DANGER
WARNING
CAUTION
NOTICE
Lubrication
Always use an air line lubricator with these motors. We
recommend the following Filter-Regulator-Lubricator Unit:
No. C31-08-600.
Install the Unit as close to the Motor as practical. Keep the
Lubricator filled with Ingersoll-Rand No. 50 Oil.
NOTICE
If a sight feed lubricator is used, adjust the lubricator to
feed 60 drops per minute for continuous duty operation.
Whenever the power unit is disassembled, work some
Ingersoll-Rand No. 28 Grease into the Rear Rotor Bearing
(5).
Use a good quality SAE 90 Gear Lubricant in the gear box.
The amount of lubricant required is dependent upon the size
of gear box and the mounting position of the Motor.
When lubricating the gear box, refer to Drawing TPB490
showing the various mounting positions and the fill plugs,
vent plug and drain plug. In each case, fill the gear chamber
up to the “Level” plug. If the Vent Plug (40) is not located at
the position indicated for a given mounting, relocate the Vent
Plug by interchanging it with the pipe plug at that location.
Whenever a Series 92NB or 92RB Motor is mounted with
the Motor Shaft (36) pointing toward the floor or ceiling,
you must install a gravity feed lubrication to make certain the
gears in the upper portion of the gear box get adequate
lubrication. To do this, remove one of the pipe plugs other
