Steering linkage-To dismantle
I.
The linkage can
be
readily dismantled by re-
moving the split pins and nuts from the ball joints
and extracting the pins from their sockets using
extractor (RH 8080).
Ball joints--To renew
The ball joints are fitted with grease nipples and can
be dismantled and renewed if necessary.
1. To facilitate removal of any link assembly, the
car should
be
placed on a ramp or over a pit; alter-
natively the front of the car should be jacked up.
2.
Remove the split pin and castellated nut from
the ball pin end, and using the special tool
(RH 8100),
extract the ball pin from the eye of the lever. Remove
the ball pin from the opposite lever eye in a similar
manner.
3.
Remove the plug retaining the ball pin and collect
the seal washer; the spring, spring seat and steel ball
can then be removed together with the ball pin.
4. The rubber seals between the socket and lever
eye should always be renewed if the joints have been
disturbed.
5.
A press must be used to remove and fit the ball
seat, which is squarely pressed in position against the
socket shoulder. The pressure required to fit the seat
should be between 800 lb. and 1250 lb.
(402,8 kg. and
566,9 kg.).
It
is important not to damage the cham-
fered top edge of the seat during the pressing opera-
tion, otherwise the sealing feature of the seat will be
destroyed.
6.
When the seat has been pressed squarely into
position the ball pin should be lightly lubricated with
an approved grease and inserted, followed by the
steel ball, spring seat and the spring. Fit the aluminium
joint washer and the plug.
7.
Repeat this procedure to install any other ball
pins which require renewal.
8.
Check that all seal faces are free from burrs,
then fit the seal and spring, after applying
Roc01
T
265
grease to the seal faces. Ensure that the tapers of the
ball pins are free from lubricant, then locate the ball
pin tapers in position; torque tighten the castellated
nuts to between 35 lb. ft. and
40 lb. ft. (4,84 kg.m. to
5,53
kg.m.) and fit the split pin.
Note The seals fitted to the inner ends of the
cross-tubes are not secured to the cross
steering tube track rod ends.
9.
Using Wanner grease gun
(RH
7202), lubricate
the ball joints with the approved grease (see Chapter
D),
until it exudes from the seals.
10. Each joint will require approximately
4
oz. (93
gm.)
of lubricant for the initial filling operation, but
this quantity will be reduced for periodic servicing.
Note It will be noted that the steering cross-
beam ends have a
20" 'set' and if the
cross-beam is removed, care must be
taken to replace it in the correct position
i.e. with the 'set' pointing towards the
rear of the car
(see
Fig.
N38).
Care must
be taken when fitting the track rods to
ensure that the adjustable end is placed
outwards towards the wheels.
11. Both of the adjustable ends of the track rods are
right-hand threaded for adjustment of the toe-in.
Toe-in must always be checked whenever any replace-
ment parts have been fitted to the track rods.
Steering idlerldamper-To remove
The steering idlerldamper can be removed from the
car without disturbing the rest of the steering linkage.
1.
Place the car on a ramp.
2.
Disconnect the battery.
3.
Remove the front exhaust pipe assembly.
4.
Support the engine with either a sling or a jack
and wooden pad.
5.
Remove the two nuts and washers securing the
engine front mounting.
6. Remove the nuts and bolts securing the steering
box pipes to the front engine cross-member
7.
Remove the split pin and nut from the idler/
damper lever joint on the steering cross-beam then,
using extractor (RH
8100) partially extract the ball
pin from the lever.
8.
Remove the four bolts, nuts and washers securing
the engine cross-member to the steering box and the
steering
idlerldamper housing; remove the cross-
member.
9.
Remove the three setscrews and washers securing
the steering
idlerldamper box to the sub-frame.
Steering idlerldamper-To dismantle
(see
Fig.
N39)
1.
Clean the housing to remove all traces of dirt.
2.
Remove the filler plug and the plug from either
end of the cylinder bore; drain the fluid.
3.
Unscrew and remove the washers and nuts
securing the
ccver of the lever access hole then
remove the cover together
with the joint. Discard
the joint.
