E351 MANUAL TRANSAXLE: MANUAL TRANSAXLE UNIT: INSPECTION

INSPECTION

1. INSPECT 5TH GEAR THRUST CLEARANCE





(a) Using a dial indicator, inspect the 5th gear thrust clearance.
Standard clearance:
0.10 to 0.65 mm (0.0039 to 0.0256 in.)
If clearance is not as specified, replace the No. 3 transmission clutch hub, 5th gear, or input shaft rear radial ball bearing.
2. INSPECT 5TH GEAR RADIAL CLEARANCE





(a) Using a dial indicator, inspect the 5th gear radial clearance.
Standard clearance:
0.009 to 0.050 mm (0.0004 to 0.0020 in.)
If clearance is not as specified, replace the 5th gear, 5th gear needle roller bearing, or input shaft.
3. INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY





(a) Using a caliper gauge, measure the inside diameter of the reverse idler gear.
Inside diameter: mm (in.):





If the inside diameter exceeds the maximum, replace the reverse idler gear.





(b) Using a micrometer, measure the outside diameter of the reverse idler gear shaft.
Outside diameter: mm (in.):





If the outside diameter is less than the minimum, replace the reverse idler gear shaft.
4. INSPECT NO. 3 TRANSMISSION CLUTCH HUB





(a) Inspect the sliding condition between the No. 3 transmission clutch hub and the No. 3 transmission hub sleeve.
(b) Inspect the tip of the spline gear on the No. 3 transmission hub sleeve for wear.
5. INSPECT NO. 3 TRANSMISSION HUB SLEEVE





(a) Using vernier calipers, measure the width of the No. 3 transmission hub sleeve groove and the thickness of the claw on the No. 3 gear shift fork, and calculate the clearance.
Standard clearance:
0.15 to 0.35 mm (0.0059 to 0.0138 in.) {A - B}
If clearance is not as specified, replace the No. 3 transmission hub sleeve and No. 3 gear shift fork with new ones.
6. INSPECT 5TH GEAR





(a) Using a caliper gauge, measure the inside diameter of the 5th gear.
Inside diameter mm (in.):





If the inside diameter exceeds the maximum, replace the 5th gear.
7. INSPECT NO. 5 SYNCHRONIZER RING MIDDLE





(a) Check that the No. 5 synchronizer ring middle rotates smoothly.





(b) Check that the No. 5 synchronizer ring middle does not rotate while pushing it against the No. 3 clutch hub.
