Assembly/Disassembly Instructions
(continued)
3,200 RPM Angle Head Tools
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.
