PROCEDURE
INSPECT COUNTERSHAFT 5TH GEAR
Using a cylinder gauge, measure the inside diameter of the countershaft 5th gear.

| Maximum inside diameter |
|---|
| 38.040 mm (1.4976 in.) |
If the inside diameter is more than the maximum, replace the countershaft 5th gear.
INSPECT COUNTERSHAFT 5TH GEAR THRUST CLEARANCE
Using a feeler gauge, measure the thrust clearance.
| Standard clearance |
|---|
| 0.10 to 0.35 mm (0.00394 to 0.0137 in.) |
If the clearance is not as specified, replace the countershaft 5th gear.
INSPECT COUNTERSHAFT 5TH GEAR RADIAL CLEARANCE
Using a dial indicator, measure the radial clearance.
| Standard clearance |
|---|
| 0.015 to 0.068 mm (0.000591 to 0.00267 in.) |
If the clearance is not as specified, replace the counter 5th gear bearing.
INSPECT NO. 2 SYNCHRONIZER RING
Apply gear oil to the cone of the input shaft, and check that it does not turn in either direction while pushing the No. 2 synchronizer ring.
If it can turn, replace the No. 2 synchronizer ring.
Push the No. 2 synchronizer ring against the cone of the input shaft. Measure the clearance between the No. 2 synchronizer ring and input shaft.
| Standard clearance |
|---|
| 0.70 to 1.70 mm (0.0276 to 0.0669 in.) |
If the clearance is not as specified, replace the No. 2 synchronizer ring.
INSPECT NO. 3 SYNCHRONIZER RING
Apply gear oil to the cone part of the No. 5 gear spline piece, and check that it does not turn in either direction while pushing the No. 3 synchronizer ring against the No. 5 gear spline piece.
If it can turn, replace the No. 3 synchronizer ring.
Push the No. 3 synchronizer ring against the cone part of the No. 5 gear spline piece. Measure the clearance between the No. 3 synchronizer ring and No. 5 gear spline piece.
| Standard clearance |
|---|
| 0.68 to 1.32 mm (0.0268 to 0.0519 in.) |
If the clearance is not as specified, replace the No. 3 synchronizer ring.
INSPECT NO. 1 GEAR SHIFT FORK
Using a vernier caliper, measure the No. 1 gear shift fork groove A and the thickness B.
| Standard groove (A) |
|---|
| 5.20 to 5.36 mm (0.205 to 0.211 in.) |
| Maximum groove (A) |
|---|
| 5.36 mm (0.211 in.) |
| Standard thickness (B) |
|---|
| 4.35 to 4.65 mm (0.172 to 0.183 in.) |
| Minimum thickness (B) |
|---|
| 4.35 mm (0.172 in.) |
If the width is not as specified, replace the No. 1 gear shift fork.
INSPECT NO. 2 GEAR SHIFT FORK
Using a vernier caliper, measure the thickness of the claw part of the No. 2 gear shift fork.
| Standard thickness |
|---|
| 9.9 to 10.0 mm (0.390 to 0.393 in.) |
| Minimum thickness |
|---|
| 9.9 mm (0.390 in.) |
If the width is not as specified, replace the No. 2 gear shift fork.
INSPECT NO. 3 GEAR SHIFT FORK
| *a | Pad |
Using a vernier caliper, measure the thickness of the claw part of the No. 3 gear shift fork.
| Standard thickness |
|---|
| 9.76 to 10.24 mm (0.385 to 0.403 in.) |
| Minimum thickness |
|---|
| 9.76 mm (0.385 in.) |
Note
Check the thickness including the pad.
If the measurement result is less than the minimum or the pad is damaged, replace the No. 3 gear shift fork.
INSPECT NO. 3 TRANSMISSION HUB SLEEVE
Check the sliding condition between the countershaft 5th gear and No. 3 transmission hub sleeve.
Check the spline gear of the No. 3 transmission hub sleeve for wear.
If there are any defects, replace the No. 3 transmission hub sleeve.
Using a vernier caliper, measure the No. 3 transmission hub sleeve groove.
| Standard groove |
|---|
| 10.5 to 10.6 mm (0.414 to 0.417 in.) |
| Maximum groove |
|---|
| 10.6 mm (0.417 in.) |
If the width is not as specified, replace the No. 3 transmission hub sleeve.
INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY
Using a caliper gauge, measure the inside diameter of the reverse idler gear sub-assembly.
| Standard inside diameter |
|---|
| 24.040 to 24.061 mm (0.9465 to 0.9472 in.) |
| Maximum inside diameter |
|---|
| 24.061 mm (0.9472 in.) |
If the inside diameter is more than the maximum, replace the reverse idler gear sub-assembly.
Using a micrometer, measure the diameter of the sliding part of the reverse idler gear sub-assembly on the reverse idler gear shaft.
| Standard diameter |
|---|
| 23.979 to 24.000 mm (0.9441 to 0.9448 in.) |
| Minimum diameter |
|---|
| 23.979 mm (0.9441 in.) |
If the diameter is less than the minimum, replace the reverse idler gear shaft.
Using a feeler gauge, measure the thrust clearance of the shoe part between the reverse idler gear sub-assembly and reverse shift arm.
| Standard clearance |
|---|
| 0.05 to 0.35 mm (0.00197 to 0.0137 in.) |
If the clearance is not as specified, replace the reverse idler gear sub-assembly and reverse shift arm.
