Cou ntershaft lnspection
1. Inspect the gear surface and bearing surface for
wear and damage, then measure the countershaft
at points A, B, and C. lf any part of the countershaft
is less than the service limit, replace it with a new
one.
Standard:
A Ballbearing surface ltransmission housing sidel:
30.020 -30.033 mm {1.1819 1.1824in.)

C Needle bearing surface (clutch housing side):
35.000 35.015 mm {r.3780-1.3785 in.)
Service Limit:
A: 29.97 mm {1.180 in.)
B: 39.88 mm {1.570 in.l
C: 34.95 mm {1.376 in.)
lnspect the runout by supporting both ends of lhe
countershaft. Rotate the countershaft two complete
revolutions when measuring the runout. lf the
runout exceeds the service Iimit, replace the
countershaft with a new one.
Standard: 0.02 mm (0.001 in.) max.

Mainshaft Thrust Clearance Adiustment
Special Tools Required. Mainshaft base 07GAJ-PG20130. Mainshaft holder 07GAJ-PG20110
1. Remove the 72 mm shim (A) and oilguide plate M
from the transmission housing (B).

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.
