general overhaul in accordance with the instructions for running in a new tractor. Perform the maintenance in the same way as with a new tractor.

The driver of the tractor can do most of the planned maintenance work by himself. However, if you do not have sufficient technical equipment, entrust the execution of more complicated tasks to a specialized workshop.

All the work related to the cleaning, lubrication and adjustment of the tractor or attached implements may only be performed after stopping of the engine and other movable parts except the brake control and charging.

Maintenance Instructions

Opening The Hood

Release the hood by pressing the button (1), grasp it in the places of arrows and lift it. Thanks to a gas brace the hood will open automatically after that. The hood is locked in this lifted position thanks to this gas-liquid brace. Closing the hood: Pull the hood down with the strap, grasp it in the place of arrows and press it downwards until the hood lock snaps. Do not use excessive force to close the front hood as the filaments of headlight bulbs situated in the front hood might get damaged.

Checking The Oil Level In The Engine

Check the oil level daily before starting work with the tractor in the horizontal position. Unscrew the dipstick, wipe it with a piece of cloth and screw it back in. After repeated removal of the dipstick the oil level must not drop below the lower mark. Replenish oil as necessary through the filling opening.

Draining Oil From The Engine

Drain oil by unscrewing the drain plug (3), best immediately after a drive or after heating the engine to the working temperature. Clean the drain plug before returning it to its place. Check the sealing ring for integrity.

REPLACING THE FULL-FLOW ENGINE OIL CLEANER

The cleaner is replaced at every engine oil replacement. Before installing the new cleaner clean the sealing surface of the housing (1) and the cleaner (2). Coat the rubber sealing with oil that you will fill the engine with and tighten the cleaner by hand. When the sealing gets in contact with the block sealing, tighten the cleaner again by 3/4 to 1 1/4 turns. Check the cleaner for possible leaks after starting the engine.

Filling The Engine With Oil

Pour the prescribed quantity of engine oil into the filling opening (2), start the engine and let it run for 2 - 3 minutes at 750 - 800 rpm.

After stopping of the engine and level stabilization use the dipstick (1) to check the oil level and check the cleaner, drain plug (3) and other joints for leaks.

Replacing The Fuel Filter Element

Replace the filter element after releasing the nut (1) and unscrewing the bowl (2). During the re-assembly of the cleaned bowl with the new filter element check proper seating of the bowl gasket. Bleed the fuel system.

During the cleaning and replacement of the filter elements place a suitable vessel under the engine to catch dripping fuel.

Bleeding The Fuel System

Before bleeding place a suitable container under the engine to collect dripping fuel from the filter and injection pump.

1. Prime the fuel system with several strokes of the manual control of the priming pump (1).

2. Release the screw (2) of the fitting of the fuel inlet to the filter and let the foam escape.

3. Retighten the screw and repeat the procedure until after releasing of the screw clear fuel starts to continuously flow from the filter.

4. Bleed the injection pump in the same way.

5. Do the bleeding with the screw (3) positioned on the pump body.

Dry Air Cleaner Maintenance Instructions

Perform maintenance of the air cleaner in the following way:

1. Remove the right side plate of the hood

2. Release the clamps of the air cleaner lid (marked with arrows)

3. Remove the air cleaner lid (1)
