DISASSEMBLY (REFER TO FIGURE 9)
1. Remove dust cap (5). Remove the cotter pin (1) from
the locknut (12). Remove the locknut (12) and washer
(9).
2. Remove the fan plate assembly and set aside.
3. Slide the piston housing (13) and piston (14) off the
shaft.
4. Separate the piston (14) from the piston housing (13)
and remove the o-ring (3).
5. Remove the o-rings (2 & 4) from the shaft.
6. Remove the pressure plate (6) and the six springs (7).
7. Disengage the lock tabs on lockwasher (17) and using a
1-9/16” socket, remove hex nut (16) and the lockwasher
(17).
NOTE: To fabricate a tool to remove the 1-9/16” hex nut,
take two deep sockets and cut the end out of one
and weld the remaining length onto the bottom of
the other socket to make it approximately double
the original length.
PULLEY DISASSEMBLY
1. Support the backside of the pulley so that the shaft
bracket assembly can be pressed down far enough to
remove the pulley assembly. Since the bearings are
originally installed with Loctite between the shaft and
bearings, a force as high as 5000 lbs. may be required
to remove the pulley assembly. The bearings will be
damaged after this point of disassembly and must be
replaced.
