Disassembly/Assembly Instructions - .5 Hp/7°/Front Exhaust
Important: Manufactures warranty is void if tool is disassembled before warranty expires.
Please refer to parts breakdown for part identification.
To Disassemble:
1. Secure air tool in a vise equipped with aluminum or bronze jaws.
2. Remove collet cap and insert.
3. With an adjustable pin wrench or 50791 Lock Ring Wrench, remove 04087 Lock Ring by turning counter-clockwise. Remove air control
silencer and fabric silencer.
4. Pull motor assembly from housing.
5. Reposition motor housing in vise so inlet bushing is pointing up.
6. Unscrew 01494 Inlet Bushing turning counter-clockwise.
7. Using needle nose pliers, remove 01468 Spring, 01472 Tip Valve and 01464 Seal.
8. Resecure housing in vise so throttle lever and 12132 Pin are accessible.
9. Using a 2.5mm diameter drift pin and a hammer, remove 12132 Pin from housing and remove throttle lever.
10. Remove 95558 Retaining Ring and push 01469 Speed Regulator from Housing.
Optional: To disassemble valve body from motor housing, peel back 01558 Collar to expose 01462 Lock Nut. Unscrew lock nut/valve body from housing
(left hand threads).
Motor Disassembly:
1. Remove 50011 Collet Body from rotor shaft by inserting 3/16" hex wrench through collet body and into rotor shaft. Twist collet body from shaft.
2. Remove 01008 Front Bearing Plate, cylinder, blades (4) and 01149 Spacer from rotor.
Note: 01007 Bearing, 01008 Front Bearing Plate and 01149 Spacer are a slip fit onto rotor.
3. Press rotor from 01015 Rear Bearing. Press 01015 Bearing from 01014 Rear Bearing plate.
Motor Disassembly Complete.
Motor Assembly
Important: Be sure parts are clean and in good repair before assembling.
1. Place rotor in padded vise with a threaded spindle facing upwards.
2. Slip 01010 Spacer onto rotor.
3. Place a .002" shim into 01008 Front Bearing Plate as an initial spacing (Note: 01121 Shim Pack contains .001" and .002" shims) and slip 01007
Bearing into plate.
4. Install Bearing/Bearing Plate assembly onto rotor.
5. Tighten 50011 Collet Body onto rotor (torque to 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 bearing plate.
9. Press 01015 Rear Bearing into 01014 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. Be sure motor drops all the way into housing.
12. Insert air control silencer and fabric silencer into 04087 Lock Ring and install onto motor housing (torque 150 in. - lbs.).
13. Motor adjustment must 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 Stem/Body Assembly:
1. Insert 01469 Speed Regulator Assembly into valve body. Secure with 95558 Retaining Ring.
2. Secure valve body in vise with air inlet facing up and throttle lever accessible.
3. Insert 01464 Seal into housing.
4. Line-up the hole in the 01449 Valve Stem with the hole in the housing (looking past brass bushing). Using needle nose pliers, insert 01472 Tip Valve so
that the metal pin passes through the hole in the valve stem.
5. Install 01468 Spring (small end towards the tip valve).
6. Apply a small amount of #567 Loctite (or equivalent) to threads of 01494 Inlet Bushing and install into valve body (torque 23 N•m 200 lbs. in.).
7. Install throttle lever and 12132 Pin. Remove valve body from vise.
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.
Note: Throttle lever is preset at the factory at an 11:00 o'clock position.
