CAUTION:
. Pross 4th and sth gears on the countershaft without
lubrication.
. When installing ilth and sth geafs, support the shaft
on steel blocks, and install the gears using a press.
. Install ilth and sth gear with a maximum pressure of
25.5 kN (2,600 ksf, 18,806lbf).
NOTE; Refer to page 13-74 for reassembly sequence.

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.

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.

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.
