seat adjustment JAGUAR XJ6 1994 2.G Workshop Manual

10.1 STEERING SYSTEM DESCRIPTION
10.1.1 Steering Column Major Components
Integrated column assembly incorporating power, or manual, reach /tilt mechanism and lock.
Ignition switch.
Ignition interlock solenoid.
Key transponder coil.
Body attachment points.
Depending upon model, the steering column may be adjusted for
tilt and reach, either by electrical or manual means.
Power variants may be either automatically or manually adjusted and all types have the entry / exit feature.
10.1.2 Steering Column Operating Principle
Power Adjust: Two independent motor / gearbox assemblies provide infinite adjustment for reach and height within
approximate ranges of 35mm and
13O respectively. Adjustments may be automatically made in conjunction with the
seat memory facility or manually when the adjustment switch is used. It should be noted that selection of 'Off will
disable the automatic entry / exit mode.
Manual Adjust: The cable operated reach adjustment is infinite within a range of 35mm, with the desired position being
fixed
by a rack and wedge. Tilt variations are stepped at approximately 3O intervals with 6 positions being available,
the uppermost being unlatched.
From the uppermost position the column may be pulled down to engage the first detent without using the
tilt lever.
WARNING: MANUAL ADJUST ONLY: TO AVOID PERSONAL INJURY, COLUMN UPWARD TRAVEL SHOULD BE MAN- UALLY RESTRAINED TO CHECK UPWARD SPRING ASSISTANCE. THIS IS ESPECIALLY IMPORTANT IF
THE STEERING WHEEL HAS BEEN REMOVED FOR MAINTENANCE REASONS.
WARNING: ALL TYPES; DO NOT REMOVE THE STEERING COLUMN FROM THE VEHICLE WITH THE STEERING
WHEEL ATTACHED UNLESS THE STEERING
IS CENTERED AND THE COLUMN LOCK IS ENGAGED. IFTHE
SERVE THIS MAY RESULT IN AN INOPERATIVE AIRBAG SYSTEM. SEE LABEL ON STEERING WHEEL

Assembly
. Bearing. Assemble the inner bearing track to the hub using service tool 18G 134 and adaptor JD 550 - 5 / 1.
Ensure that the hub inner seal diameter is free of debris or damage and is lightly lubricated prior to assembly.
Only replace complete bearings, never cup or race in isolation.
Assemble the outer bearing cup to the hub using service tool
18G 134 and adaptor JD 550 - 5 / 2. Pack each race with approximately 4 ml of grease and position the inner race onto the stub axle.
Apply a smear of grease to hub inner surfaces and bearing cups. Assemble the hub to the stub axle followed by
outer race, bearing washer and hub nut.
It is not necessary to fill the hub cavity with grease, merely protect from corrosion with a coat of IubricanL'Seat'the bear-

. End float. Set a Dial Test Indicator (DTI) as shown in Fig. 1 and adjust the hub nut to achieve the correct end float.
As the adjustment is made, continually load the hub axial-
ly in both directions.
. Without disturbing the end float setting, fit the castellated
nut retainer so that it aligns with both hub nut and stub
axle drilling.
. Secure nut retainer using a new cotter pin.

and operation of the braking system verified.

Suspension Systems
Fig. 1 Rear Suspension layout
11.3 REAR SUSPENSION, DESCRIPTION
The vehicle's rear suspension layout features a cast wishbone complete with integral lower spring pan (1 Fig.1) sup- porting the independently mounted damper (2 Fig.1) and road spring (3 Fig.1).
Thelowerwishbonearmis boltedtothehubcarrier(4 Fig.1) by meansofa pivot bolt (5Fig.l),allowingfortoe-in adjust- ment. When the pivot bolt is seated correctly in the plate located on the wishbone arm, it has a small clearance at the
sides but full clearance at the top and bottom.
Rotation of the bolt head, with eccentric constrained between the vertical faces, causes the bolt shank to be moved in
the horizontal plane, thus displacing the hub carrier and effecting wheel alignment adjustment.
The snubber
(6 Fig.1) positioned above the hub carrier, prevents this from touching the vehicle body.
The hub
carrier/wishbone assembly, is pivoted on the wishbone fulcrum bolt (7 Fig.1) and is then secured by a nut and
washerfixing arrangementtothe pendulum assembly (8 Fig.1) andthe wishbonetie assembly (9 Fig.l).The differential
strut (10 Fia.1) is fastened to the wishbone tie assemblv and to a bracket, welded to the vehicle bodv. Both, the pendu- lum and the wishbone tie assembly are fitted to the differential unit which is mounted on to a mounting frame and a rear frame carrier.
The supercharged vehicle (manual only), the XJ12 and the sport versions are equipped with
a rear stabilizer bar, a dif- ferential monostrut instead of two single struts, a modified wishbone tie and two stabilizer bar drop links which are
seated on the lower wishbone cast bosses.

13.8 SEATING AND SEAT BELTS
13.8.1 Seating, Description
The front seats are available in a range of materials consisting of sculptured fabric / leather, leather, sports cloth / leather, embossed leather / leather and autolux. Both seats are available as 'manual', ie manually adjustable with elec- tric rise and fall, manual height adjustment headrests, 'power', ie 12-way electric adjustment, 'power with memory', ie memory controlled, 12-way electric adjustment of seat, steering column and exterior rear view mirrors and 'heated',
ie with integral heating.
Front seats are based on a non
-handed, one-piece frame which includes cushion and squab frames and seat adjuster
mechanisms. The seat switchpacks (powerseats) are fitted to the outboard side of driver and passenger seats; on 'man- ual'seats, the seat height adjustment switch is similarly located. Seat control modules SCMs are contained within the
seat assemblies. The seats are secured through four mounting points to the vehicle floor.
Rear seats are of the bench type with
full width removable cushion and individual seat squabs.
Electrical components installed on the heel board below the rear passenger seat are protected
by two covers secured
by two locating brackets on the floor and by two latches on the cover. The latches are released by pushing down on
the two recesses in the top edge of the cover.
