GZD15, WSM TRANSAXLE
2-S26
[2] TRANSMISSION CASE
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 defect, replace it.
Backlash and Tooth Contact between 19T Spiral Gear (A) and
19T Spiral Gear (B)
1. Measure the backlash between the 19T spiral gear (A) (1) and
19T spiral gear (B) (2).
2. When the backlash is too large, decrease the number of shims
at the side of the 19T spiral gear (A) (1), and add the shims at
the opposite side. When the backlash is too small, decrease
the number of shims at the side of the differential case, and
add the shims at the opposite side.
3. Adjust the backlash properly by repeating the above
procedure.
4. Apply red lead lightly over several teeth at three positions
equally spaced on the hypoid ring gear.
5. Turn the 19T spiral gear (B) (2) by input shaft while pressing a
wooden piece against the periphery of the bevel gear.
6. Check the tooth contact, if not proper, adjust according to the
following instruction.
