Valve Stem-to-Guide Clearance\
Inspection
1.Remove the valves (see page 6-3'1).
Slide the valve out of its guide about 10 mm. then
measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust (wobble method).. lf the measurement exceedsthe service limit,
recheck it using a new valve.. lf the measurement is nowwithin the service
limit, reassemble using a new valve.. lf the measurementwith a newvalve still
exceeds the service limit, go to step 3.

Service Limit: 0.22 mm 10.009 in.)
Subtract the O.D. of the valve stem. measured with
a micrometer, from the LD. of the valve guide,
measured with an inside micrometer or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide.
The difference between the largest guide
measurement and the smallest stem measurement
should not exceed the service limit

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.

11. Lower the transmission housing the rest of the wayas you expand the 72 mm snap ring {C). Release
the snap ring so it seats in the groove of the
countershaft bearing.
