Input Shaft
E351 MANUAL TRANSAXLE: INPUT SHAFT: INSPECTION
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.)
If the runout is greater than the maximum, replace the input shaft.
(b) Using a micrometer, measure the diameter of the input shaft journal surface.
Standard diameter:
Minimum diameter:
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.)
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.)
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.)
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.)
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.)
If the clearance is out of the specification, replace the No. 2 transaxle hub sleeve and No. 2 gear shift fork with new ones.
