Driving Clutch K3
DRIVING CLUTCH K3ASSEMBLY
1. Install the piston (6) in the outer disc carrier (8). Check the sealing ring (7) and replace if necessary. The rounded off edges of the sealing ring must point outwards.
2. Insert the spring plate (5). Insert the spring plate (5) with the curvature towards the piston.
3. Mount Special Tool 8900 (9) on the spring plate (5) and clamp until the snap-ring groove is exposed.
4. Insert the snap-ring (4). The collar of the snap-ring (4) must point towards the disc pack (2).
Note: Pay attention to the sequence of the discs. Place new friction multiple-discs in ATF fluid for one hour before installing.
5. Install the disc spring (3) and the multiple disc pack (2) in the outer disc carrier (8).
6. Insert the snap-ring (1).
7. Measure the K3 clutch clearance.
a. Mount Special Tool 8901 (1) on the outer disc carrier.
b. Using a lever press, compress the pressing tool as far as the stop (then the marking ring is still visible, see small arrow).
c. Using a feeler gauge, determine the play "L" at three points between the snap-ring (8) and outer multiple-disc (2).
d. During the measurement, the snap-ring must contact the upper bearing surface of the groove in the outer multiple-disc carrier.
e. The correct clutch clearance is 2.3-2.7 mm (0.0910.106 inch) for three friction disc versions, 2.4-2.8 mm (0.095-0.110 inch) for four disc versions, and 2.5-2.9 mm (0.099-0.114 inch) for five disc versions.
f. Adjust with snap-ring, if necessary. Snap-rings are available in thicknesses of 2.0 mm (0.079 inch), 2.3 mm (0.091 inch), 2.6 mm (0.102 inch), 2.9 mm (0.114 inch), 3.2 mm (0.126 inch), and 3.5 mm (0.138 inch).
