lMate the needle bearing with the shaft or bearing sleeve
and gear, and check to see if rotation is smooth with no
binding, noise, or play.
l Check the needle bearing cage for possible
deformation.SYNCHRONIZER RING
l Check the clutch gear teeth for damage and breakage.
l Check the cone inside paper lining for damage, wear or
peeling.l Force the synchronizer ring toward the clutch gear and
check clearance “A”. Replace if the clearance is below the
limit.Limit: 0.5 mm
(.020 in.)
SYNCHRONIZER SLEEVE AND HUB
lMate the synchronizer sleeve with the hub and check to
see if they slide smoothly.
lCheck to see if the sleeve is free from damage at its inside
front and rear ends.
l Check the hub front and rear end faces (in contact with
each speed gear) for wear.
Caution
When replacement is necessary, replace the synchro-
nizer hub and sleeve as a set.
SYNCHRONIZER KEY AND SPRING
l Check the synchronizer key center protrusion for wear.
lCheck the spring for proper tension, possible deformation
and breakage.

SERVICE POlNTS OF REASSEMBLY18. INSTALLATION OF SUB
GEAR/17. CONE SPRING/16. SNAP RING
Install the sub gear and cone spring to 3rd speed gear, andthen install the snap ring.
NOTE
Be sure that the cone spring is installed so that it is facing inthe correct direction.
10. INSTALLATION OF SYNCHRONIZER SPRINGS
(1) Install the synchronizer spring so that its protrusion fits
into the groove in synchronizer key. Make sure that the
protrusions in the front and rear springs are not in the
in,groove of the same key.
9. INSTALLATION OF
3RD-4TH SPEED SYNCHRONIZER
ASSEMBLY
(1) Install the synchronizer assembly so that the part that
has the small round indentation is in the oil groove at
the hub end.
NOTEIf the installation is in the opposite way, press-in might
not be possible. This is because the edge of the hub
inner diameter
spline at the part that has the small
round indentation is made to facilitate pressing in.
(2) Using the special tools, press-fit the
3rd-4th speed
synchronizer assembly over the input shaft.
Caution
1. When installing the synchronizer assembly,
make sure that the three synchronizer keys are
seated correctly in their respective grooves in
the synchronizer ring.
h2. After installing the synchronizer assembly, --
check to see if the
3rd speed gear rotates
smoothly.

Using the special tool, press-fit the bearing sleeve.
4. INSTALLATION OF TAPER ROLLER BEARING
Using the special tools, press-fit the bearing over the input
shaft.Caution
Apply the special tool to the inner race only when
installing the bearing.
3. INSTALLATION OF SNAP RING
(1) Select the thickest snap ring that fits in the snap ring
groove.Standard value:
0.01-0.09 mm (.0004-.004 in.)
(2) Using the special tool, fit the snap ring to the input
shaft.
NOTE
(I) Do not reuse the snap ring.
(2) The use of snap ring plier can cause the snap ring toexpand too much, making correct installation of the
sleeve difficult.

-‘d ’Caution
When the sleeve has been press-fitted over the input
shaft, make sure that the sleeve flange is in tight
contact with the bearing.
