NOTE:

These consist of 2 CbN gear units assembled together. Each gear unit has a separate oil sump that is factory filled and requires monitoring before start-up and during operation. The table at left defines the gear size, and type for each CbN gear of a specific “combined” gear reducer.

Refer to the table above for oil volume based on mounting position specified

Oil sumps of frames 36, 37, and 38 are equipped with a dipstick (with breather) for the purposes of oil level monitoring when a unit

is not operating.

Oil sumps of frames 31 through 35 are equipped with an oil level plugs for the purposes of

oil level monitoring when that unit is not operating .
