(a) Mount Pressing Tool 8901 (1) (Fig. 77) on
outer multiple disc.
(b) Using a lever press, compress 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
(Fig. 78) at three points between the snap-ring (5)
and outer multiple-disc (3).
(d) During the measurement the snap-ring (5)
must contact the upper bearing surface of the
groove in the outer multiple-disc carrier.
(e) The correct clutch clearance is 2.7-3.1 mm
(0.106-0.122 in.) for three friction disc versions,
3.0-3.4 mm (0.118-0.134 in.) for four disc versions,
3.3-3.7 mm (0.130-0.146 in.) for five disc versions,
and 3.6-4.0 mm (0.142-0.158 in.) for six disc ver-
sions.
(f) Adjust with snap-ring (5), if necessary. Snap-
rings are available in thicknesses of 2.6 mm (0.102
in.), 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.).
