1. Install the piston (6) in the K1 outer disc carrier (1). Check the sealing rings (4 and 5) and replace if necessary. The rounded off edges of the sealing rings must point outwards.
2. Insert the disc spring (7). Insert the disc spring with the curvature towards the piston.
3. Insert the spring plate (8). Insert the spring plate with the curvature towards the sun gear. Check the sealing ring (9), replace if necessary.
4. Place Special Tool 8900 on spring plate (8) and compress the spring until the groove of the snap-ring is exposed.

7. Insert the snap-ring (11).
8. Measure the K1 clutch pack clearance.
a. Mount Special Tool 8901 (1) on the K1 outer disc carrier (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 (3).
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 2.7-3.1 mm (0.1060.122 inch) for three friction disc versions, 3.0-3.4 mm (0.118-0.134 inch) for four disc versions, 3.3-3.7 mm (0.130-0.146 inch) for five disc versions, and 3.6-4.0 mm (0.142-0.158 inch) for six disc versions.
f. Adjust with snap-ring (6), if necessary. Snap-rings are available in thicknesses of 2.6 mm (0.102 inch), 2.9 mm (0.114 inch), 3.2 mm (0.126 inch), 3.5 mm (0.138 inch), 3.8 mm (0.150 inch), and 4.1 mm (0.162 inch).
