When any of the outer ring,
inner ring or cone has to
be replaced, replace them as a set.

Check to ensure that the clutch gear tooth surface
and cone surface are not damaged and
broken.<Synchronizer ring set No.1>
|
|
2.Check to ensure that the
clutch gear tooth surface and cone surface are not damaged
and broken.<Synchronizer
ring No.2>
|
|
3.After applying oil to the
taper portion on each gear, press and fit the synchronizer
ring
by hand. Confirm the synchronizer ring cannot be
rotated.
|
|
4.Using the thickness gauge,
check the clearance between the synchronizer ring and the
gear.
