Maintenance of drive geared motors
Checking the oil level in the reduction unit
Replacement of oil in the reduction unit
IMPORTANT
Avoid using oils with different characteristics and brands.
Choice of type of reduction unit oil
We recommend, for reduction units, using gear oils with E.P. additives and viscosity class
according to ISO VG 150 or SAE 80W / 90. When temperature variation ranges are very
high we recommend using synthetic oils with E.P. properties and minimum 165 viscosity
index and viscosity class VG.

Every 100 hours check the oil level in the reduction unit
gearbox. Stop the hydraulic geared motor with plugs
aligned horizontal. Remove the plugs as shown in fig. A and
check that the oil level is up to their holes. Top up as
necessary, filling through one of the holes and using the
other to check the oil level.
Replace the oil after the first 100 operating hours and then
at subsequent 1000 hour intervales. Proceed as follows to
perform the replacement:
-
Stopp the reduction unit with the plugs aligned
vertically as illustrated in fig. B.
-
Remove both plugs and drain out all the oil.
-
Now position the plugs horizontal (fig. A) and fill
the reduction unit through one hole, using the
other to check the oil level.
