Install the tractor on a horizontal ground. In order to check the oil level, undo the plug from the
reference hole. The oil level in the main gear case shall coincide with the lower edge of the
reference port. Fill oil through the reference port by means of funnel with hose and drain oil
through the port in the bottom part of the case. Before filling unscrew the breather and close the
port with a plug. Wash the breather in diesel fuel, blowdown with compressed air and install it in
place.
Check of the level, filling and change of oil in final gears
In order to check the level and fill oil in final gears, it is necessary to place one of the two
triangular marks 1 (Fig.35) on the pinion carrier in the extreme lower position and undo plug 2.
Fill oil by means of funnel. Drain oil through the drain port (reference) when it is located in the
bottom position using the attachment for oil drainage.
Change oil in the following sequence:
– install one of the pinion carriers in the oil drainage position;
– drain oil from the final gear;
– install the second pinion carrier in the oil drainage position;
– drain oil from the second final gear;
– fill fresh oil into the first final gear and screw the plug.
Change oil in the remaining final gears in a similar manner.
