B2 Clutch - Assembly

ASSEMBLY

Special Tools:









Holding Clutch B2/B3 Seals





1. Check all sealing rings (2-4, 6), replace if necessary. The rounded off edges on the sealing rings (2, 4, 6) must point outwards.




Holding Clutch B2





2. Assemble piston guide (4) and B3 piston (8) in the correct position. Verify that the missing tooth in the B3 piston/B2 outer disc carrier (8) is aligned with the centerline of the two threaded holes in the B2 and B3 piston guide (4).
3. Insert B2 piston (10) in B3 piston (8).










4. Insert piston guide ring (2). The valve (1) in the piston guide ring must be on top.

5. Insert disc spring (14) and spring plate (15). Insert disc spring with the curvature towards the spring plate
6. Place Multi-use Spring Compressor on the disc spring (14) and compress the spring until the groove for the snap-ring is exposed.
7. Insert snap-ring (16).

NOTE: Pay attention to sequence of discs. If the original clutch discs are reused, be sure to return the disc identified on disassembly as belonging on top of the disc spring (3) to its original location. Place new friction multiple-discs in ATF fluid for one hour before installing.

8. Insert disc spring (3) and multiple-disc pack (2) in the B2 outer multiple-disc carrier.
9. Insert snap-ring (1).










NOTE: During the measurement the snap-ring must contact the upper bearing surface of the groove in the outer multiple-disc carrier.

10. Measure the B2 clutch pack clearance by mounting the Pressing Tool (1) on outer multiple disc.
11. Using a lever press, compress pressing tool to the upper most line marked 1200 N (the marking ring is still visible, see small arrow).










12. Using a feeler gauge, determine the play "L" at three points between the snap-ring (8) and outer multiple-disc (7).
13. The correct clutch clearance is 1.9-2.3 mm (0.075-0.091 in.) for the four friction disc versions and 2.0-2.4 mm (0.079-0.095 in.) for the five disc versions.
14. Adjust with snap-ring (8), if necessary. Snap-rings are available in thicknesses of 2.9 mm (0.114 in.), 3.2 mm (0.126 in.), 3.5 mm (0.138 in.), 3.8 mm (0.150 in.), and 4.1 mm (0.162 in.).
