Tool Disassembly Complete:

Motor Disassembly:

1. Secure the 96346 Bearing Separator (2") around the end of the cylinder nearest the rear bearing plate. Place the separator on the table

of the 96232 Arbor Press so that the front of the motor is pointing down.

2. Use a 5/32" diameter flat end drive punch as a press tool and push the rotor out of the 02696 Bearing.

3. Remove vanes from the rotor.

4. Use the arbor press and separator to remove the front bearing, plate and spacer from the rotor.

5. Remove the 02696 Bearing from the rear bearing plate with the 96210 Bearing Removal Tool and the arbor press.

Motor Disassembly Complete:

Important: Clean and inspect all parts before assembling.

Motor Assembly:

1. Install 01479 Spacer onto the rotor.

2. Install .003" thickness of shims into 02038 Front Bearing Plate. Install 02649 Bearing into the front bearing plate.

3. Use the 96240 Bearing Press Tool and arbor press to install the front bearing plate along with 02649 Bearing onto the rotor. (Place the press tool

against the inside race of the bearing.)

4. Use a .001" feeler gauge to check clearance between the front of the rotor and the front bearing plate. That clearance must be .001"- .0015". If it is

necessary to adjust the clearance, do this by adding or removing the appropriate shim thickness.

5. Apply Dynabrade Air Lube 95842 to the 01480 Vanes (4) and install these into the rotor slots.

6. Install the 01476 Cylinder so that the air inlet passage lines up with the air inlet holes in the rear bearing plate.

7. Use the 96242 Bearing Press Tool and arbor press to install the 02696 Bearing into the 02673 Rear Bearing Plate. (Place press tool against the

outside race of the bearing.)

8. Use the 96242 Bearing Press Tool and arbor press to install the bearing/rear plate onto the rotor. (Place press tool against the inside race of the

bearing.) Important: Carefully press the bearing/rear plate assembly onto the rotor to achieve a snug fit between the bearing plates and the cylinder.
