HOLDING CLUTCH B1ASSEMBLY
1. Install the piston (2) in the outer multiple-disc carrier (1). Press in the piston using the disc spring (3) and Special Tool 8900. Place Special Tool 8900 on the disc spring (3) and compress until the groove of the snap-ring (4) is exposed
Note: Check the vulcanized gasket, replace if necessary.
2. Insert the snap-ring (4).
Note: The collar of the snap-ring must point towards the multiple-disc pack. After installing, check the snapring for correct seat.
3. Insert the disc spring (5) and the multiple-disc pack (6) in the multi-disc holding clutch B1 outer carrier.
4. Insert the snap-ring (7).
Note: Pay attention to the sequence of discs. Place the new friction multiple-discs in ATF fluid for one hour before installing.
5. Measure the multi-disc holding clutch B1 clearance.
a. Mount Special Tool 8901 (1) multi-disc holding clutch B1 outer 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 (4). During the measurement, the snap-ring (6) must contact the upper bearing surface of the groove in the outer multiple-disc carrier (5). The correct clearance is 2.3-2.7 mm (0.091-0.106 inch) for 2 friction disc versions, 2.7-3.1 mm (0.106-0.122 inch) for 3 disc versions, and 3.03.4 mm (0.118-0.134 inch) for 4 disc versions.
d. 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).
