Composition Plates
Dry the plates and inspect each, for the following conditions:
| • | Chips or metal particles embedded in the lining |
Replace the set, if any composition plate shows any of the above conditions.
Steel Plates
Important: If the clutch shows evidence of extreme heat or burning, replace the release springs. These may be heat affected as well, and have lost their temper.
Wipe the plates dry and check the plates for heat discoloration. If the surfaces are smooth, even if colour smear is indicated, you can reuse the plate. If the plate is discoloured with heat spots or if the surface is scuffed, replace the plate.
Causes of Burned Clutch Plates
The following conditions can result in a burned clutch plate:
| • | Incorrect usage of clutch plates. |
| • | Valve body conditions, such as: |
| - | The valve body face is not flat. |

| - | The valve bushing clips are improperly installed. |
| - | The checkballs are misplaced. |
| • | The Teflon® seal rings are worn or damaged. |
| • | Engine coolant in the transmission fluid. |
