Refer to step D.9 for serviceable wear limits.
1.
INSPECT IDLER GEAR BUSHING FOR WEAR.
a.
Use a slide caliper (Item 20, Appendix D) to
measure inside diameter of Surface A of idler
gear (38) bushing.
b.
Inside diameter of idler gear (38) bushing must
be 1.9998 to 2.0007 in. (50,79 to 50,82 mm).
c.
If inside diameter of idler gear bushing
exceeds 2.0007 in. (50,82 mm), replace idler
gear.
d.
Use an outside micrometer (Item 16, Appendix
D) to measure width of Surface B of idler gear
(38) bushings.
e.
Idler gear bushing width must be 1.1865 to
1.1875 in. (30,14 to 30,16 mm).
f.
If idler gear bushing width is less than 1.1865
in. (30,14 mm), replace idler gear.
2.
INSPECT IDLER GEAR HUB FOR WEAR.
a.
Use an outside micrometer (Item 16, Appendix
D) to measure outside diameter C of idler gear
hub (142).
b.
Outside diameter of idler gear hub must be
1.9610 to 1.9975 in. (49,809 to 50,736 mm).
c.
If outside diameter of idler gear hub (142) is
less than 1.9610 in. (49,809 mm), replace
