COUNTER GEAR AND REVERSE IDLER
GEAR COMPONENT PARTS
INSPECTION
1. INSPECT COUNTER 5 TH GEAR RADIAL CLEARANCE
(a) Install the spacer, counter 5th gear and needle roller bearing
to the counter gear.
(b) Using a dial indicator, measure the counter 5th gear radial
clearance.
Standard clearance:
0.009±0.060 mm (0.0004±0.0024 in.)
Maximum clearance:
0.150 mm (0.0059 in.)
If the clearance exceeds the maximum, replace the counter
gear or needle roller bearing or counter 5th gear.

2. INSPECT COUNTER GEAR
Using a micrometer, measure the outer diameter of the
counter shaft journal.
Minimum diameter:
Part A
26.975 mm (1.0620 in.)
Part B
29.950 mm (1.1791 in.)
3. INSPECT REVERSE IDLER GEAR RADIAL CLEARANCE
Using a dial indicator, measure the reverse idler gear radial
clearance.
Standard clearance:
0.041±0.074 mm (0.0016±0.0029 in.)
Maximum clearance:
0.194 mm (0.0076 in.)
If the clearance exceeds the maximum, replace the gear or
shaft.
4. INSPECT CLEARANCE OF REVERSE IDLER GEAR AND
SHIFT ARM SHOE
Using a feeler gauge, measure the clearance between the re-
verse idler gear and shift arm shoe.
Standard clearance:
0.20±0.41 mm (0.008±0.0161 in.)
Maximum clearance:
0.9 mm (0.0354 in.)
If the clearance exceeds the maximum, replace the shift arm
shoe or reverse idler gear.
5. INSPECT 5TH GEAR SYNCHRONIZER RING
(a) Check for wear or damage.
(b) Install the synchronizer pull ring, cone ring and outer ring to
the 5th gear.
(c) Check the braking effect of the synchronizer ring.
Turn the synchronizer ring in one direction while pushing it to
the gear cone. Check that the ring locks.
If it does not lock, replace the synchronizer ring. MT1±36

6. INSPECT CLEARANCE OF SHIFT FORKS AND HUB
SLEEVES
Using a feeler gauge, measure the clearance between the
hub sleeve and shift fork.
Maximum clearance:
1.0 mm (0.039 in.)
If the clearance exceeds the maximum, replace the shift fork
or hub sleeve.
BEARING REPLACEMENT
1. IF NECESSARY, REPLACE COUNTER GEAR FRONT
BEARING AND SIDE RACE
(a) Using a snap ring expander, remove the snap ring.
(b) Using SST and a press, press out the bearing.
SST 09950±00020
(c) Check the side race for wear or damage.
(d) If necessary, remove the side race.
wUsing SST and a socket wrench, remove the side race.
SST 09950±40010
(e) Using a socket wrench, press in a new bearing, side race and
inner race.
(f) Select a snap ring that will allow minimum axial play.
