To replace the friction shoes, remove the e-clips
that retain the backing plate. Use a suitable tool
to remove and install the springs connecting the
shoes, using care not to over-stretch the springs
more than is necessary.
To reassemble the driven assembly, reverse the
disassembly procedures. Fill the outer sheave
cavity with fresh grease and slide onto the inner
sheave shaft. Align and insert the (2) roller/pin
assemblies. Install new o-rings and the outer
roller pin cover. Place the washer onto the
threaded shaft and apply Loctite
TM
272 to the
threads.
Have an assistant available for final assembly.
Install the compression spring. Place the friction
pad assembly over the spring and compress the
driven assembly together with both hands. With
the assembly compressed and the threads
exposed, have an assistant thread a new retaining
nut onto the shaft. Secure the assembly in a
clamping device and torque the retaining nut to
50-54 ft lbs (68-73 Nm).
Inspect the surface of the drive belt for uneven
wear or grease deposits. Using a vernier caliper,
measure the width of the belt. The service limit
of the belt is 0.708” (18mm).
