chronizer sleeve & hub assembly (1) with gear by using
press.
6) Disassemble synchronizer sleeve & hub assembly.
7) Take out needle bearing from shaft.CAUTION:
 Use puller and press that will bear at least 5 ton (11,000
lb) safely.
 To avoid tooth damage, support 4th gear at flat side of
puller.
CAUTION:
 If compression exceeds 5 ton (11,000 lb), release com-
pression once, reset puller support and then continue
press work again.
 To avoid gear tooth from being damaged, support it at
flat side of bearing puller.
