Removing and installing the safety ring –  Push the spring piston cover downwards with tool -T20023- until the safety ring can be fitted into the recess.

Fitting the inner and outer discs The convex side of the plate spring (small diameter) should face the clutch bell housing. –  Fit the outer discs -2- and inner discs -4- onto the plate spring -3-. –  Fit the support disc -5- onto the last inner disc. –  Fit the safety ring -1- in the recess of the clutch bell housing.

Determining the thickness of the support disc –  Using a feeler gauge “A”, measure the play between the safety ring and the support disc.

Component	Dim.	Wear limit
Clutch K1	0.45 ... 0.85 mm	1.05 mm

–  If the wear limit is reached with the used clutch, it will be necessary to change the discs and select a new support disc. –  Choose the discs and the support disc according to the gearbox code.

Checking the clutch action –  Before fitting the piston, moisten the sealing lips and oil seals with ATF. –  Turn the piston slightly when fitting,. –  Once the piston is fitted to the clutch or brakes, it should be possible to turn it easily by hand in both directions -arrows-. –  If this is not the case, perhaps the sealing lips or oil seals are incorrectly fitted or damaged. –  Check the lips or oil seals for damage and replace if necessary. –  Refit the piston and check again.

–  Blow compressed air into the pressure channel -arrow-. –  Seal the orifice on the opposite side. –  The clutch piston should compress the disc package. –  Release the air pressure. The discs should return to their resting position.
