Disassembly/Assembly Instructions - .4 Hp/Straight-Line/Rear Exhaust
Important: Manufacturer's warranty is void if tool is disassembled before warranty expires.
Notice: Dynabrade strongly recommends the use of their 52296 Repair Collar (sold separately) during assembly/disassembly activities. Failure to
use this collar will highly increase the risk of damage to the valve body of this tool. Please refer to parts breakdown for part identification.
Motor Disassembly:
1. Disconnect tool from power source.
2. Secure air tool in vise using 52296 Repair Collar.
3. With an adjustable pin wrench, remove 50781 Rear Exhaust Cover by turning counter-clockwise.
4. Remove 50784 Set Screw and pull 50782 Adapter and planetary carrier assembly from 50776 Housing.
5. Press planetary carrier assembly from rear 54520 Bearing. Remove ring gear and gears from 50786 Planetary Carrier.
6. Secure planetary carrier in vise and remove 50782 Adapter. Press carrier from front 54520 Bearing.
7. Grab onto pinion and pull motor assembly from motor housing.
8. Press 54554 Rotor from 02696 Rear Bearing. Press 02696 Rear Bearing from 02673 Rear Bearing Plate, remove 02679 Shield.
9. Remove cylinder and rotor blades from rotor.
10. Press rotor through 02649 Front Bearing and 01478 Front Bearing Plate.
Motor Disassembly Complete.
Valve Body Disassembly:
1. Position valve body in vise using 52296 Repair Collar 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 felt muffler.
5. Remove 01564 Air Control Ring from valve body. Using needle nose pliers, remove 01468 Spring, 01472 Tip Valve and 01464 Seal.
6. Remove 95558 Retaining Ring. Push 01469 Regulator from valve body and remove o-rings.
Disassembly Complete.
Motor Assembly:
Important: Be sure parts are clean and in good repair before assembling. Follow all grease, oil, and torque specifications.
1. To correct for bearing tolerances, it is necessary to use 54529 Shim Pack (as req.) to maintain correct clearance between ends of rotor and bearing plates.
2. Insert .002 Shim in 01478 Front Bearing Plate.
3. Insert 02649 Bearing into 01478 Bearing Plate.
4. Assemble 01479 Spacer onto pinion end of 54554 Rotor, making sure that the countersink faces the rotor.
5. Assemble 01478 Front Bearing Plate onto rotor by pressing on the inner race of 02649 Bearing and by supporting rotor on opposite end. Be sure that the
bearing is pressed tight against 01479 Spacer.
6. Hold rotor in left hand and the bearing plate in right hand. Apply an outward (pulling) pressure and observe spacing between end of rotor and bearing
plate. This should be from flush (not rubbing) to .002 maximum. If the rotor rubs the bearing plate, reduce the spacing between the bearing and the
bearing plate by removing the .002 shim entirely, or by substituting a .001 shim for the .002 shim. However, if there is more than .002 spacing between the
end of the rotor and bearing plate, add .001 shim between the bearing and the bearing plate.
7. Assemble 01476 Cylinder so that inlet part will align with inlet holes in 02673 Rear Bearing Plate. The cylinder exhaust slots must align with the slots
in the bearing plate.
8. Insert 01480 Blades (lubricate blades with Dynabrade Air Lube P/N 95842 or equivalent prior to installation).
9. Support assembly squarely on the pinion end of rotor. Press 02676 Bearing into 02673 Rear Bearing Plate and press these onto rotor, pressing on the
inner race of 02696 Bearing, just enough to bring the bearing plate against the cylinder. There should be slight drag between the bearing plates and
cylinder when these are moved with the fingers. Position cylinder until motor turns "finger free." Be sure that pin and air inlet hole in cylinder line up with
air inlet hole and pin hole in bearing plate.
10. Place 02679 Shield over 02696 Bearing.
11. Install motor assembly into motor housing.
12. Press front 54520 Bearing onto front end of 50786 Planetary Carrier.
13. Apply one drop of #271 Loctite
14. Install planetary gears and 54472 Gear Shafts onto planetary carrier.
15. Slip 54468 Ring Gear over gears and press rear 54520 Bearing onto planetary carrier.
16. Slip complete planetary carrier onto pinion in motor housing, so that notches in ring gear line-up with grease fitting and set screw. Install 50784 Set
Screw into housing.
17. Install 50781 Exhaust Cover onto 50776 Housing (torque 28 N•m/250 in. - lbs.).
Motor Assembly Complete.
Valve Body Assembly:
1. Insert 01469 Regulator with o-rings and valve stem in place into valve body. Secure with 95558 Retaining Ring.
2. Secure valve body in vise using 52296 Repair Collar with air inlet facing upward. Insert 01464 Seal.
