5.8 Transmission, oil - filter (4WD)
The oil and filter in the hydraulic power transmis-
sion must be checked/adjusted and changed at the
intervals given in the table below.
The type of oil is dependent on the hours of opera-
tion according to the table below:
Oil quantity when changing: approximately 3.5 li-
tres.
5.8.1 Check – adjustment
1. Place the machine on a flat surface.
2. Read off the oil level in the reservoir. See fig.
20. The level should be level with the line.
3. If necessary, top up with more oil.
5.8.2 Draining
1. Run the machine at variable speeds for 10-20
minutes to heat up the transmission oil.
2. Position the machine completely horizontally.
3. Pull out both disengagement levers according to
fig. 6.
4. Place one container under the rear axle and one
under the front axle.
5. Open the oil reservoir by removing the cover.
See 9:R.
Only a 3/8” square drive may be used
for the filter plug. Other tools will dam-
age the plug.
6. Remove the filter plug from the rear axle. Clean
the hole and use a 3/8” square drive. Remove
the filter and allow the oil in the rear axle and
reservoir to run out. See figure 11.
7. Remove 2 drain plugs from the front axle. Use
a 12 mm socket. Allow the oil in the front axle
and pipes to run out. See fig. 12.
8. Clean the filter (11:X) using a suitable solvent
and compressed air.
9. Check that the gaskets on the drain plugs of the
front axle are intact. See fig. 12. Reinstall the
plugs. Tightening torque: 15-17 Nm.
The filter plug will be damaged if it is
tightened more to than 5 Nm.
10. Check that the gasket on the filter plug of the
rear axle is intact. See fig. 11:Y. Reinstall the
filter and filter plug in the rear axle. Tighten the
filter plug to 5 Nm.
11.Draw out the oil from the deeper section of the
reservoir using an oil extractor. See fig. 13.
12.Dispose of the oil according to local regula-
tions.
5.8.3 Filling
The engine must never be run when the
rear clutch release lever is pushed in
and the front clutch release lever is
pulled out.
This will damage the front axle seals.
1.Fill the oil reservoir with the new oil.
If the engine is run indoors, exhaust ex-
traction equipment must be connected
to the engine’s exhaust pipe.
2. Check that the rear axle’s clutch release lever is
pulled out.
3. Start the engine. When the engine is started, the
front axle’s clutch release lever slides inwards
automatically.
4. Pull out the front axle’s clutch release lever.
NOTE! The oil is drawn into the system very
quickly. The reservoir must always be
topped up. Air must never be drawn in.
5. Set the accelerator pedal to the forward position
by blocking it using a wooden wedge. See fig.
14. Fill the oil reservoir by hand using new oil.
6. Run in the forward position for one minute.
7. Move the wooden wedge and set the accelerator
pedal to the reverse position. Continue filling
with oil.
8. Run in reverse mode for one minute.
9. Change driving direction once every minute as
above and continue filling with oil until the
bubbling in the reservoir stops.
10.Switch off the engine, install the oil reservoir
cover and close the engine cover.
11.Test drive for several minutes and adjust the oil
level in the reservoir.
