Reverse Shift Fork Clearance
Inspection
1. Measure the clearance between the reverse idler
gear {A) and the reverse shift fork (B) with a feeler
gauge (C). lf the clearance is more than the service
limit, go to step 2.
Standard: 0.20-0.59 mm (o.oo7 0.024 in.l
Service Limit: r.3 mm {0.051 in.)
Measu re the width of the reverse shift fork.
. lf distance is notwithinthestandard, replacethe
reverse shift fork with a new one.. lf distance is within the standard, replacethe
reverse gear wrln a new one.
