9. Apply small amount of #567 Loctite®(or equivalent) to threads of 01494 Inlet Bushing and install into valve body.
(Torque 23 N•m/200 in. lbs.).
10. Install 01448 Throttle Lever and 12132 Pin. Remove valve body assembly from vise.
Motor Assembly:
1. Place 01120 Rotor in a padded vise.
2. Slip 01010 Spacer onto 01120 Rotor.
3. Place a .002 shim into 01008 Bearing Plate as an initial spacing (Note: 01121 Shim Packs contain .001 and .002 shims)
and slip 01007 Bearing into plate.
4. Install 01007, 01008 Bearing/Bearing Plate onto 01120 Rotor.
5. Tighten 04081 Rotor Nut onto 01120 Rotor, torque to 150 in. lbs.
6. Check the clearance between rotor and bearing 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/rate clearance is achieved, install well-lubricated 01011 Blades into 01120 Rotor. Dynabrade Air Lube P/N 95842
is recommended for lubrication.
8. Install 01013 Cylinder so it rests against the 01007 Bearing Plate. (Make sure that air inlet holes of cylinder are facing away
from 01007 Bearing Plate).
9. Press 01015 Bearing into 01014 Bearing Plate. Press these parts onto 01120 Rotor. Be sure that pin and air inlet holes in
bearing plate line-up with pin slot and air 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. Install motor assembly in housing, make sure motor drops all the way into housing. Line-up air inlet holes in 01014 Bearing
Plate with air inlet holes in housing.
11. Install exhaust control spacer, silencer and o-rings (if equipped) into lock ring. Install lock ring (small amount #567 Loctite
®
or
equivalent ) onto housing and torque to 34 N•m/300 in. lbs.
12. Motor adjustment must now be checked. With motor still mounted in vise, pull end of 01120 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 (see instructions
1–6). Also push end of 01120 Rotor and twist (10-15 lbs. force), rotor should turn freely without drag. If drag or rub is felt
then deload or add shim.
13. Motor should now be tested for proper operation at 90 PSIG. If motor does not operate properly, make necessary
adjustments (see step 12).
14. Install drive wheel. (Torque to 3.5 N•m/30 in. lbs.)
Housing Assembly: Non-Vacuum
1. Place 15307 Tension Shaft into housing.
2. Apply one drop of #242 Loctite

12. Complete assembly by installing contact arm assembly, abrasive belt and 40370 Belt Guard.
Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.
Note: Motor should operate at between 18,000 and 20,000 RPM at 90 PSIG (6.2 Bar). RPM should be checked with a
tachometer. Before operating, we recommend that 2-3 drops of Dynabrade Air Lube P/N – 95842 (or equivalent) be placed
directly into the air inlet with the throttle lever depressed.
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.
