4. Install bearing/bearing plate assembly onto rotor.

5. Install 01815 Rotor Nut onto assembly.

6. Tighten rotor nut onto rotor, torque 22.5 N•m/200 in. - lbs.

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

steps 1-5 with different shims if necessary.

8. Once proper rotor/gap clearance is achieved, install well lubricated 52474 Blades (4) into rotor slots. Dynabrade Air Lube P/N 95842 (or equivalent) is

recommended for lubrication before installation in rotor slots.

without drag. If drag or rub is felt, then increase preload or remove shim. Also, push end of rotor and twist (10-15 lbs. force), rotor should turn freely

without drag. If drag or rub is felt, then deload or add a shim.

20. Tighten 52495 Nut to 45 N•m/400 in. - lbs. Roll 07136 Grip back into place.

Tool assembly is complete. Please allow 30 minutes for adhesives to cure before operating tool.

Important: Motor should now be tested for proper operation at 90 PSI. If motor does not operate properly or operates at a higher RPM than marked on the

tool, the tool should be serviced to correct the cause before use. Before operating, place 2-3 drops of Dynabrade Air Lube (P/N 95842) directly into air inlet

with throttle lever depressed. Operate tool for thirty seconds to determine if tool is operating properly and to allow lubricating oils to properly penetrate motor.
