Direction of Shaft Rotation

than the Vent plug from the upper side of the motor and connect an oil line from a gravity feed reservoir. Connect an overflow line to the Level Plug opening and run it to a pump to return the lubricant to the gravity feed reservoir.

If the Motor is mounted in any position other than that illustrated, contact an Ingersoll-Rand Representative for oil level and venting recommendations.

Series 92N Non–reversible Motors are assembled at the factory so that the Motor Shaft (36) rotates counterclockwise when facing the end of the Shaft. When desired, the direction of the shaft rotation can be changed as follows:

1.Stand the Motor upright on a workbench with the Motor Housing Cover (1) upward and secure it in position by clamping the base with a C–clamp.

2.Remove the four Housing Cover Cap Screws (2).

3.Being careful not to damage the Cylinder Seals (8A), pull the Motor Housing Cover and the Motor Housing (11) off the Gear Box (18).

4.Grasp the Cylinder (8) with both hands and carefully work the motor from the Gear Box.

5.While holding the Cylinder with one hand, drive against the splined end of the Rotor (12) with a soft hammer until the Front Rotor Bearing (13) comes free from the rotor shaft.

6.Withdraw the Front Rotor Bearing, Front Rotor Bearing Spacer Assembly (14) and Front End Plate (7).

7.Withdraw the Cylinder (8), turn it end–for–end, and slide it back over the Rotor.

8.Install the Front End Plate, Front Rotor Bearing Spacer Assembly and Front Rotor Bearing.

NOTICE

Press against the inner ring of the Bearing when pressing the Front Rotor Bearing on the rotor shaft.

9.Align the dowel hole in both End Plates and Cylinder, and insert the Cylinder Dowel (9) so that it protrudes from the Rear End Plate.

10.Place the Housing Cover Gasket (4) in the recess in the Housing Cover so that the dowel notch in the Gasket is aligned with the dowel hole in the Cover.

11.Set the motor assembly in the Cover so that the Cylinder Dowel enters the dowel hole.

12.Slide the Motor Housing (11) over the Cylinder and against the Motor Housing Cover.

13.Place the Gear Box Gasket (17) on the face of the Front End Plate.

14.Pick up the entire assembly and being careful not to damage the Cylinder Seals, work it into the pilot recess in the gear box.

15.Install the Housing Cover Cap Screws and, with the Motor running at a slow speed using air pressure of 30 to 40 psig (2.07 to 2.76 bar/207 to 276 kPa), alternately tighten the Screws to 28 to 31 ft–lb. (38.0 to 42.0 Nm) torque.
