Inspection
1.Inspect the gear surface and bearing surface for
wear and damage, then measure the mainshaft at
points A, B, and C.
Standard:
A (Ball bearing surface): 27.987 - 28.000 mm
11.1018 - 1.1024 inl
B (Needle bearing surfacel: 37.984 - 38.000 mm(1.4954 - 1.4961 inl
C {Bafl bearing surfacel: 27.977 -27.990 mm
(1.1015 - 1.1020 inl
Service Limit: A:27.94 mm (1.100 in)
B: 37.93 mm (1.'193 inl
C: 27.94 mm 11.100 inl
Inspect oil passages Ior clogging.
lf anv oart of the mainshaft is less than the service
limit. reolace it with a new one.
2. Inspect for runout.
Standard: 0.02 mm (0.0008 in) max.
Service Limit: 0.05 mm 10.002 inl
NOTE: Support the mainshaft at both ends
sh own.
lf the runout is more than the service limit, reDlace
the mainshaft with a new one.

Clearance Inspection
NOTE: lf replacement us required, always replace the
synchro sleeve and hub as a set.
1. Measure the clearance between the lst oear and
thrust washer.
Standard: 0.06 - 0.18 mm (0.@2 - 0.007 in)
Servica Limit:0.23 mm {0.009 in)
THRUST WASHER
2.lf the clearance is more than the service limit, mea-
sure the thickness of the thrust washer.
Standsrd: 1.95 - 1.97 mm (0.077 - 0.078 in)
3. lf the thickness is less than the standard, reDlace the
thrust washer with a new one. lf the thickness is
within the service limit, measure the thickness of
the 1st gear.
Standard: 26.95 - 27.00 mm (1.061 - 1.063 inl
lf the thickness of 1st gear is less than the stan-
dard, replace 1st gear with a new one.
lf the thickness of lst gear is within the standard.
replace 1sv2nd synchro hub with a new one.

Reassembly
Note these items during reassembly:
. Press the 3rd, 4th, and sth gear on the countershaft
without lubrication.
. When installing the 3rd, 4th. and sth gears, suppon
the shaft on steel blocks and install the gears using a
press.
. Refer to page 13-28 for reassembly sequence.
1. Install the thrust shim, needle bearing, 1st gear, and
friction damper.
NOTE: Reassembly the friction damper on the lst
gear before installation.
