Disassembly/Assembly Instructions Continuted

Motor Assembly Continued:

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

clearance by repeating steps 1-3 changing shims as required.

4. Once proper rotor gap clearance is achieved, install lubricated blades into rotor slots. (Use 95842 Dynabrade Air Lube or equivalent.)

5. Install 01476 Cylinder so it rests against the 01478 Front Bearing Plate, (make sure inlet holes of cylinder line up with inlet holes in

02676 Rear bearing Plate).

6. Press 02696 Bearing into 02676 Rear Bearing Plate. Press this assembly onto rotor. Important: Fit must be snug between bearing plates

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

snug fit. A loose fit will not achieve the proper preload of motor bearings. Next, place a small amount of grease on the 02696 Bearing and

stick the 02679 Shield against the bearing.

Planetary Gear Assembly:

1. Press 54520 Bearing onto front end of 50786 Carrier until it seats. Install 54519 Gears with holes in 50786 Carrier and slide in 54472 Shafts

2. Slip 54468 Ring Gear over gears and press rear 54520 Bearing onto 50786 Carrier until there is a slight drag between the ring gear and the

two bearings.

3. Slide assembly into 53152 Gear Case aligning slots in 54468 Ring Gear with holes in gear case.

4. Install 50784 Lock Screw into 53152 Gear Case using #567 Loctite or equivalent. Install 53451 Adapter to 53152 Gear Case, torque 34

N•m/300 in. - lbs. (use a small amount of #567 Loctite

To Assemble Motor and Planetary Gear Housing:

1. Slip motor into housing making sure motor drops all the way into housing. Secure motor assembly in vise using 52296 Repair Collar.

2. Attach 53152 Gear Case with planetary gears installed onto housing, torque 34 N•m/300 in. - lbs. (Use a small amount of #567 Loctite

on threads.)

To Install Angle-Head to Motor Assembly:

1. Run 54527 Lock Ring tight against 53451 Adapter (Note: Left-hand thread).

2. Assemble 5456 Angle-Head Assembly by threading onto 53451 Adapter making sure 53450 Spine Drive engages into rear of 54541 Spindle

(engage as many threads as possible until proper orientation is achieved with throttle).

3. Secure 54560 Angle-Head Assembly by torquing 54527 Lock Ring 34 N•m/300 in. - lbs. against the 54547 Housing.

Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.

Note: Motor should operate at 3,200 RPM at 6.2 bar (90 PSIG). RPM should be checked with a tachometer.

Important: Before operating, place 2-3 drops of Dynabrade Air Lube (P/N 95842) directly into air inlet with throttle lever depressed. Operate

tool for 30 seconds to determine if tool is operating properly and to allow lubricating oils to properly penetrate motor. 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.
