K3
NAG1 TRANSMISSIONDRIVING CLUTCH K3
DISASSEMBLY
1. Remove snap-ring (1) (Fig. 85) from outer multiple-disc carrier.
2. Remove multiple-disc pack (2) and disk spring (3) from outer multiple-disc carrier.
3. Place Multi-use Spring Compressor 8900 (9) (Fig. 85) on disc spring (5) and compress the spring until the snap-ring (4) is exposed.
4. Remove snap-ring (4).
5. Remove spring plate (5) and piston (6) from outer multiple-disc carrier.
ASSEMBLY
1. Install piston (6) in the outer multiple-disc carrier (8). Check sealing ring (7), replace if necessary. The rounded off edges of the sealing ring must point outwards.
2. Insert disc spring (5). Insert disc spring with the curvature towards the piston.
3. Mount the Multi-use Spring Compressor 8900 (9) on the spring plate and clamp until the snap-ring groove is exposed.
4. Insert snap-ring (4). The collar of the snap-ring must point towards the multiple-disc pack.
NOTE: Pay attention to sequence of discs. Place new friction multiple-discs in ATF fluid for one hour before installing.
5. Install disk spring (3) and multiple-disc pack (2) in outer multiple-disc carrier (8). (6) Insert snap-ring (1). (7) Measure the K3 clutch clearance.
a. Mount Pressing Tool 8901 (1) (Fig. 86) on outer multiple disc.
b. Using a lever press, compress pressing tool as far as the stop (then the marking ring is still visible).
c. Using a feeler gauge, determine the play "L" (Fig. 87) at three points between the snap-ring (8) and outer multiple-disc (2).
d. During the measurement the snap-ring (8) 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 (0.091 - 0.106 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 (8), 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).
