INSPECTION PROCEDURES &
SECTION V-B
TORQUE SPECIFICATIONS
Inspection
Prior to reassembling the mainshaft, certain individual
parts should be examined. Parts damaged from
previous
service
should
be
eliminated
to
insure
maximum rebuild life.
We
strongly
suggest
following
these
inspection
procedures:
Synchronizers: Both the internal and external teeth
must have sharp edges. Rounded corners or excessive
chipping will cause gear jumping. Also, examine
synchronizer rings for metal contamination.
Gears: Examine gears for broken or cracked operating
teeth. Also, check for any unusual wear patterns.
Clutching teeth must not show excessive wear.
Thrust Washers: Check for flatness or excessive face
wear, cracks or scoring.
Snap Rings: Examine these for distortion or loss of
tension. We recommend using new snap rings with
every rebuild. During installation, assemble snap rings
with the die rolled side toward the needle bearing cage
where applicable.
Mainshaft: Check clutch gear spline gear locks for
sharp corners. Worn or ironed-out gear locks will
produce gear jumping. Also, check for chipped splines
at snap ring grooves. Apply a coat of moly grease to all
bearings.
