Mounting Positions
Why Are Mounting Positions Important?
Mounting positions determine:
- Oil Quantity
- Bearing Lubrication
Reducer filled
according to M1,but mounted atM4

Mounting Positions
Special Assembly Required for Some Mounting Positions
- K-Box reducer assembled for M1 cannot be used for M5 or M6
NILOS rings are used oncertain mounting positionsto retain grease in a bearing.
This procedure is necessarybecause the oil level does
not reach some bearings incertain mounting positions.
What effect will not using a
NILOS ring have on a K-boxmounted at M5 or M6?

Breather Plugs
What is a breather plug?- A breather plug is a device that allows the gearbox to breathe, thus
equalizing internal and external pressure.
Air inside the reducerexpands duringoperation and contracts
when not in operation.
