Inspection

INSPECTION
Contact Surfaces
1. Clean the disassembled parts in suitable solvent and blow dry with compressed air.





2. If following surfaces are found with burrs or scratches, smooth with oil stone.
1 Differential case B
2 Differential case A
3 Side gear
4 Pinion mate gear
5 Pinion mate shaft
6 Friction plate guide

Disc and Plate
1. Clean the discs and plates in suitable solvent and blow dry with compressed air.
2. Inspect discs and plates for wear, nicks and burrs.





3. To test if friction disc or plate is not distorted, place it on a surface plate and rotate it by hand with indicating finger of dial gauge resting against disc or plate surface.
Allowable warpage: 0.08 mm (0.0031 inch)
If it exceeds limits, replace with a new plate to eliminate possibility of clutch slippage or sticking.





4. Measure frictional surfaces and projected portions of friction disc, friction plate, spring plate, and determine each part's differences to see if the specified wear limit has been exceeded. If any part has worn beyond the wear limit, and deformed or fatigued, replace it with a new one that is the same thickness as the projected portion.
Wear limit: 0.1 mm (0.004 inch) or less
A - B = Wear limit mm (in)
- Measuring points
A: Projected portion
B: Frictional surface
