Procedure

Check sprocket teeth for wear by

looking at undercut on sprocket (un-

dercut is located on two teeth).

Sprocket teeth are excessively worn

if wear has reached bottom of under-

cut.

If sprocket is not equipped with un-

dercut indicators, use wear gage

(Item 28, Chapter 3, Section I) to

measure wear on driving side of

sprocket teeth. If sprockets have

been reversed, use side “B” of gage.

If not, use side “B” of gage. Place

wear gage over two mounting bolts

and check for wear. Sprocket teeth

are excessively worn if wear has

reached bottom of any notch on

gage.

If sprocket teeth are excessively

worn, reverse or replace sprocket

(page 14-72).
