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. Do not installthe
synchro sleeve with its longer teeth in the lsv2nd syn-
chro hub slots because it will damage the spring ring.

Reassembly (cont'd)
Remove transfer cover A.
lf the measurement is out of specification, remove
the 68 mm thrust shim from transfer cover A by
heating the cover to almost 212'F (100'C) using a
heat gun. Do not heat the cover higher than 212F
(100"C). Let the cover cool to room temperature
before adjusting the starting torque.

Select the proper 78 mm shim from the chan by
using the formula below.
Shim S€lection Formula:
From the measurements you made in steps 4 and 5:-1. Add distance @ (step 5) to distance @ (step 4).
-2. From this number. subtract 0.93 (which is the
midpoint of the flex range of the clutch housing
bearing spring washer).
-3. Take this number and compare it to the avail-
able shim sizes in the chart.
(For example)
A: 2.39 2.61
+ Bi O.22 - 0.93
= 2.61= 1.68
Try the 1.68 mm (0.0661 in) shim.
