Input Shaft

E351 MANUAL TRANSAXLE: INPUT SHAFT: INSPECTION

1. INSPECT INPUT SHAFT





(a) Using V-blocks and dial indicator, measure the shaft for runout.

Maximum runout:

0.03 mm (0.0012 in.)

(b) If the runout is greater than the maximum, replace the input shaft.

(c) Using a micrometer, measure the diameter of the input shaft journal surface.





Standard diameter:





Minimum diameter:





(d) If the diameter is less than the minimum, replace the input shaft.

2. INSPECT 4TH GEAR





(a) Using a cylinder gauge, measure the inside diameter of the 4th gear.

Standard inside diameter:

42.009 to 42.025 mm (1.6539 to 1.6545 in.)

Maximum inside diameter:

42.025 mm (1.6545 in.)

(b) If the inside diameter is greater than the maximum, replace the 4th gear.

3. INSPECT 3RD GEAR





(a) Using a cylinder gauge, measure the inside diameter.

Standard inside diameter:

43.009 to 43.025 mm (1.6933 to 1.6939 in.)

Maximum inside diameter:

43.025 mm (1.6939 in.)

(b) If the inside diameter is greater than the maximum, replace the 3rd gear.

4. INSPECT NO. 4 SYNCHRONIZER OUTER RING





(a) Coat the 4th gear cone with gear oil. Turn the No. 4 synchronizer outer ring in one direction while pushing it against the 4th gear cone. Check that the ring locks.

If the No. 4 synchronizer outer ring does not lock, replace the ring or the 4th gear.

(b) Using a feeler gauge, measure the clearance between the No. 4 synchronizer outer ring back and 4th gear spline end.

Standard clearance:

0.7 to 1.45 mm (0.0276 to 0.0571 in.)

(c) If the clearance is out of the specification, replace the No. 4 synchronizer outer ring.





5. INSPECT NO. 3 SYNCHRONIZER RING





(a) Coat the 3rd gear cone with gear oil. Turn the No. 3 synchronizer ring in one direction while pushing it against the 3rd gear cone. Check that the ring locks.

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

(b) Using a feeler gauge, measure the clearance between the No. 3 synchronizer ring back and 3rd gear spline end.





Standard clearance:

0.65 to 1.75 mm (0.0256 to 0.0689 in.)

(c) If the clearance is out of the specification, replace the No. 3 synchronizer ring.

6. INSPECT NO. 2 TRANSAXLE HUB SLEEVE





(a) Inspect the sliding condition between the No. 2 transaxle hub sleeve and No. 2 transaxle clutch hub.

(b) Inspect the tip of the spline gear on the No. 2 transaxle hub sleeve for wear.

If any defects are found, replace the transaxle hub sleeve or the transaxle clutch hub.

(c) Using vernier calipers, measure the width of the No. 2 transaxle hub sleeve groove (A) and the thickness of the claw part on the No. 2 gear shift fork (B), and calculate the clearance.





Standard clearance:

A - B = 0.11 to 0.69 mm (0.0043 to 0.0272 in.)

(d) If the clearance is out of the specification, replace the No. 2 transaxle hub sleeve and No. 2 gear shift fork with new ones.
