Mainshaft Thrust Clearance Adiustment
Special Tools Required. Mainshaft base 07GAJ-PG20130. Mainshaft holder 07GAJ-PG20110

Installthe 3rd/4th synchro hub (A), the distance
collar (B), the 5th synchro hub {C). distance collar
(D), and ball bearing (E) on the mainshaft (F), then
installthe assembled mainshaft in the transmission
housing (G).
lnstall the washer (H) on the mainshaft.
Measure distance O between the end of the
transmission housing and washer with a straight
edge and vernier caliper. Measure at three
locations and average the reading.
5.Measure distance @ between the end of the clutch
housing (A) and the bearing inner race (B)with a
straight edge and depth gauge. Measure at three
locations and average the readings.

Shim Selection Formula:
6, Select the proper 72 mm shim from the chan.
Follow the example below, and use the
measurements you made in steps 4 and 5:
(Basic Formula)
O+@ (0.8 * 0.11) = shim thickness (maximum)
O + O (0.8 + 0.17) = shim thickness (minimum)
. Add distance O (step 5) to distance O (step 4)
. 0.8 mm (0.031 in): Spring washer, a dimension in
the installation.. 0.11 mm (0.004 in): lvlinimum thrust clearance
. 0.17 mm (0.007 in): Maximum thrust clearance.
(For example)
2.32 + 0.15 - (0.8 + 0.11)= 1.56 mm (0.061 in.)
2.32 + 0.15 - (0.8 + 0.17)= 1.50 mm (0.059 in.)
Take the middle value of the minimum value and
the maximum value, and select the 1.53 mm
(0.060 in.) shim.
