2. Place a .002" shim into

01008

(Note: Shim Pack contains .001" and .002" shims.)

3. Install bearing/bearing plate assembly onto rotor. Tighten

4. Check clearance between rotor and bearing plate by using a .001" feeler gauge. Clearance should be at .001" to .0015".

Adjust clearance by repeating steps1-4 with different shim if necessary.

5. Once proper rotor/gap clearance is achieved, install well lubricated

recommends their air lube P/N 95842.

6. Install cylinder over rotor. Be sure air inlet holes of cylinder face away from bearing plate and that the

bearing plate aligns correctly with the pin-hole in the cylinder.

7. Press

Rear Bearing into

pin and air inlet holes line-up with pin slot and air inlet holes in cylinder.

Important: Fit must be snug between bearing plates and cylinder. A loose fit will not achieve the proper preload of motor

bearings. If too tight, rotor will not turn freely and must then be lightly tapped at press fit end so it will turn freely while still

maintaining a snug fit.

8. Secure housing in vise using
