Manual Transaxle Unit (for Hatchback)

C50 MANUAL TRANSMISSION / TRANSAXLE: MANUAL TRANSAXLE UNIT (for Hatchback): INSPECTION

1. INSPECT NO. 3 SYNCHRONIZER RING





(a) Check for wear and damage.

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

(c) Turn the No. 3 synchronizer ring in one direction while pushing it against the 5th gear cone.

(d) Check that the ring locks.

If the No. 3 synchronizer ring does not lock, replace the No. 3 synchronizer ring.

(e) Using a feeler gauge, measure the clearance between the No. 3 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 No. 3 synchronizer ring.

2. INSPECT NO. 3 TRANSMISSION HUB SLEEVE





(a) Check the sliding condition between 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 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.





Text in Illustration





Standard clearance (A - B):

0.3 to 0.5 mm (0.0118 to 0.00197 in.)

If the clearance exceeds the standard, replace 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 1.1784 in.)

Maximum inside diameter:

29.931 mm (1.1784 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 idle gear sub-assembly.

Standard inside diameter:

18.040 to 18.058 mm (0.710 to 0.711 in.)

Maximum inside diameter:

18.058 mm (0.711 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 as shown in the illustration.

Standard outer diameter:

17.966 to 17.984 mm (0.707 to 0.708 in.)

Minimum outer diameter:

17.966 mm (0.707 in.)

If the outer diameter is less than the minimum, replace the reverse idler gear shaft.
