WARNING
General Product Safety Information
Read and understand this manual before operating this product.
It is your responsibility to make this safety information available to others that will operate this product.
Failure to observe the following warnings could result in injury.
WARNING
Always operate, inspect and maintain this motor in accordance with American National Standards Institute Safety Code for Portable Air Tools
(ANSI B186.1).
For safety,top performance and maximum durability of parts, operate this motor at 90 psig (6.2 bar/620 kPa) air pressure at the inlet with
1 1/4” (32 mm) air supply hose.
Always turn o the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this motor or
before performing any maintenance on this motor.
Keep hands, loose clothing and long hair away from rotating end of motor.
Anticipate and be alert for sudden changes in motion during start up and operation of any motor.
Motor shaft may continue to rotate briey after throttle is released.
Do not lubricate motor with ammable or volatile liquids such as kerosene, diesel or jet fuel.
Do not remove any labels. Replace any damaged label.
Use accessories recommended by Ingersoll Rand.
This motor is not designed for working in explosive atmospheres.
This motor is not insulated against electric shock.
Series 92RMG and Series 992RMG Motors are designed for gas operation. They are not totally sealed in dynamic operation since the exhaust
must be vented or piped away and there is a possibility of leakage around the output shaft when rotating. Caution should be taken when
operating these motors on gas because of the danger of re, explosion, or inhalation.
Motors for operation on compressed gas incorporate special sealing to prevent gas leakage. This includes a Cylinder Seal (9) at each end of
the Motor Housing (12), and an O-ring type Gear Case Cover Seal (14) located in a groove in the Gear Case (13). Gas operated Motors also use
a special Drive Shaft Grease Seal (20); never use a substitute Seal. A Drive Shaft Grease Seal is included in the Gear Case Cover Assembly (19);
therefore, be sure to use the proper Assembly as listed in the part list section.
Motors for gas operation can be operated with compressed air, but Motors for air operation must never be operated with gas unless
completely converted by the installation of the Cylinder Seals (9), Gear Case Cover Seal (14) and special Drive Shaft Grease Seal
Part No. 150RMG14-271.
When installing one of these Motors for operation on compressed air, refer to the schematic diagram Drawing TPB-491.
NOTICE
The use of other than genuine Ingersoll Rand replacement parts may result in safety hazards, decreased tool performance and increased
maintenance, and may invalidate all warranties.
Ingersoll Rand is not responsible for customer modication of tools for applications on which Ingersoll Rand was not consulted.
Repairs should be made only by authorized, trained personnel. Consult your nearest Ingersoll Rand Authorized Servicenter.
It is the responsibility of the employer to place the information in this manual into the hands of the operator.

Placing the Motor In Service
Models 92RM1 and 92RM2 are identical except for the direction of
rotation of the Drive Shaft; likewise Models 92RMG1 and 92RMG2.
The direction of rotation is determined by the position of the
Cylinder (8), and can be changed by removing the Cylinder and
turning it end for end.
Models 92RM1, 92RMG1, 92RMG10, 992RM1 and 992RMG1 are
assembled at the factory so that the Drive Shaft rotates clockwise
when facing its output end; Models 92RM2 and 92RMG2 are
assembled for counterclockwise rotation.
Lubrication
Always use an air line lubricator with this Motor. We recommend
Ingersoll Rand No. NFLU-16 Filter Lubricator Unit. For temperatures
above 30° F, use SAE 20 motor oil. For temperatures below 30° F, use
SAE 10 or 10W motor oil. Set the lubricator valve to a medium feed or
approximately 60 drops per minute.
After each 200 hours of operation, lubricate the gears and bearings
with Ingersoll Rand Lubricant No. 28, or a good quality No. 2 cup
grease. Disassemble the Motor for lubrication as instructed in the
Maintenance Section beginning on page 6.
Reversible Motor Applications Air Flow Information
Important: When these motors are used on applications requiring a
reversible motor, a 4-way throttle valve or two 3-way throttle valves
must be used in the air supply line in accordance with the following
schematic diagram. When the application requires a non-reversible
motor, a 2-way inline valve can be used in the air supply line. In either
case, the inlet and outlet of the valve must be equal in size, and
preferably one size larger, than the inlet of the motor.

7. The direction of rotation of the Motor depends on the relationship
of the Cylinder and End Plates. To obtain desired shaft rotation,
proceed as follows:
a. Rotate the End Plate until the 17/64”(6.75 mm) through hole
(dowel hole) is facing you. Note there is a similar hole extending
lengthwise through the Cylinder (8), and at about 40° to one side
of the hole is an air port.
b. Hold the Cylinder upright, facing the dowel hole and with the
air port to the right for clockwise shaft rotation, to the left for
counterclockwise shaft rotation. Then place it over the Rotor so
that the dowel hole in the Cylinder and End Plate are in alignment.
8. Slide the other End Plate, the side with the channel going from the
central opening toward the outer edge trailing, onto the short hub
of the Rotor. Rotate it so that the cylinder dowel hole is aligned
with the corresponding hole in the Cylinder. Install the Cylinder
Dowel (10) to maintain the alignment.
9. Slide the Rear Rotor Bearing (5) on the short hub of the Rotor and
against the End Plate. Using snap ring pliers, install the Rear Rotor
Bearing Retainer (6) to keep the Bearing and End Plate in position.

(26) with the spline and move the Bearing forward until it stops
against the shoulder on the Shaft.
11. Insert the Drive Gear Key (18) into the slot in the spline portion
of the Shaft and slide the Drive Gear (17) onto the Shaft so that it
engages the spline and Key.
12. Slide the remaining Drive Shaft Bearing onto the Shaft against
the Gear and using snap ring pliers, install the Drive Shaft Retainer
(16) in the groove on the Drive Shaft.
13. Examine the slot in the output end of the Drive Shaft and if it is
dubbed or burred, stone the edges sharp and smooth.
14. Install the Drive Shaft Grease Seal (20),open end trailing, into the
recess in the Gear Case Cover.
15. If the Gear Case Cover Seal (14) was removed, work a new one
into the groove in the face of the Gear Case (13).
16. Carefully work the output end of the Drive Shaft through the
Grease Seal and push the assembly into the Gear Case Cover until
the leading Drive Shaft Bearing bottoms in the bearing recess.
17. Position the assembled Gear Case Cover and Drive Shaft against
the Gear Case and install the Gear Case Cover Cap Screws (28).
