Distance between lever end and shaft bore
“a” : 5 mm (0.2 in.)
CAUTION:
Take care not to damage oil seal lip by input shaft, or oil
leakage may take place.
NOTE:
Input shaft right bearing on shaft can be installed into
right case by tapping shaft with plastic hammer.

eter then mate it with left case (1).
“B” : Sealant 99000-31110
8) Tighten case bolts (3) from left case side to specified torque.

10) Install another case bolts from clutch housing side and
tighten them to specification. NOTE:
Distance “a” can be measured by installing reverse
gear shaft provisionally.
When “a” is 5 mm (0.2 in.), clearance between reverse
idler gear groove and shift lever end will be 1 mm (0.04
in.).
NOTE:
Make sure that washer (4) has been installed in shaft at
above the gear.
Check to confirm that reverse gear shift lever end has
clearance 1 mm (0.04 in.) to idler gear groove.
