Transmission Inspection

17. Replace seals on the cam and shafts.

1. Inspect transmission case for cracks, worn or

damaged bearing bores, damaged threads, or any

other damage that could affect operation of the

transmission.

2. Inspect the front face of the case for small nicks

or burrs that could cause misalignment of the

transmission with the flywheel housing. Remove

all small nicks or burrs with a fine file.

3. Replace any cover that is bent or distorted. Make

sure that the vent hole in the cover is open.

4. Check the condition of the shift levers, forks, shift

rails, and the lever and shafts.

5. Inspect the bearings. Refer to Bearing Inspection.
6. Replace roller bearings that are broken, worn or

rough, and check their respective races.

Taper Roller Bearings Inspection

NOTE: It is recommended to replace all bearings

during a major overhaul of the gearbox. The cost of

removing and disassembling transmissions is too high

to run the risk of bearing damage after they have

been put back together.

1. If it is desired to reuse bearings, the cone

assembly must not be removed from the

component. The bearings should be inspected for

the following damage:

Discolouration of surfaces by heat.
Excessive pitting and bruising caused by

foreign material.
Etching or corrosion.
Spalls from fatigue of metal.
Scoring of roller ends due to inadequate

lubrication.
Damaged bearing cage.
Gauges or nicks on bearing surfaces.

NOTE: The bearing should be replaced as a unit. Do

not replace cup or cone assembly only.

Fluid Level Check

1. Clean around the filler plug and remove the plug.
2. If lubricant does not flow from the filler hole, fill the

case with the specified lubricant until it is level

with the bottom of the filler hole with vehicle in a

level position.
