Important: Manufacturer's warranty is void if tool is disassembled before warranty expires.
Motor Disassembly:
1. Disconnect tool from power source.
2. Secure air tool in soft jaw.
3. Remove drill chuck from rotor by inserting a 3/16" hex key through the chuck and into the end of the rotor shaft.
4. Use an adjustable pin wrench or 50971 Lock Ring Tool to remove 04102 Lock Ring by turning it counter-clockwise. Remove 04078 Felt Silencer and
air control ring.
5. Pull motor assembly from housing and fasten a bearing separator around the end of the cylinder nearest the 01244 Rear Bearing Plate.
6. Place bearing separator on the table of a (#2) arbor press and push the rear rotor shaft out of the rear motor bearing. Note: A 3/16" diameter flat nose
drive punch can be used as a press tool.
7. With cylinder and blades removed, secure the rotor body in a soft jaw vise and remove 04081 Rotor Nut, turning it counter-clockwise.
8. Press 01015 Rear Bearing out of 01244 Rear Bearing Plate with 96211 Bearing Removal Tool.
Motor Disassembly Complete.
Valve Disassembly:
1. Position motor housing in vise by holding on wrench flats, and with air inlet facing up.
2. Secure 01494 Inlet Adapter with a wrench and remove air fitting. Also, remove 01494 Inlet Adapter.
3. Remove 53190 Block Plate and 96065 O-Ring.
4. Remove 01468 Spring, 01472 Tip Valve and 01464 Seal.
5. Use a 2.5 mm drive punch to remove 01017 Pin and throttle lever from housing.
6. Remove 95558 Retaining Ring with external ring pliers and push 01247 Regulator from housing.
Valve Disassembly Complete.
Motor Assembly:
Important: Be sure parts are clean and in good repair before assembly.
1. Place rotor in soft jaw vise with a threaded spindle pointing up.
2. Slip 01010 Spacer onto rotor.
3. Place a .002" shim into front bearing plate as an initial spacing and slip 01007 Bearing into plate.
Note: 01121 Shim Pak contains .001" and .002" shims.
4. Install bearing/bearing plate assembly onto rotor.
5. Install 04081 Rotor Nut onto rotor (torque to 17 N•m/150 in. - lbs.).
6. 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 shim if necessary.
7. Once proper rotor/gap clearance is achieved, install well lubricated 01011 Blades (4) into rotor slots. Dynabrade air lube P/N 95842 is
recommended for lubrication.
8. Install cylinder over rotor. Be sure air inlet holes of cylinder face away from front bearing plate.
9. Press 01015 Rear Bearing into 01244 Rear Bearing Plate. Press bearing/bearing plate assembly onto rotor. Be sure that 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. 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.
10. Secure motor housing in padded vise so motor cavity faces upwards.
11. Install motor assembly into housing, making sure motor drops all the way into housing.
Note: Align the rear bearing plate node with the notch inside the housing.
12. Insert air control ring and 04078 Felt Silencer into 04102 Lock Ring and install onto motor housing (torque 34 N•m/300 in. - lbs.).
13. Motor adjustment can now be checked. With motor housing still mounted in vise, pull end of rotor and twist (10-15 lbs. force), rotor should turn
freely 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 shim.
Valve Body Assembly:
1. Insert 01247 Speed Regulator Assembly with o-rings into valve body. Secure with 95558 Retaining Ring.
2. Secure valve body in vise with air inlet pointing up.
3. Insert 01464 Seal into housing.
4. 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).
5. Install 96065 O-Ring onto 53190 Block Plate.
6. Install 53190 Block Plate into housing.
7. Apply Loctite
®
#567 PST Pipe Sealant to threads of 01494 Inlet Adapter and install onto valve body (torque 23 N•m/200 in. - lbs.).
8. Install 57342 Throttle Lever and 01017 Pin.
Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.
Important: Motor should now be tested for proper operation at 90 PSIG. 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 l.ever depressed. Operate tool for 30 seconds to determine if tool is operating properly and to allow lubricating oils to properly penetrate motor
