for wear and damage, then measure the counter-
shaft at points A, B, and C. lf any parts of the coun-
tershaft are less than the service limit. reDlace coun-
torshaft with a new one.

Synchro Sleeve, Synchro Hub
Inspection
1,Inspect gear teeth on all synchro hubs and synchro
sleeves for rounded off corners. which indicates
Install each synchro hub in its mating synchro
sleeve and check for freedom of movement.
NOTE: lf replacement is required, always replace
the synchro sleeve and synchro hub as a set.
Installation
When assembling the synchro sleeve and synchro hub,
be sure to match the three sets of longer teeth (120
degrees apart) on the synchro sleeve with the three sets
of deeper grooves in the synchro hub.
CAUTION: Do noi install tho synchro sleeve with its
longer toeth in the synchro hub slots, because it will
damage the spring ring.

D: Inspect the gear hub thrust surface for wear.
E: Inspect the cone surface for wear and roughness.
F: Inspect the teeth on all gears for uneven wear,
scoring, galling, and cracks'
2. Coat the cone surface of the gear with oil, and place
the synchro ring on the matching gear. Rotate the
ring, making sure that it does not slip
Measure the clearance between the synchro ring
and gear allthe way around.
NOTE: Hold the synchro ring against the gear even-
ly while measuring the clearance.

NOTE;
. Use a straight edge and depth gauge.. Measure at three locations and average the read-ings.
Select the prcpet 72 mm thrust shim from the chartby using the formula below.
NOTE: Us€ only one 72 mm thrust sntm.
Shim Selection Formula:
From the measurements you made in steps 4 and 5:. Add distance O lstep 5) to distance @ (step 4).
. From this number, subtract 0.93 (which is themidpoint of the flex range of the clutch housingbearing spring washer).
. Take this number and compare it to the availableshim sizes in the chart.
