paper.
c. Press bushings (50) into housing (45) and cover (35).
d. Press new bearings (51) onto worm (43) shaft. Slide the worm into the housing (45) making certain the splined
end is on the motor side.
e. Install keys (52) in shaft (30) and press on new gear (46).
f.
With the housing (45) lying flat, position the thrust ring (47) over the bushing (50). Slide the shaft (30) through
the thrust ring and into the bushing. The worm will have to be moved to one side to provide adequate clearance
for the worm gear (46). Aline the teeth of the gear with the worm.
g. Start both bearing cups (44 and 48) into position with a plastic hammer.
h. Position the bearing retainer (41) and gasket (42) on the housing (45). Install screws (39) and washers (40) and
tighten them to press the bearing cup (44) into position. Tighten each screw about two turns then tighten another
screw until all are tight.
i.
Position bearing container (26) and gaskets (27) on housing. If the friction disc (28) was removed, glue a new
disc to container using a good quality high-temperature glue.
j.
If the rotor assembly (18) was disassembled, assemble the rotor assembly as follows:
(1)
Place the race (21) on a flat surface.
(2)
Install a screw type ring compressor loosely around the driver (25). Install the springs (24), plungers (23)
and rollers (22) in the driver. The plunger must be inserted in the hole of the driver before the ring
compressor is tightened. Tighten ring compressor.
(3)
Position the assembled driver over the race (21) and push the driver into the race. Work slowly and keep
the rollers (22) in position with respect to the driver (25).
k.
Slide the rotor assembly (18) over the shaft of worm (43).
l.
Tighten adjustment nut (8) on the spring assembly (9). Install gasket (7) and o-ring (6) on the adjustment nut (8)
and install spring assembly in the brake housing (4).
m. Slide the pressure plate (16) into the brake housing (4). The "ears" on the pressure plate fit in the detent inside
the brake housing. The ends of the spring assembly
