INSPECTION
NMMT0056
Counter Gear Shaft
NMMT0056S01
I
Check the gears for any damage, wear, or flaking.
I
Support the counter gear shaft with a V-block to check for
runout by measuring at each position shown in the figure. If the
measured value exceeds the limit, replace the shaft.
Limit: Less than 0.03 mm (0.0012 in)
Gears
NMMT0056S02
I
Check each gear for damage, wear, or flaking.
I
Install the 3rd outer baulk ring, synchronizer cone and outer
baulk ring to the 3rd counter gear. Press the outer baulk ring
closely to the 3rd counter gear and check if the clearance is
within the specified range given below.
I
Press the 4th outer baulk ring closely to the 4th counter gear
and check if each clearance is within the specified range given
below.

I
Install the 3rd outer baulk ring, synchronizer cone and outer
baulk ring to the 3rd counter gear. Make sure that, when try-
ing to rotate the outer baulk ring pressed closely to the 3rd
counter gear, the baulk ring does not slip.
I
Make sure that, when trying to rotate the 4th baulk ring pressed
closely to the 4th counter gear, the baulk ring does not slip.

Measure the thickness of the claw of the shift fork and the
width of the coupling sleeve groove to calculate the clearance
to the shift fork. Check the clearance.
Calculation formula:
Width of coupling sleeve groove [mm (in)] – Thickness of claw
of shift fork [mm (in)]
Standard: 0.15 - 0.35 mm (0.0059 - 0.0138 in)

ASSEMBLY
NMMT0057
1.
Install the 3rd & 4th synchronizer hub, insert key and insert
spring to coupling sleeve. Then, install the insert ball.
2.
Set the assembled 3rd & 4th coupling sleeve and the 3rd & 4th
synchronizer hub onto a drift (SST). Aligning the projecting
tabs of the inner baulk ring, synchronizer cone and of the outer
baulk ring with the cutouts of the 3rd counter gear and the 3rd
& 4th synchronizer hub. Install the counter shaft to the 3rd &
4th synchronizer hub with a press.
3.
After installation, make sure the baulk rings move co-axially.
4.
Install the 4th outer baulk ring, 4th counter gear and 4th gear
bushing to the counter gear shaft.
5.
Assemble the thrust washer, retaining ring and snap rings that
were removed during disassembling. Measure the clearance
and select a thrust washer to obtain the specified value.
