SERVICE POINTS OF REASSEMBLY
13. INSTALLATION OF SYNCHRONIZER SPRINGAssemble the synchronizer spring so that its projection
may be engaged in the groove of the synchronizer key.
Take care to prevent the projections of the front and rear
spring from sitting in the groove of the same key.
12. 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) Press the
3rd-4th speed synchronizer assembly onto
the input shaft using the special tool as illustrated.
Caution
When installing the synchronizer assembly, make
sure that three synchronizer keys are seated cor-rectly in respective grooves of the synchronizer
ring.(3) Check the
3rd speed gear rotates smoothly.
10. INSTALLATION OF BEARING SLEEVEUse the special tool as illustrated.
