3. With an adjustable pin wrench, remove 53186 Planetary Housing by turning counter-clockwise.
4. Pull 53181 Adapter and first planetary carrier assembly from 53186 Planetary Housing.
5. Press planetary carrier assembly from rear 02552 Bearing. Remove ring gear and gears from 53180 Planetary Carrier.
6. Secure planetary carrier in vise and remove 53181 Adapter. Press carrier from front 02552 Bearing. Remove 53179 Spacer.
7. Grab onto pinion and pull motor assembly from motor housing.
8. Press 53178 Rotor from 01721 Rear Bearing Plate. Press 02649 Rear Bearing from rear bearing plate.
9. Remove cylinder and rotor blades from rotor.
10. Secure rotor in vise and remove pinion from rotor by inserting a 3mm drift pin through hole in pinion and twist off (right hand threads).
11. Press pinion and rotor through 53174 Front Bearing and 53171 Front Bearing Plate.
Motor disassembly complete.
Valve Body Disassembly:
1. Position valve body in padded vise with air inlet facing up.
2. Remove air fitting by securing 94523 Inlet Adapter with a wrench and twist air fitting from inlet adapter.
Important: 94523 Inlet Adapter must be secured before attempting to remove air fitting to avoid damaging valve body housing.
3. Remove 94523 Inlet Adapter.
4. Remove 95711 Retaining Ring from inlet adapter and separate 94521 Muffler Base from 94522 Muffler Cap. Remove sintered muffler and felt muffler.
5. Remove 01564 Air Control Ring from valve body. Using needle nose pliers, remove 01468 Spring, tip valve and seal.
6. Using a 2.5mm drift pin, tap 01017 Pin from housing and remove throttle lever.
7. Remove 95558 Retaining Ring. Push 01247 Regulator from valve body and remove O-rings.
Disassembly complete.
Motor Reassembly:
Important: Be sure parts are clean and in good repair before reassembly. Follow all grease, oil, and torque specifications.
1. Place 53171 Front Bearing Plate onto front end of 53178 Rotor (threaded end). Press 53174 Front Bearing onto rotor and front bearing plate.
2. Secure rotor in padded vise with threaded spindle facing up. Apply one drop of #271 Loctite® (or equivalent) to threads of rotor. Using a 3mm drift pin,
tighten pinion onto rotor (torque 17.0 N•m/150 in. - lbs.).
3. Apply one drop of #609 Loctite® (or equivalent) to outer race of 02649 Rear Bearing and slip bearing into bearing plate.
4. Install well lubricated blades into rotor slots. Dynabrade recommends using their 95842 Dynabrade Air Lube.
5. Install cylinder over rotor with air inlet hole in cylinder wall facing away from front bearing plate.
6. Press 01721 Rear Bearing plate on to rotor. Be sure that pin and air inlet hole in cylinder line up with air inlet hole and pin hole in bearing plate.
7. Install motor assembly into motor housing. Place 53179 Spacer on top of motor.
8. Press Front 02552 Bearing onto front end of first 53180 Planetary Carrier.
9. Install gears, 04026 Bearings and 53182 Gear Shafts onto planetary carrier.
10. Slip 53191 Ring Gear over gears and press rear 02552 Bearing onto planetary carrier.
11. Apply one drop of #271 Loctite® to threads of 53181 Adapter. Install adapter onto planetary carrier (torque 17.0 N•m/150 in. - lbs.).
12. Install 53186 Planetary Housing onto housing to secure motor (torque 28 N•m/250 in. - lbs.).
13. Roll back 53175 Collar and install abrasives.
Motor Reassembly Complete.
Valve Body Reassembly:
1. Insert 01247 Regulator with O-rings and valve stem in place into valve body. Secure with 95558 Retaining Ring.
2. Secure valve body in padded vise with air inlet facing upwards. Insert 01464 Seal.
3. Line up hole in valve stem with hole in housing (looking past brass bushing). Insert 01472 Tip Valve so that the metal pin passes through the hole in the
valve stem. Install 01468 Spring (small end towards tip valve).
4. Assemble sintered muffler and felt muffler together and place in 94522 Muffler Cap. Install 94521 Muffler Base onto muffler cap.
5. Install 95438 O-ring into groove on muffler base. Place 95375 O-Ring and 94526 Spacer into recessed area of muffler cap.
6. Slip 94523 Inlet Adapter through muffler assembly and install 95711 Retainer Ring into groove on inlet adapter.
7. Install 01564 Air Control Ring into valve body housing.
8. Apply Hernon #940 PST Pipe Sealant to threads of 94523 Inlet Adapter and install entire muffler assembly onto valve body (torque 23.0 N•m/200 in. - lbs.).
9. Replace air fitting. Secure inlet adapter with a wrench before tightening air fitting. Install throttle lever and 01017 Pin.
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 30 seconds to determine if tool is operating properly and to allow lubricating oils to properly penetrate motor
