Standard:

0.20-0.60 mm
(0.008-0.023 in)

Service Limit:

0.60 mm
(0.023 in)


2.

Measure the width of the reverse shift fork.


If the width is not within the standard, replace the reverse shift fork.

If the width is within the standard, replace the reverse idler gear.


Standard:

14.7-14.9 mm
(0.579-0.587 in)
