Drive Clutch Reassembly
NOTE: It is important that the same number and
thickness of washers are reinstalled beneath the
spider during assembly. The Teflon bushings are
self-lubricating. Do not apply oil or grease to the
bushings.
Reassemble drive clutch in the following sequence. Be sure the
“X”, or the marks that were made earlier, are aligned during
each phase of assembly.
A) “X”, or the marks that were made earlier on cover
B) “X” on spider, making sure spacer washers are installed
underneath spider and positioned properly in recess
C) “X”, or the marks that were made earlier under weight
1. Install moveable sheave onto fixed sheave.
2. Install spider spacers. Use same quantity and thickness as
were removed.
3. Compress spider buttons for each tower and install spider
towers on the moveable sheave. Verify that the alignment
marks on spider align with the marks that were made on the
moveable sheave.
4. Torque spider to specification using the holding fixture and
spider tool. Torque with smooth motion to avoid damage
to the stationary sheave.
