Assembly is made with strict regard to the
markings on certain parts to ensure that
they are returned to the same relative
position.
(i)
Fit a rubber bush to each end of the
upper fulcrum pin.
RUBBER BUSHES
(ii)
Feed the fulcrum pin into the upper
wishbone arm, press the second rubber
bush into the wishbone and fit the large
plain washer followed by the castellated
nut. This nut should be left loose at
this juncture.
(iii)
While similarly fitting the second wish-
bone arm ascertain that the other ends
of the arm are positioned correctly to
receive the ball pin assembly and dis-
tance piece. With the ball pin assembly
toward the operator the wishbone
flange on the right overlaps the one
on the left. This applies to both left
and right suspension units.
(iv)
Feed through the upper attachment
of the ball joint assembly with the
distance piece between the wishbone
arms and secure with the plain washer
and castellated nut locked by the split
pin. Tighten castellated nuts of inner
upper fulcrum pins and lock with
split pins.
(v)
Fit the ball pin taper into the
vertical
link
with the rubber gaiter in
position and secure with the plain
washer and castellated nut. Fit split
pin in nut.
(vi)
Offer up the inner upper fulcrum pin
to the chassis frame and secure by bolts
with a plain washer under its head and
a lock washer with the nut at the points
near the centre line of the car. Set-
screws and lock washers are used for
the attachment points nearer the ball
ioint assembly.
