Transmission 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 inch)
If the clearance is out of specification, replace the transmission clutch hub No.3, 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 inch)
If the clearance is out of specification, replace the 5th gear, 5th gear needle roller bearing or input shaft.





3. INSPECT REVERSE IDLER GEAR SUBASSEMBLY
(a) Using a caliper gauge, measure the inside diameter of the reverse idler gear.

Inside Diameter: mm (inch):

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 (inch):

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





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





5. INSPECT TRANSMISSION HUB SLEEVE NO.3
(a) Using vernier calipers, measure the width of the transmission hub sleeve No.3 groove and the thickness of the claw part on the gear shift fork No.3, and calculate the clearance.
Standard clearance: 0.15 to 0.35 mm (0.0059 to 0.0138 inch) {A - B}
If the clearance is out of specification, replace the transmission hub sleeve No.3 and gear shift fork No.3 with new ones.





6. INSPECT 5TH GEAR
(a) Using a caliper gauge, measure the inside diameter of the 5th gear.

Inside Diameter: mm (inch):

If the inside diameter exceeds the maximum, replace the 5th gear.





7. INSPECT SYNCHRONIZER RING MIDDLE NO.5
(a) Check that the synchronizer ring middle No.5 rotates smoothly.





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





8. 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 inch)
If the clearance is out of specification, replace the 5th gear, 5th gear needle roller bearing or input shaft.





9. 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 0.0260 inch)
If the clearance is out of specification, replace the transmission clutch hub No.3, 5th gear or input shaft rear radial ball bearing.
