INSPECT - Continued.
k.
Check fit of gudgeon pin (105) in piston by
inserting gudgeon pin into piston (98).
l.
If gudgeon pin fits loose in piston, remove
gudgeon pin and measure outer diameter of
gudgeon pin Surface N with an outside
micrometer (Item 16, Appendix D).
m.
Outer diameter of gudgeon pin Surface N must
be 1.4998 to 1.5000 in. (38,095 to 38,100
mm).
n.
If outer diameter of gudgeon pin (105) is within
tolerance, replace piston.
o.
If outer diameter of gudgeon pin is less than
1.4998 in. (38,095 mm), replace gudgeon pin.
p.
Visually inspect piston (98) for cracks, grooves
or missing material. If cracks, grooves, or
missing material are detected, replace piston.
q.
Use a slide caliper to measure inside diameter
Surface O of sleeve bushing bore of
connecting rod assembly (99). Inside diameter
of bore Surface O must be 1.37575 to 1.37650
in. (34,9440 to 34,9631 mm).
r.
If inside diameter of bore is greater than
1.37650 in. (34,9631 mm), replace connecting
rod assembly. Refer to step E.6.
