C50 MANUAL TRANSAXLE: MANUAL TRANSAXLE UNIT: INSPECTION

1. INSPECT NO. 3 SYNCHRONIZER RING





(a) Check the synchronizer ring for wear and damage.

(b) Coat the 5th gear cone with gear oil.

(c) Turn the synchronizer ring in one direction while pushing it against the 5th gear cone.

(d) Check that the ring locks.

If the synchronizer ring does not lock, replace the synchronizer ring.

(e) Using a feeler gauge, measure the clearance between the synchronizer ring back and the gear spline end.





Minimum clearance:

0.75 mm (0.0295 in.)

If the clearance is less than the minimum, replace the synchronizer ring.

2. INSPECT NO. 3 TRANSMISSION HUB SLEEVE





(a) Check the sliding condition between the No. 3 transmission hub sleeve and No. 3 transmission clutch hub.

(b) Check that the edges of the No. 3 transmission hub sleeve spline gear are not worn down.

(c) Using vernier calipers, 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 (0.012 to 0.0020 in.)

If the clearance exceeds the standard, replace the No. 3 transmission hub sleeve and No. 3 gear shift fork.

3. INSPECT 5TH GEAR





(a) 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.

4. INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY





(a) Using a caliper gauge, inspect the reverse idler gear.

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.

(b) 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.
