INSPECTION AND REASSEMBLY
1) Clean all components thoroughly, inspect them for any
abnormality and replace with new ones as necessary.
2) If synchronizer parts need to be repaired, check clearance
“a” between ring (2) and gear (1), each chamfered tooth of
gear, ring and sleeve, then determine parts replacement.
Clearance between synchronizer ring and gear
Standard “a” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “a” : 0.5 mm (0.019 in.)
3) To ensure lubrication, air blow oil holes (1) and make sure
that they are free from any obstruction.
4) Fit high speed synchronizer sleeve (4) to hub (3), insert 3
keys (2) in it and then set springs (1) as shown in figure.
Synchronizer key installation position
: A = B
5) Drive in right bearing (1) to input shaft (2) by using special
tool and hammer.
Special tool
(A) : 09913-80112
NOTE:
 No specific direction is assigned to each key but it is
assigned as sleeve & hub assembly.
 Size of high speed synchronizer sleeve, hub, keys and
springs is between those of low speed and 5th speed
ones.

CAUTION:
To prevent 5th gear spacer from being distorted because
of excessive compression, do not press-fit it with left
bearing at once.
