POWER STEERING RESERVOIR
Checking Oil Level:
Check the oil level in the power
steering reservoir every 50 hours.
1.
With the engine stopped, the tractor standing
level, and the wheels in the straight-ahead position,
visually check the oil level (3) in the reservoir,
Figure 55, by removing the filler cap (2).
2.
The oil should be level with the bottom of the
filler neck. If low, add new oil of the type speci-
fied, page 70, and reinstall the filler cap.
3.
Start the engine and turn the steering wheel in
each direction several revolutions (five or more)
to purge air from the system.
4.
With the wheels in the straight-ahead position,
stop the engine and recheck the oil level. Add oil
as required and repeat Step 3.
Changing Oil Filter and Oil:
Change the oil filter and the
oil in the power steering reservoir every
600
hours.
REVERSIBLE SEAT (OPTIONAL)
The spring loaded lock pins in the reversible seat, Figure
56, should be lubricated with engine oil every 50 hours
to prevent the pins from rusting or seizing.
CAUTION:
Failure of the pins to engage
in the locked position will allow the
seat to tip backward.
