CLEANING AND INSPECTION

Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)

Clean all parts with solvent. Blow parts dry with low pres-
sure compressed air.

Check gear teeth for damage. If gears are pitted, scored,
rounded, cracked or chipped, they should be replaced.

Inspect the engaging dogs and pockets on the dog rings.
Replace the dog rings if dogs and/or pockets are rounded,
battered or chipped.

Inspect guiding hubs. Replace guiding hubs if splines are
rounded, battered or chipped.

Inspect shift fork shafts. Replace if bent or damaged.

Inspect shift forks for wear or signs of overheating.
Replace a shift fork if it is excessively worn or shows signs
of overheating.

See

Figure 7-24

. Using a small carpenter's square, verify

the shift forks are square. If shift fork does not rest directly
on the square, then it is bent and must be replaced.

Inspect shift drum and bearing. Replace shift drum
assembly if drum or bearing are damaged.

Clean shift cam lock plate mounting holes in transmission
bearing housing.

10. Inspect side door bearings. Bearings must rotate freely

without drag. Replace the bearings if pitted, grooved or if
the shafts were removed.

NOTES

•

Replace retaining ring and all gear roller bearings with
new parts during assembly. Lubricate needle bearings
and races with clean transmission lubricant before install-
ation.

•

Install securing segments so the side with the rounded
edge is facing up and the side with the straight edge is
down. Be sure segments fully engage grooves in counter-
shaft.

•

One side of the lock rings have a stepped face. The
stepped face always faces the securing segments.

Clean all parts in solvent except the transmission case
and needle bearings. Blow dry with compressed air.

NOTE

Never wash the transmission case and needle bearings with
solvent unless the needle bearings are to be replaced. Normal
cleaning methods will wash dirt or other contaminants into the
bearing case (behind the needles) and leads to bearing failure.

Inspect the main drive gear for pitting and wear. Replace
if necessary.

Inspect the needle bearings inside the main drive gear.
Replace the needle bearings if the mainshaft race is pitted
or grooved.
