Clutch assemblies - assembling

8. Check clutch end plates for signs of overheating and wear, plates which are discoloured or worn must be replaced.

CAUTION: Clutch end plates are selective thickness. Thickness of end plate required can only be established when clutch is assembled. In order to provide initial datum for measuring end plate to disc clearance, note the number marked on the face of the original end plate and ensure that if a replacement plate is to be fitted, it carries the same number as the original. On the 1st hold clutch, plates are numbered 1 to 4 and 6 to 7 with one plate having no number.
