Refers to item (22). Screw the ball housing locking
ring onto the rack end as far as it will go and refit
the lock washer. On models not fitted with a lock
washer, fit a new locking ring. Refit the seat spring,
seat, tie-rod and ball housing, and tighten up until
the tie-rod
is
pinched. Slacken the housing one-
eighth
of
a turn and tighten the locking ring to the
recommended torque. Punch the lock washer into
the slots
of
the housing and locking ring.
If
no lock
washer is
fitted, punch the lips
of
the locking ring
into the slots
of
the ball housing and rack.

type). Refit the yoke with
the disc springs but without the packing shims.
With the rack in the straight-ahead position,
tighten the cover screws until
it
is
just possible
to rotate the pinion with the pre-Ioad gauge,

Measure the gap between the damper housing
flange and the rack housing. Remove, and then
refit the damper with shims to the thickness
of
the measurement minus ·002 in. (,05 mm.).

Refit the rack to the body with the 'u' bolts lightly
tightened to allow the pinion to accept the column
alignment.

FRONT

ALIGNMENT
Checking
When checking
or
adjusting the front wheel alignment
it
is
essential to use equipment designed to work
at
the
specified height and diameter, and preferably a gauge
which measures the angles involved rather than the
difference in distance between the wheels in front
of
and behind the centres.
With the car unladen, tyres
at
the correct pressures, and
the steering in the straight-ahead position, each wheel
should make an angle
of
7'
30"
with the longitudinal axis
