17. Wipe a thin film of light grease on End Plate Gasket
(28) and press Gasket firmly
18. Insert protruding end of guide rod into dowel hole in
bore of Motor Housing and slide
19. Remove guide rod and replace it with Cylinder Dowel
(23).
20. Reposition Motor Housing in vise so that open face of
Motor Housing is upward.
21. Place two Motor Clamp Washers (29), convex side
first, against Front End Plate so
22. Place Rear Hammer Frame Washer (32) over hub of
Rotor and against Front Rotor.
For proper performance, the Cylinder (22) must be
installed according to the following instructions:
23. One end of the Cylinder has a small dimple on the air

(Dwg. TPA1778)
Set the Cylinder over the Rotor and onto the Front
End Plate.
24. Slide Rear End Plate and Bearing onto rotor hub and
against Cylinder.
25. Install Rear Rotor Bearing Retainer (21) in groove on
rotor hub.
26. Align dowel hole in both End Plates with the one
through Cylinder, and insert a guide rod 5/32”
diameter x 6” long (3.9 mm diameter x 152 mm
long). Allow rod to protrude from Rear End Plate.
27. Grasp handle of the Motor Housing in
leather--covered or copper--covered vise jaws so that
bore of the Motor Housing is horizontal.
28. Wipe a thin film of light grease on End Plate Gasket
(28) and press Gasket firmly against Rear End Plate.
29. Insert protruding end of guide rod into dowel hole in
bore of Motor Housing and slide motor along rod
until it is completely seated.
30. Remove guide rod and replace it with Cylinder Dowel
(23).
31. Reposition Motor Housing in vise so that open face of
Motor Housing is upward.
32. Place two Motor Clamp Washers (29), convex side
first, against Front End Plate so that inner rim of
leading Washer contacts End Plate, and outer rim of
trailing Washer contacts Hammer Case Pilot (35B).
33. Place Rear Hammer Frame Washer (32) over hub of
Rotor and against Front Rotor Bearing.
