Ensure to fit a rubber grommet in the hole

Since access to the upper and lower

wishbone mountings are restricted by

other components installed later in the

build process the mounting fasteners must

be fully tightened at this point. Hold the

wishbones horizontal and tighten the

upper wishbone mounting bolts/nuts to 34

Nm and the bottom wishbone to 81 Nm.

NOTE

Check that there is an equal amount of

exposed threads between the locknut and

ball joint, this should be adjusted to eight

threads for normal road use

5.4) Spring damper units

An aluminium spacer bush 8 mm id x 1/2”

od x 32 mm (polythene bag marked ‘front

suspension’) must be coated in copper

slip and inserted into the top mounting

bush of the front spring damper unit. The

spring damper is secured to the top

mounting by the M8 cap head bolt

supplied in the chassis with a spring

washer (13) under the bolt head. This bolt

should be torqued to 20 Nm.

NOTES

It is necessary to gently press the body

panel inwards to allow sufficient clearance

for the bolt to be located.

An aluminium spacer 8 mm id x 1/2”

od x 32 mm must be coated in copper slip

and inserted into the lower mounting bush

of the spring damper unit. The spring

damper unit is secured using an M8

caphead bolt (supplied in wishbone) which

passes through the rear leg of the lower

wishbone through the aluminium spacer

bush and into a captive thread on the front

leg. This bolt should be torqued to

20 Nm.

NOTE

Do not tighten any other fixings at this

stage
