(1) Bearing, Gear and Shaft
Checking Bearing
1. Hold the inner race, and push and pull the outer race in all
directions to check for wear and roughness.
2. Apply transmission fluid to the bearing, and hold the inner race.
Then turn the outer race to check rotation.
3. If there is any damage, replace it.

Clearance between Gear and Spline
1. Secure the gear with a vise.
2. Set a dial indicator (lever type) with its finger on the spline.
3. Move the shaft to measure the clearance.
4. If the clearance exceeds the allowable limit, replace them.
9Y1211167TRS0144US0
Clearance between Shift Fork and Shift Gear Groove
1. Place for in the groove to check clearance with feeler gauge.
2. If the clearance exceeds allowable limit, replace.
9Y1211167TRS0145US0
Clearance between Gear and Shaft
1. Measure the shaft O.D. (rubbing surface).
2. Measure the gear I.D. (rubbing surface).
3. Measure the O.D. of the two needles installed diagonally in the
needle bearing.
4. Calculate the clearance
(Clearance = Gear I.D. – {(2 × needle O.D.) + shaft O.D.})
5. If the clearance exceeds the allowable limit, replace them.
