PROCEDURE
INSPECT OUTPUT SHAFT
Using a dial indicator, measure the output shaft runout.
| Maximum runout |
|---|
| 0.03 mm (0.00118 in.) |
If the runout is more than the maximum, replace the output shaft with a new one.
Using a micrometer, measure the journal diameter at A, B and C on the output shaft.
| Standard Journal Diameter | ||||||||
|---|---|---|---|---|---|---|---|---|
|
If the diameter is not as specified, replace the output shaft with a new one.
Using a micrometer, measure the thickness of the output shaft flange as shown in the illustration.
| Standard thickness |
|---|
| 4.8 to 5.2 mm (0.189 to 0.204 in.) |
If the thickness is not as specified, replace the output shaft.
INSPECT 3RD GEAR
Using a cylinder gauge, measure the inside diameter of the 3rd gear.
| Standard inside diameter |
|---|
| 44.015 to 44.040 mm (1.7329 to 1.7339 in.) |
| Maximum inside diameter |
|---|
| 44.040 mm (1.7339 in.) |
If the inside diameter is more than the maximum, replace the 3rd gear with a new one.
INSPECT 2ND GEAR
Using a cylinder gauge, measure the inside diameter of the 2nd gear.
| Standard inside diameter |
|---|
| 53.015 to 53.040 mm (2.0872 to 2.0881 in.) |
| Maximum inside diameter |
|---|
| 53.040 mm (2.0881 in.) |
If the inside diameter is more than the maximum, replace the 2nd gear with a new one.
INSPECT 1ST GEAR
Using a cylinder gauge, measure the inside diameter of the 1st gear.
| Standard inside diameter |
|---|
| 46.015 to 46.040 mm (1.812 to 1.8126 in.) |
| Maximum inside diameter |
|---|
| 46.040 mm (1.8126 in.) |
If the inside diameter is more than the maximum, replace the 1st gear with a new one.
INSPECT 1ST GEAR THRUST WASHER
Using a micrometer, measure the thickness of the thrust washer.
| Standard thickness |
|---|
| 5.95 to 6.05 mm (0.235 to 0.238 in.) |
| Minimum thickness |
|---|
| 5.95 mm (0.235 in.) |
If the thickness is less than the minimum, replace the 1st gear thrust washer.
INSPECT NO. 1 SYNCHRONIZER RING SET (for 1st Gear)
Apply gear oil to the cone of the 1st gear, and check that the No. 1 synchronizer ring set does not turn in either direction while pushing the No. 1 synchronizer ring set.
If No. 1 synchronizer ring set turns, replace it.
Measure the clearance between the No. 1 synchronizer ring and 1st gear while pushing the No. 1 synchronizer ring against the cone of the 1st gear.
| Standard clearance |
|---|
| 0.75 to 1.65 mm (0.0295 to 0.0650 in.) |
If the clearance is not as specified, replace the No. 1 synchronizer ring with a new one.
INSPECT NO. 1 SYNCHRONIZER RING SET (for 2nd Gear)
Apply gear oil to the cone of the 2nd gear, and check that No. 1 synchronizer ring set does not turn in either direction while pushing the No. 1 synchronizer ring set.
If No. 1 synchronizer ring set turns, replace it.
Push the No. 1 synchronizer ring set against the cone of the 2nd gear. Measure the clearance between the No. 1 synchronizer ring set and 2nd gear.
| Standard clearance |
|---|
| 0.65 to 1.75 mm (0.0256 to 0.0689 in.) |
If the clearance is not as specified, replace the No. 1 synchronizer ring with a new one.
INSPECT NO. 2 SYNCHRONIZER RING (for 3rd Gear)
Apply gear oil to the cone of the 3rd gear, and check that No. 2 synchronizer ring does not turn in either direction while pushing the No. 2 synchronizer ring.
If the No. 2 synchronizer ring turns, replace it.
Push the No. 2 synchronizer ring against the cone of the 3rd gear. Measure the clearance between the No. 2 synchronizer ring (for the 3rd gear) and 3rd gear.
| Standard clearance |
|---|
| 0.75 to 1.65 mm (0.0295 to 0.0650 in.) |
If the clearance is not as specified, replace the No. 2 synchronizer ring with a new one.
INSPECT REVERSE GEAR
Using a vernier caliper, measure the groove of the No. 1 shift fork and the thickness of flange of the reverse gear. Then calculate the clearance between the No. 1 shift fork and flange.
| Standard clearance |
|---|
| 0.15 to 0.41 mm (0.00591 to 0.0161 in.) |
If the clearance is not as specified, replace the reverse gear and No. 1 shift fork with new ones.
INSPECT NO. 1 TRANSMISSION CLUTCH HUB
Check the sliding condition between the No. 1 clutch hub and reverse gear.
Check the spline of the reverse gear for wear.
If there are any defects, replace the No. 1 clutch hub.
INSPECT NO. 2 TRANSMISSION HUB SLEEVE
Using a vernier caliper, measure the groove of the No. 2 hub sleeve and the thickness of claw of the No. 2 shift fork. Then calculate the clearance between the No. 2 hub sleeve and the claw.
| Standard clearance |
|---|
| 0.15 to 0.35 mm (0.00591 to 0.0138 in.) |
If the clearance is not as specified, replace the No. 2 hub sleeve and No. 2 shift fork with new ones.
INSPECT TRANSMISSION CLUTCH HUB NO. 2
Check the sliding condition between the No. 2 clutch hub and No. 2 hub sleeve.
Check the splines of the No. 1 clutch hub for wear.
Check the tip of the spline gear sleeve of the reverse gear for wear.
If there are any defects, replace the No. 1 clutch hub or reverse gear.
