4.7.11.b CHANGING THE REAR AXLE OIL
DANGER
•
Oils, filters, the coolant and the battery are considered
special waste and must be collected and disposed of ac-
cording to the anti-pollution regulations in force.
This operation must be carried out with the machine positioned
on level ground and at operating temperature, so that the oil be-
comes fluid and can be easily drained, which facilitates the elim-
ination of any suspended solid particles.
DIFFERENTIAL
1 - Remove the drain plug (2) and let the used oil flow out com-
pletely, gathering it into a container with suitable capacity.
While the oil flows out, remove the plug (1).
Use a 1/2” square spanner.
2 - Once the oil has been drained, put back the plug (2) and pour
oil of the prescribed type through the hole (1), until reaching
the level corresponding to the lower edge of the hole itself.
IMPORTANT
☞
•
With this operation both axle shafts are filled with oil; be-
fore checking the level definitively and putting back the
plug, wait a few minutes, in order to permit the uniform
distribution of the oil.
3 - Put back the plug (1).
FINAL REDUCTION GEARS
1 - Move the machine until the drain plug (4) is in low position on
the vertical axis.
2 - Remove the plug (3) and let the used oil flow out, collecting it
in a container with suitable capacity.
Use a 1/2”square spanner.
3 - After draining the oil, move the machine until the plug (3) that
serves also as level indicator is positioned on the horizontal
axis.
4 - Pour oil of the prescribed type until reaching the lower edge
of the hole itself.
5 - Put back the plug (3).
Carry out some forward and backward movements, stop the ma-
chine and check the levels again.
Always use oil of the prescribed type. (See “4.3 FUEL, COOL-
ANT AND LUBRICANTS”).
