Holding Clutch B2
HOLDING CLUTCH B2ASSEMBLY
1. Assemble the B2 and B3 piston guide (4) and the B3 piston/B2 outer disc carrier (8) in the correct position.
2. Check all of the sealing rings, replace if necessary. The rounded off edges on the sealing rings (6), (11), and (12) must point outwards. The rounded off edges on the sealing ring (9) must point inwards.
3. Insert the B2 piston (10) in B3 piston/B2 outer disc carrier (8).
4. Insert the piston guide ring (2). The valve (1) in the piston guide ring must be on top.
5. Insert the piston back pressure disc spring (14) and the spring plate (15). Insert the disc spring with the curvature towards the spring plate.
6. Place Special Tool 8900 on the disc spring (14) and compress the spring until the groove for the snap-ring is exposed.
7. Insert the snap-ring (16).
Note: Pay attention to the sequence of the discs. Place new friction multiple-discs in ATF fluid for one hour before installing.
8. Insert the disc spring (3) and the multi-disc pack (2) in the B3 piston/B2 outer disc carrier (8).
9. Insert the snap-ring (1).
Note: During the measurement the snap-ring (1) must contact the upper bearing surface of the groove in the outer multiple-disc carrier.
10. Measure the B2 clutch pack clearance.
a. Mount Special Tool 8901 (1) on the B3/B2 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 (8) and outer multiple-disc (7).
d. The correct clutch clearance is 1.9-2.3 mm (0.0750.091 inch) for the four friction disc versions and 2.02.4 mm (0.079-0.095 inch) for the five disc versions.
e. Adjust with snap-ring (8), if necessary. Snap-rings are available in thicknesses of 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).
