1. Measure the clearance between the reverse idler
gear (A) and the reverse shift fork (B) with a feeler
gauge (C). If the clearance exceeds the service limit,
go to step 2.
2. Measure the width of the reverse shift fork.  If the width is not within the standard, replace thereverse shift fork.
 If the width is within the standard, replace the reverse idler gear. 1. Measure the clearance between the change lever
(A) and the select lever (B) with a feeler gauge (C). If
the clearance exceeds the service limit, go to step
2.
2. Measure the groove width of the change lever.  If the groove width is not within the standard,replace the change lever.

1. Measure the clearance between each shift fork (A)and its matching synchro sleeve (B). If the
clearance exceeds the service limit, go to step 2.
2. Measure the thickness of the shift fork fingers.  If the thickness is not within the standard, replacethe shift fork.
 If the thickness is within the standard, replace the synchro sleeve and the synchro hub as a set.
 If one arm of the shift fork shows more wear than others, the fork may be bent and needs to be
replaced. 3. Measure the clearance between the shift fork (A)
and the shift arm (B). If the clearance exceeds the
service limit, go to step 4.
4. Measure the width of the shift arm.  If the width is not within the standard, replace theshift arm.
 If the width is within the standard, replace the shift fork or the reverse shift piece.
