, on the vertical track member (7), slacken the two top grubscrews (8) and
pull out the two top pins (29). An M3 screw may be installed in the pins to assist in removal. Note the
position of and retain all shims (18).
13.4 On the mechanism housing (10), slacken the two top grubscrews (8) and pull out the two pins
(9). An M3 screw may be installed in the pins to assist in removal. Note the position of and retain all
shims (18).
13.5 Remove the two platform pivot blocks (5). If required, the plain bearings (6) may be removed by
slackening screws (3).
13.6 At the LH and RH actuators (32, 40), slacken screws (30).
13.7 Pull the bevel pinion shaft (35) sharply outwards to unseat the RH actuator shaft (34) and
bearing (12).
13.8 At the bevel pinion (39) unscrew the two grubscrews (38) until the shaft (35) can be pulled out of
the mechanism housing.
13.9 Remove the RH actuator shaft (34), complete with bearing (12), two snap rings (36) and flanged
bush (37). Dismantle as required.
13.10 Lift out the vertical track member (7) together with the LH and RH actuators (32, 40). To remove
the actuators, slacken the two bottom grubscrews (8) and pull out the two bottom pins (29). An M3
screw may be installed in the pins to assist in removal. Note the position of and retain all shims (18).
13.11 If required, the plain bearings (6) may be removed from the actuators (32, 40) by slackening
screws (30).
13.12 Pull the adjuster assembly (14) and two shims (13) out of the mechanism housing. Recover
bevel pinion (39) if not already removed.
, remove three screws (1, 15, 16) securing LH support cap (18 or 20) to base
(17).
, remove three screws (26, 27, 29) securing RH support cap (1) to base (28).
13.15 Lift the mechanism housing and support caps off the base, manipulating brake mechanism
through base aperture.
13.16 Pull the LH and RH support caps off the linkage. Note the position of and retain any shims (item
39,
). The bushes (item 19,
and item 25,
) are a push fit in the support caps.
, carefully support the upper drive arm (15) and drive in two horizontal track
arm pins (16), taking care not to damage the bearings in the horizontal track arm (17).
13.18 On the mechanism housing, release two grubscrews (8) securing upper arm pivot pins (22). Pull
out the two pins. An M3 screw may be installed in the pins to assist in removal. Remove the upper drive
arm (15). Note the position of and retain all shims (18).
13.19 On the mechanism housing, pull out the two lower arm pivot pins (29). An M3 screw may be
installed in the pins to assist in removal. Retain all shims (18).
NOTE:
An extended 4 mm AF spherical-ended hex wrench (Vinten Part No.
) is
required to remove the support caps
