Inspecting Clutch Disk
Inspection
| - 1. The clutch linings are riveted to undulated spring segments which
curve from side to side and provide a cushioning effect in the clutch
disc. It is essential for proper functioning of the clutch that the
cushioning action of individual segments is equal in all sections of
the clutch disc.
- 2. The clutch disc should slide freely on the splined input shaft but
it must not show evidence of radial play,
- 3. Inspect clutch linings. If the linings are oiled, scorched, torn,
or worn considerably. install a new clutch disc.
Visible formation of cracks in the lining surface between the rivets
can be disregarded.
Clutch disc with riveted linings:
Compressed thickness = 9,2 +/- 0,2 mm (0.362 +/- 0.008 in)
Wear limit = 8 - 7. 8 mm (0.315 - 0.307 in)
Measurements are taken between both friction surfaces of the clutch disc.
Thickness A, decompressed = 10,1 - 0.4 mm (0.398 - 0.016 in)
|
| - 4. Check clutch disc for run out at linings: Permissible runout is 0.6
mm (0.024 in).
- 5. Check torsion damper for firm seating and inspect spring supporting
plates for cracks. Replace clutch disc if detective,
Note:
Replacement of clutch linings should not be undertaken; if worn,
install a new clutch disc.
