To Assemble Motor:

1. Press a 01009 Pin into face of 54511 Bearing Plate and 54516 Bearing Plate and Press 01042 Pin in outer

diameter of 54516 Front Bearing Plate.

2. 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.

3. Insert .002 Shim in 54516 Front Bearing Plate.

4. Insert 02649 Bearing into 54516 Bearing Plate.

5. Assemble 54515 Spacer onto pinion end of 54513 Rotor, making sure that the countersink faces the rotor.

6. Assemble 54516 Front Bearing Plate onto rotor by pressing on the inner race of 02649 Bearing and by supporting

rotor on opposite end. Be sure that bearing is pressed tight against 54515 Spacer.

7. 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.

8. Assemble 54512 Cylinder so that inlet part will align with inlet holes in 54511 Rear Bearing Plate. The cylinder

exhaust slots must align with the slots in the bearing plate.

9. Insert 54514 Blades (lubricate blades with Dynabrade Air Lube P/N 95842 or equivalent prior to installation).

10. Support assembly squarely on the pinion end of rotor. Place 11016 Bearing in 54511 Rear Bearing Plate and

press onto rotor, pressing on the inner race of 11016 Bearing, just enough to bring the bearing plate against the

cylinder. There should be a slight drag between the bearing plates and cylinder when these are moved with the

fingers. Position cylinder until motor turns "finger free".

To Assemble Motor in Housing:

(Note: Be sure that 01040 Lock Screw has been removed from motor housing).

1. Insert motor into 54509 Housing, making sure that 01042 Pin in 54516 Front Bearing Plate enters into slot cut into housing.

2. Insert 54517 Spacer with unrelieved face toward 54516 Front Bearing Plate.

To Assemble Planetary Assembly:

1. Press 54520 Bearing onto front end of 54521 Carrier until it seats.

2. Make sure that assembled 01033 Needle Bearing and 54519 Gears are lined up with hole and slide 54518 Shafts

into 54521 Carrier and 54519 Gears until end of shaft is flush with carrier face.

3. Place 54522 Gear, notches are to face rear end of the 54521 Carrier.

4. Press 54520 Bearing onto 54521 Carrier until there is a slight drag between the ring gear and the two bearings.

To Install Planetary Assembly in Housing:

1. Insert planetary assembly into motor housing, keeping notches in ring gear lined up with threaded hole for 01040 Lock Screw.

2. Thread lock screw into 54509 Motor Housing. Turn lock screw down until snug. Then back off 1/2 turn.

3. Thread 54526 Adapter onto 54509 Motor Housing.

To Assemble Angle-Head Assembly to Planetary Motor Assembly:

1. Assemble by screwing 54547 Angle Housing onto 54526 Adapter with 54527 Lock Ring.

2. Adjust and make certain that spline in 54541 Carrier is properly inserted into spline in 54541 Spline Spindle. Test

assembly at reduced speed, and secure assemblies with 54527 Lock Ring.

Tool assembly is complete

Note: Motor should operate at 3,200 RPM at 6.2 bar (90 PSI). RPM should be checked with a tachometer. Before operating, we recommend

that 2-3 drops of pneumatic tool oil be placed directly into the air inlet with throttle lever depressed. Grease gears through grease fittings.

Important

The regular maintenance of any air tool will contribute to greater efficiency of tool and will prolong tool life. The failure of quality

pneumatic air motors can most often be traced to an unclean air supply or the lack of lubrication. Air pressure easily forces dirt or water

contained in the air supply into motor bearings causing early failure. It often scores the cylinder walls and the rotor blades resulting in

limited efficiency and power. Frequent drainage of water traps in air lines is recommended. Each tool on each drop should also be

equipped with a secondary air processing unit. This consists of an in-line Filter-Regulator-Lubricator. All Dynabrade air tools must be

used with a Filter-Regulator-Lubricator to maintain all warranties. Our warranty obligation is contingent upon proper use of our tools and

cannot apply to equipment which has been subject to misuse such as unclean air, wet air or a lack of lubrication during the use of the tool.

Notice: Manufacturer's warranty is void if tool is disassembled before warranty expires.
