Hydrostatic Transmission (HST) Oil Filter

Change HST oil filter (A) initially at 50 hours and subsequently at every 350 hours of operation.

Transmission Oil Cooler

Transmission Oil Cooler (B) is fitted in front of the radiator. It helps in cooling the transmission oil to have better performance.

DO’S

1.Ports to be protected from ingress of dirt and foreign particles.

2.Always keep oil cooler in vertical position to avoid fin damage.

3.Use correct torquing of oil cooler inlet and outlet connectors.

4.Periodically remove fin clogging with pressurized air flow from reverse side of oil cooler.

5.Always use filtered oil.

6.Periodically clean inside passage of cooler with "Try Chloro Ethylene" to remove tubulator clogging.

DONT’S

1.Do not rinse the oil cooler with water.

2.Do not pressurize cooler beyond 300 psi pressure.

3.Do not paint the threaded area and spot face / sealing surface.

4.Do not paint the fins.

5.Do not weld or fit any type of mounting on cooler.

6.Do not repair the cooler if it is leaking. Incase of leakage, replace with new unit.

7.Do not try to tilt elbow/toil ports as these are brazed to avoid physical damage.

8.Do not use damaged oil cooler.

Front Axle - Front Wheel “Toe-in” Check

In the event of the tie rod setting being interfered with, it is necessary to adjust the TOE-IN. Before measuring and adjusting the TOE-IN, ensure the front wheels are in the straight ahead position and the front axle is not tilted. After adjusting the front wheel tread and with all connections secured, the front wheel Toe-in shall be as follows,

Model

Toe-in Value inch.mm.

3535/4035/4535/50350-0.230-6

Measure the distance between the outer edges of the wheel rims at the same height as the hub caps. Mark the point measured and turn the wheels half revolution so that the marked points are at the rear. Measure again the distance between these two points and this distance must be the same as measured before without variance. To adjust the TOE-IN shorten or extend the tie rod clockwise or anti-clockwise.
