6. INSPECT 1ST GEAR BEARING INNER RACE
(a) Using a micrometer, measure the outside diameter of the 1st gear bearing inner race.
Standard outer diameter:
40.284 to 40.300 mm (1.58598 to 1.58661 in.)
Minimum outer diameter:
40.284 mm (1.58598 in.)
HINT
If the outside diameter is less than the minimum, replace the 1st gear bearing inner race with a new one.
7. INSPECT NO. 1 TRANSMISSION HUB SLEEVE CLEARANCE
(a) Using a vernier caliper, measure the claw width of the No. 1 gear shift fork.
Standard width:
7.9 to 8.0 mm (0.311 to 0.315 in.)
Minimum width:
7.9 mm (0.311 in.)
HINT
If the width is less than the minimum, replace the No. 1 gear shift fork with a new one.
(b) Using a vernier caliper, measure the groove of the No. 1 transmission hub sleeve, and then calculate the clearance with the No. 1 gear shift fork.
Standard clearance:
0.15 to 0.35 mm (0.00590 to 0.0138 in.)
Maximum clearance:
0.35 mm (0.0138 in.)
HINT
If the clearance exceeds the maximum, replace both the No. 1 gear shift fork and No. 1 transmission hub sleeve with a new ones.
8. INSPECT NO. 3 TRANSMISSION HUB SLEEVE CLEARANCE
(a) Using a vernier caliper, measure the claw width of the No. 3 gear shift fork.
Standard width:
7.9 to 8.0 mm (0.311 to 0.315 in.)
Minimum width:
7.9 mm (0.311 in.)
HINT
If the width is less than the minimum, replace the No. 3 gear shift fork with a new one.
(b) Using a vernier caliper, measure the groove of the No. 3 transmission hub sleeve, and then calculate the clearance with the No. 3 gear shift fork.
Standard clearance:
0.15 to 0.35 mm (0.00590 to 0.0138 in.)
Maximum clearance:
0.35 mm (0.0138 in.)
HINT
If the clearance exceeds the maximum, replace both the No. 3 gear shift fork and No. 3 transmission hub sleeve with a new ones.
9. INSPECT NO. 1 TRANSMISSION HUB SLEEVE
(a) Check that the spline gear edges of the No. 1 transmission hub sleeve are not worn down.
HINT
If it shows any sign of wear, replace the No. 1 transmission hub sleeve with a new one.
(b) Install the No. 1 transmission hub sleeve to the No. 1 transmission clutch hub, and then check that it slides smoothly.
HINT
If it does not slide smoothly, replace the No. 1 transmission hub sleeve and No. 1 transmission clutch hub with a new one.
10. INSPECT NO. 3 TRANSMISSION HUB SLEEVE
(a) Check that the spline gear edges of the No. 3 transmission hub sleeve are not worn down.
HINT
If it shows any sign of wear, replace the No. 3 transmission hub sleeve with a new one.
(b) Install the No. 3 transmission hub sleeve to the No. 3 transmission clutch hub, and then check that it slides smoothly.
HINT
If it does not slide smoothly, replace the No. 3 transmission hub sleeve and No. 3 transmission clutch hub with a new one.
11. INSPECT NO. 1 SYNCHRONIZER RING SET (for 1st Gear)
(a) Apply manual transmission gear oil to the taper cone of the 1st gear and No. 1 synchronizer ring set, and then hold the No. 1 synchronizer ring set in position with your hand to measure the clearance between the No. 1 synchronizer ring set and the 1st gear by using a feeler gauge.
Standard Clearance:
NOTICE:
Check the entire circumference of the gear.
HINT
If the result is not as specified, replace the No. 1 synchronizer ring set and 1st gear with a new one.
(b) Apply manual transmission gear oil to the taper cone of the 1st gear, and then hold the No. 1 synchronizer ring set in position with your hand to check that it does not slide in the circumferential direction.
HINT
If the No. 1 synchronizer ring set slides, replace the No. 1 synchronizer ring set and 1st gear with a new one.
12. INSPECT NO. 1 SYNCHRONIZER RING SET (for 2nd Gear)
(a) Apply manual transmission gear oil to the taper cone of the 2nd gear and No. 1 synchronizer ring set, and then hold the No. 1 synchronizer ring set in position with your hand to measure the clearance between the No. 1 synchronizer ring set and the 2nd gear by using a feeler gauge.
Standard Clearance:
NOTICE:
Check the entire circumference of the gear.
HINT
If the result is not as specified, replace the No. 1 synchronizer ring set and 2nd gear with a new one.
(b) Apply manual transmission gear oil to the taper cone of the 2nd gear, and then hold the No. 1 synchronizer ring in position with your hand to check that it does not slide in the circumferential direction.
HINT
If the No. 1 synchronizer ring set slides, replace the No. 1 synchronizer ring set and 2nd gear with a new one.
