Driving Clutch K2
DRIVING CLUTCH K2ASSEMBLY
1. Install the piston (6) in the outer multiple-disc carrier. Inspect the seals (4 and 5), replace if necessary. The rounded edges of the seals must point to the outside.
2. Insert the disc spring (7) and the spring retainer (9). Insert the disc spring (7) with the curved side pointing toward the spring retainer (9). Inspect the seal (8), replace if necessary.
3. Place Special Tool 8900 on the spring plate (1) and press until the groove of the snap-ring is exposed.
4. Insert the snap-ring (2).
5. Insert the disc spring.
Note: Pay attention to the sequence of the discs. Place new friction multiple-discs in ATF fluid for one hour before installing.
6. Insert the multiple-disk set into the outer multiple-disk carrier.
7. Fit the snap-ring.
8. Measure the K2 clutch clearance.
a. Mount Special Tool 8901 (1) on the outer multiple disc (2).
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 (6) and outer multiple-disc (4).
d. During the measurement the snap-ring (6) 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, 2.5-2.9 mm (0.099-0.114 inch) for five disc versions, and 2.7-3.1 mm (0.106-0.122 inch) for six disc versions.
f. Adjust with snap-ring (6), if necessary. Snap-rings are available in thicknesses of 2.3 mm (0.091 inch), 2.6 mm (0.102 inch), 2.9 mm (0.114 inch), 3.2 mm (0.126 inch), 3.5 mm (0.138 inch), and 3.8 mm (0.150 inch).
9. Insert the thrust bearing (2) into the K1 inner disc carrier. Insert the thrust bearing (2) with a little grease to prevent it from slipping.
10. Install the input shaft and k2 clutch in the K1 inner disc carrier with integrated front gear set (1).
11. Fit the hollow gear (14). Pay attention to the installation position.
