REPAIRS
CLUTCH KEYS AND SPRINGS
Replacement
NOTE: The clutch hubs and sliding sleeves are selected
assembly and should be kept together as originally
assembled, but the keys and two springs may be replaced
if worn or broken.
1. Mark hub and sleeve so they can be matched upon
reassembly.
2. Push the hub from the sliding sleeve, the keys and the
springs may be easily removed.
3. Place the three keys and two springs in position (one
on each side of hub), so all three keys are engaged by both
springs (Fig. 7B-28). The tanged end of each synchronizer
spring should be installed into different key cavities on either
side. Slide the sleeve onto the hub aligning the marks made
before disassembly.
NOTE:
A
groove around the outside of the synchronizer
hub identifies the end that must be opposite the fork slot
in the sleeve when assembled. This groove indicates the
end of the hub with a .Oi" greater recess depth.
