9.8.3) Link arms to chassis
With the De Dion tube in place attach the
forward link arm to the upper mounting
bush on the chassis using caphead bolt
(fastener pack 30R011A Item 2) pass
from inside the cockpit, through the link
arm. Secure using nyloc nut (8) and plain
washer (14).
The rear link arm attaches to the rear of
the wheel arch into a plain boss. Secure
the rear link arm to the boss using bolt
(fastener pack 30R012C Item 2) nyloc nut
(4) and plain washer (7). Hold link arms
horizontally and tighten to 34 Nm.
9.8.4) Bellcrank to Di Dion tube
Drop the bellcrank into the vertical flanges
on top of the De Dion tube. It should be
noted that the bellcrank is secured using
an M10 bolt but the vertical flanges have a
1/2" hole for traditional radius arm fitment.
Two bellcrank spacers are used on the
inner sides of the flanges to centre the
bolt in the hole, refer to Figure 128.
Assemble the bellcrank into the vertical
flanges ensuring that the two bellcrank
spacers are correctly located; pass bolt
(1) and plain washer (7) inboard through
the vertical flanges. Secure with nyloc nut
(4) and plain washer (7). Tighten to 34
Nm. It is essential that plain washers are
used on the outside of both flanges in
order to pass the load to the flanges
rather than the bellcrank spacers.

the colour dot on the rear anti-roll bar.
Apply rubber lubricant to the centre of the
bushes and slide them down over the flat
