shaft until the Front End Plate nearly contacts the rotor body.
In the following step, the measurement must be made at the end corner of the large rotor body.
3.The clearance between the Front End Plate and Rotor is critical. While pressing down with your finger on the outer edge of the Front End Plate on the bearing side, insert a 0.004” (0.1 mm) feeler gauge between the face of the rotor body and the face of the End Plate at a point that is 180 degrees from where the pressure is applied. Refer to Dwg. TPA1740. To increase the gap, support the End Plate and lightly tap the rotor shaft with a plastic hammer; to decrease the gap, press the Bearing farther onto the rotor shaft.

4.Wipe each Vane (28) with a light film of Ingersoll- Rand No.10 Oil and place a Vane in each slot in the Rotor.
5.One end of the Cylinder Assembly (24) has a notch that breaks the outer wall and end face of the Cylin- der. With that end trailing, install the Cylinder Assem- bly over the Rotor and Vanes against the Front End Plate. Make certain the Cylinder Front Alignment Pin (26) enters the hole in the Front End Plate.
6.Install the Rear End Plate Assembly (21), flat face leading, on the rear hub of the Rotor. Make certain the Cylinder Rear Alignment Pin (25) enters the hole in the Rear End Plate.
7.Examine the Rear End Plate Face Plate (22) for scratches. If it is scratched, replace it. If it is not, slide it onto the rear hub of the Rotor and onto the Cylin- der Rear Alignment Pin against the Rear End Plate. Some pressure may be required to fit the hole in the Plate onto the Alignment Pin.
8.Using snap ring pliers, install the Rear End Plate Assembly Retainer (23) in the annular groove on the rear rotor hub to secure the assembly in position.
9.Set the assembled motor aside.
Assembly of the Gearing
1.Using a small screwdriver, work the Spindle Bearing Seat (46) into the internal groove nearest the notched end of the Gear Case (43).
2.Stand the Gear Case, notched end upward, on the table of an arbor press. Using a piece of tubing that contacts the outer race of the Spindle Bearing (44), press a new Bearing into the Gear Case against the Seat.
3.Lubricate the gears in the Spindle Assembly (42) with
4.Invert the Gear Case and using another piece of tub- ing that supports the inner race of the Bearing and clears the output end of the Spindle Assembly, press the Spindle Assembly into the Bearing from the motor end of the Gear Case.
5.Using snap ring pliers, install the Spindle Bearing Retaining Ring (45) in the external groove near the driver end of the spindle.
6.Lightly lubricate the Planet Gear Head Spacer (41) with
7.Lubricate the shafts of the Planet Gear Head Assem- bly (38) with
8.For Series QS1L02, QS1T02, QS1L05, QS1T05, QS1L10 and QS1T10, lubricate the Planet Gears (39) with
For Series QS1L17, QS1T17, QS1L20 and QS1T20, lubricate the Planet Gears (39) and Gear Head Pinion (40) with
9.Install the Gear Head Spacer (36) against the Gears or Drive Plate and secure the assembly by using snap ring pliers to install the Gear Retainer (35) in the internal groove at the motor end of the Gear Case.
Assembly of the Adjustable Cushion Clutch
1.Insert the small end of the Clutch Shaft (68) into the end of the Cam Jaw (70) having the large opening and slide the Shaft about half way into the Jaw.
