Traction reduction gear oil level check and change
The oil level should be checked at least once a year. Position
the reducers until the two caps
A
and
B
reach the position
1
indicated in the picture aside. Visually check the level by
means of one of the two caps. Oil check must be carried out
when the oil is hot. The level is correct when the reduction
gear body is full of oil up to the cap limit. Should a lubricant
volume higher than 10% be topped up, check that there is no
leakage in the group. Do not mix different types of oil, of the
same or of different brands. Do not mix mineral oils and
synthetic oils. The oil must be changed the first time after 50-
100 working hours, and afterwards after every 2500 working
hours or at least every two years. Depending on the actual
working conditions, these periods may be modified according
to the single case. While changing the oil it is advisable to
wash the internal part of the crankcase with a fluid
recommended by the lubricant producer. To avoid sludge
deposits, the oil must be changed when the reduction gear is
hot. To perform the oil change position the reducers until
caps
A
and
B
reach position
2
indicated in the picture aside.
Unscrew cap
A
and place a container of a 0.5-litre capacity
under it. Empty the reducer body completely, clean it as
described above. Finally before repositioning the reducers in
