Gear Oil Viscosity
Select gear oil viscosity grade according to ambient tempera-
tures. If the new gear oil has a different viscosity grade compared
with the drained oil it is necessary to adjust the temperature
switch units according to the table on page 429.
REMARK
Before opening the access covers from below the pump dis-
tributor gear provide an adequate working platform with sufficient
space for the oil collecting container (approx. 100 liters).
Change the Oil
1. Remove drain plug (4), gauge (1) and filler plug (2).
2. Remove breather filter (3), blow out with compressed air from
inside to outside and re-install.
3. After the oil is completely drained, flush the gear with the reg-
ular gear oil and reinstall drain plug (4).
4. Fill in new oil through opening (2) up to the "MAX" mark on
gauge (1).
5. Re-install parts (1 and 2).
6. Vent the PTO lubrication pump, see page 411 for more infor-
mation.
7. After short operating period, check oil level and housing for
leakage.
REMARK
If the oil level is above the "MAX" mark, drain the oil down
until the oil level is at the "MAX" mark. Too much oil in the pump
distributor gear will cause aeration of the oil.
