(6) Separate piston guide ring (13) and the B2 pis-
ton (10) from the B3 piston (8) by blowing com-
pressed air into the bore (D) (Fig. 130).
(7) Press piston guide ring (13) out of the B2 pis-
ton (10).
(8) Separate piston guide (4) from the B3 piston
(8) by blowing compressed air into the bore (A) (Fig.
130).
ASSEMBLY
(1) Assemble piston guide (4) (Fig. 131) and B3
piston (8) in the correct position.
(2) Check all sealing rings (Fig. 132), replace if
necessary. The rounded off edges on the sealing rings
(6), (3) and (2) must point outwards. The rounded off
edges on the sealing ring (4) must point inwards.
(3) Insert B2 piston (10) (Fig. 131) in B3 piston (8).
(4) Insert piston guide ring (2) (Fig. 133). The
valve (1) in the piston guide ring must be on top.
(5) Insert disc spring (14) (Fig. 131) and spring
plate (15). Insert disc spring with the curvature
towards the spring plate
(6) Place Multi-use Spring Compressor 8900 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. 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 (8)
must contact the upper bearing surface of the
groove in the outer multiple-disc carrier.
(10) Measure the B2 clutch pack clearance.
(a) Mount Pressing Tool 8901 (1) (Fig. 134) on
outer multiple disc.
(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

(Fig. 135) at three points between the snap-ring (8)
and outer multiple-disc (7).
(d) The correct clutch clearance is 1.9-2.3 mm for
the four friction disc versions and 2.0-2.4 mm for
the five disc versions.
(e) Adjust with snap-ring (8), if necessary. Snap-
rings are available in thicknesses of 2.9, 3.2, 3.5,
3.8 and 4.1 mm.
