Input Shaft
E350 MANUAL TRANSAXLE: INPUT SHAFT: INSPECTION
INSPECTION
1. INSPECT INPUT SHAFT
(a) Using a V-block 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 outside diameter of the input shaft journal surface.
Standard outside diameter:
Minimum outside diameter:
If the outside 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 2ND SYNCHRONIZER OUTER RING
(a) Coat the 4th gear cone with gear oil. Turn the 2nd synchronizer outer ring (synchronizer ring No. 4) in one direction while pushing it against the 4th gear cone. Check that the ring locks.
If the 2nd synchronizer outer ring does not lock, replace the ring or the 4th gear.
(b) Using a feeler gauge, measure the clearance between the 2nd synchronizer outer ring (No. 4 synchronizer ring) back and 4th gear spline end.
Standard clearance:
0.75 to 1.65 mm (0.0295 to 0.0650 in.)
If the clearance is out of specification, replace the 2nd 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 specification, replace the No. 3 synchronizer ring.
6. INSPECT NO. 2 TRANSMISSION HUB SLEEVE
(a) Inspect the sliding condition between the No. 2 transmission hub sleeve and No. 2 transmission clutch hub.
(b) Inspect the tip of the spline gear on the No. 2 transmission hub sleeve for wear.
If any defects are found, replace the transmission hub sleeve or the transmission clutch hub.
(c) Using vernier calipers, measure the width of the No. 2 transmission 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
If the clearance is out of specification, replace the No. 2 transmission hub sleeve and No. 2 gear shift fork with new ones.
