C50 MANUAL TRANSMISSION / TRANSAXLE MANUAL TRANSAXLE UNIT INSPECTION
PROCEDURE
33369
1.INSPECT NO. 3 SYNCHRONIZER RING
| *a | Locks |
Check for wear and damage.
Coat the 5th gear cone with gear oil.
Turn the No. 3 synchronizer ring in one direction while pushing it against the 5th gear cone.
Check that the No. 3 synchronizer ring locks.
If the No. 3 synchronizer ring does not lock, replace it.
Using a feeler gauge, measure the clearance between the No. 3 synchronizer ring and the gear spline end.
- Standard Clearance:
0.75 to 1.65 mm (0.0295 to 0.0650 in.)
- Minimum Clearance:
0.75 mm (0.0295 in.)
If the clearance is less than the minimum, replace the No. 3 synchronizer ring.
33395
2.INSPECT NO. 3 TRANSMISSION HUB SLEEVE
Check the sliding condition between the No. 3 transmission hub sleeve and No. 3 transmission clutch hub.
Check that the edges of the No. 3 transmission hub sleeve spline gear are not worn down.
Using a vernier caliper, measure the width of the No. 3 transmission hub sleeve groove (A) and the thickness of the claw part on the No. 3 gear shift fork (B), and calculate the clearance.
- Standard Clearance (A) - (B):
0.3 to 0.5 mm (0.0118 to 0.0197 in.)
If the clearance is not as specified, replace the No. 3 transmission hub sleeve and No. 3 gear shift fork.
33336
3.INSPECT 5TH GEAR
Using a caliper gauge, measure the inside diameter of the 5th gear.
- Standard Inside Diameter:
29.915 to 29.931 mm (1.1778 to 1.1783 in.)
- Maximum Inside Diameter:
29.931 mm (1.1783 in.)
If the inside diameter exceeds the maximum, replace the 5th gear.
33402
4.INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY
Using a caliper gauge, inspect the reverse idler gear sub-assembly.
- Standard Inside Diameter:
18.040 to 18.058 mm (0.7102 to 0.7109 in.)
- Maximum Inside Diameter:
18.058 mm (0.7109 in.)
If the inside diameter exceeds the maximum, replace the reverse idler gear sub-assembly.
Using a micrometer, inspect the reverse idler gear shaft.
- Standard Outer Diameter:
17.966 to 17.984 mm (0.7073 to 0.7080 in.)
- Minimum Outer Diameter:
17.966 mm (0.7073 in.)
If the outer diameter is less than the minimum, replace the reverse idler gear shaft.
