LUBRICATION AND MAINTENANCE
CLUTCH PEDAL ADJUSTMENT
To obtain maximum clutch life, it is essential that
the clutch pedal free travel be checked every 50
hours so as to maintain free travel at 3/4 -1-3/16
inches (19-30 mm), Figure 66.
1. Remove the cotter pin and clevis pin.
2. Turn the clevis to increase or decrease pedal
travel as required.

AND FINAL REDUCTION GEAR CASES
Checking Oil Level: Check the oil level every 50
hours.
1 With the tractor standing level and the engine
off, check the oil level with the dipstick,
Figure 67.

2. The oil is at the correct level when the oil
level is between the mark and lower end of
the dipstick. If low, add new oil of the type
specified, page 33, through the combined
dipstick/ filler plug. Do not fill beyond the
mark on the stick, as the front axle and
differential housing will be overfilled.
3. Install the dipstick/filler plug.
Changing Oil: Change the oil every 300 hours.
1 With the oil at normal operating temperature,
drain the oil by removing the front axle
differential, Figure 68, and final reduction
gear case drain plugs, Figure 69. Reinstall the
plugs after the oil has drained. Discard the oil.
2. Remove the filler plugs at each final reduction
gear case, Figure 69, and fill with new oil as
specified on page 33, and install the filler
plug.

3. Remove the dipstick/filler plug on the top,
right side of axle housing, Figure 67, and fill
with new oil of the type specified, page 33.
4. The front axle is filled to correct level when
the oil level is between the mark and lower
end of the stick. Do not fill beyond the full
mark on the stick, as the front axle will be
overfilled.
5. Install the dipstick/filler plug.
