Transmission, front axle and hydraulic
system
WARNING: Hydraulic fluid escaping under pressure
may have sufficient force to penetrate skin and cause
serious injury. Foreign fluid injected into the skin must
be surgically removed within a few hours by a doctor,
familiar with this form of injury, or gangrene may
result.
Before applying pressure to hydraulic system, make
sure all connections are tight and all hoses and lines
are in good condition. To find a leak under pressure,
use a piece of cardboard or wood — never use your
hands. Relieve all pressure in the system before dis-
connecting or working on hydraulic lines. To relieve
pressure, lower all attachments and shut off engine.
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 4-22
2. The oil is at the correct level when the oil level is within
the mark at the lower end of the dipstick. If low, add ISO
VG46 hydraulic oil, through the filler hole. Do not fill
beyond the mark on the stick, as the transmission will be
overfilled.
3. Install the dipstick.
Changing Oil & Filters:
NOTE: Replace the filters after the first 50 hours of opera-
tion and every 500 hours or annually thereafter following the
procedure below:
Change the oil every 500 hours or annually.
1. With the oil at normal operating temperature, drain and
discard the oil by removing the transmission drain plug.
Reinstall the plug after the oil has drained. Figure 4-23
WARNING: The oil will be hot. Use caution to pre-
vent skin coming in contact with hot oil.
2. Unscrew the oil filters and discard. Figure 4-24 & Figure
4-25
3. Coat the gasket on the new filters with a film of oil.
Screw the filters into place until the gasket contacts the
sealing surface, then tighten the filters approximately 3/4
of a turn by hand. Do not over tighten. Figure 4-24 &
Figure 4-25
4. Remove the filler plug and dipstick and fill with ISO
VG46 hydraulic oil.
5. The transmission is filled to the correct level when the oil
level is within the mark at the lower end of the dipstick.
Do not fill beyond the mark on the stick, as the
transmission will be overfilled.
6. Install the dipstick and filler plug.
7. Start the engine and check the hydraulic oil filter for
leaks.
8. Stop the engine and check the hydraulic oil level.
Replenish if necessary.
IMPORTANT: The transmission, front axle and hydraulic
system operate from a common oil sump. Special attention must
be given to keeping oil clean.
Rear axle case and final reduction gear cases
Check the oil level every 100 hours.
1. Clean the area around the dipstick/filler plug to prevent
dirt from entering the rear axle housing. With the engine
off and the tractor standing level, check the oil level
using the combined dipstick/filler plug. The oil is at the
correct level when it reads between the two marks on the
dipstick.
