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-11J). 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.
N O TE: 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 greater recess depth.
Extension Oil Seal or Bushing
If bushing in rear of extension requires replacement,
remove seal and use Tool J-5778 to drive bushing into
extension housing (Fig. 7B-12J). Using the same tool, drive
new bushing in from the rear. Coat I.D. of bushing and seal
with transm ission lubricant, then install new oil seal using
Tool J-5154 (Fig. 7B-13J).
