15. Coat each Vane (23) with a thin fi lm of oil and insert a Vane
into each of the rotor vane slots with the straight edge of Vane
outward.
16. Install the Cylinder (20) over the Vanes and Rotor. Make certain
the contour at the end of the Cylinder matches the contour of the
End Plate. Make certain the Cylinder Alignment Pin (21) enters the
hole in the face of the End Plate.
17. Place the Rear End Plate and Bearing against the face of the
Cylinder, Bearing end trailing. Make certain the Cylinder
Alignment Pin enters the hole in the End Plate.
18. Insert the assembly, Rear End Plate leading, into the Motor
Housing making sure the End Plate Alignment Pin (25) enters the
notch in the Housing.
It may be necessary to tap the assembly into position with a brass
of plastic hammer. (Refer to Dwg. TPD1303).

Assembly of the Impulse Mechanism
1. Insert the long shaft of the Spring Guide (41) into the central
opening of the O-ring Installer furnished with the Tool Kit (Part
No. 180PQ-99 or Part No. 700A-99). Place the Spring Guide Seal
(46) on the tapered end of the installer and roll the Seal up the
taper and into the groove on the large body of Spring Guide.
For Model 700A, repeat the procedure with the second Spring
Guide and Seal. (Refer to Dwg. TPD 1305)

For Model 700A, when looking inside the central opening of the
Linder (42), the internal wall has three holes on one side which do
not extend through the wall. The opening on the end face of that
wall is for the Relief Valve (44). Install the Relief Valve, large end
trailing, into that opening. Insert the Guide Assist Spring (47) into
the hole in the end face of the opposite wall.
3. For Model 700A, insert a Spring Guide Assembly, large end
trailing, into the opening against the Relief Valve. Mark this
opening with a felt marker to indicate that it contains the Relief
Valve. Install the remaining Spring Guide Assembly, large end
trailing, into the hole with the Spring.
4. For Model 500A, install the Liner Cover O-ring (40) in the groove
around the Rear Liner Cover (39).
For Model 700A, install the Rear Liner Cover Seal (41) in the
annular groove on the face of the Rear Liner Cover (39).
5. For Model 700A, install the two Front Liner Cover Guide Seals
(62) in the openings on the face of the Front Liner Cover (56).
6. For Model 500A, if the Oil Stop Cap Assembly (65) was removed
from the Front Liner Cover (54), install the Stop Cap O-ring (66)
and Back-up Ring (67) in the groove of the Cap and insert the

7. Insert the short round hub of the Drive Shaft (61) into the central
opening of the Rear Linder Cover.
8. For Model 500A, insert a Blade (49) into one slot in the Drive
Shaft with the Blade Assembly Pin (50) inward toward the Shaft.
Install the Blade Springs (51) through the Drive Shaft and encircle
the Pins in the Blade. Place the remaining Blade on the Springs
making certain the Springs encircle the Pins in that Blade.
For Model 700A, insert a Blade (49) into one slot in the Drive
Shaft. Install the Blade Springs (65) through the Drive Shaft and
into the holes in the Blade. Place the remaining Blade on the
Springs making certain the springs enter the holes in that Blade.
