CHAPTER TWO
PREPARATION
SAFETY………………….. There are many dangers in the workshop,we cannot stress
enough the need for safety, you need to be aware of the inherent hazards surrounding you whilst
building and stripping mechanical components and in using electrically operated power tools.
The completion of this project is more easily embarked upon if you use common sense when
applying safety procedures and cleanliness in the work area as part of your routine before
and after and during the build process each day.
GRP. Glass reinforced plastic (fibreglass) is a hazardous material and adequate precautions
should be taken in its use and preparation,
HAZARDS.
I. Dust in the air from filing, drilling, cutting and sanding.
II. Sharp edges and splinters.
III. Fumes from resin.
WEAR PROTECTIVE CLOTHING ,FACEMASK and KEEP WORK AREA WELL
VENTILATED.
REMEMBER…
DO DON`T
Use eye protection when using power Attempt to lift heavy components without aid
tools,and when welding or under the always get help.
vehicle.
Take short cuts to finish a job.
Keep loose clothing and long hair out
of the way of tools and moving parts. Use damaged or ill fitting tools which may slip
and cause injury.
Remove rings wristwatches and any-
Thing that may get caught. Leave tools or parts or oil and fuel spills lying
Around always clean up.
Ensure that jacking equipment/axle
stands have sufficient load capacity. Allow children or pets near the vehicle whilst
it is supported on jacks/stands, or whilst using
If working alone get someone to check power tools/welding equipment
on you periodically
Smoke near inflammable chemicals
Make sure you have sufficient time to
complete tasks

DUST. Can cause irritation to the eyes and skin, block nasal passages and cause respiratory
Problems clean all work area after working with GRP. ie. After sanding, cutting and
Drilling.
EYES. Wear protective eye glasses whilst carrying out operations with electrical tools, such
As grinding, drilling, sanding.
FIRE. The workshop will be full of combustible materials and the fire hazard cannot be
Overstated, it is in your own interest to invest in a fire extinguisher and take simple
precautions to prevent the risk of fire.
I. NO SMOKING in the workshop.
II. ALL PETRO CHEMICALS stored in a steel locker/drawer
III. ELECTRICAL TOOLS unplugged and wire coiled neatly (trip hazard).
IV. RAGS AND PAINTBRUSHES used with chemicals (petrol/thinners) tidied away
so as not to be ignited by sparks from welding/grinding
SUPPORTING THE CAR. It cannot be stressed enough that the chassis/car is supported on
sturdy axle stands or ramps NEVER work on the vehicle only supported on a jack or unsuitable
items such as wooden blocks or bricks.
TOOLS………….
If you consider the outlay already on purchasing your AK, it is obviously worthwhile to invest
in adequate tools for the job in hand.
Depending on which jaguar was donor vehicle early cars were imperial, later cars metric, you
will require :
SOCKET SET. 3/8in to 1 ¼ in AF . or 10mm to 32mm. ½ inch drive with long and short
extensions and universal/wobbly joint attachment. 3/8 inch and ¼ inch drive sets would also
be useful.
COMBINATION SPANNERS 3/8 in to ¾ in AF. or 10mm to 19mm.s
SCREWDRIVERS various sizes, flat bladed and crosshead/posidrive.
MOLEGRIPS, ADJUSTABLE SPANNERS, ALLEN KEYS (hex wrenches) FILES, HAMMER
RUBBER MALLET and HAND DRILL
PLIERS. Various long nose, square jaw and circlip pliers(for internal/external circlips)
wire strippers/crimpers, side cutters.
STANLEY KNIFE, SPIRIT LEVEL, VARIOUS SAWS (for metal and wood).
ELECTRICAL TOOLS…. Grinder , sander, Drill and various bits.

AK SPORTSCARS
14
MISCELLANEOUS…….. tape measure/ruler , spirit level , marker pens, masking tape.
SPECIAL TOOLS…… pullers, spring compressors ( Hire shops are good source for these)
WORKSHOP/GARAGE.
Working on or around the vehicle requires space, a double garage is preferable but not
available to all, so consider your work area and storage facilities, room to lie on the floor and
stripping down of donor parts and storage of same.
Keep the floor areas clean and tidy, so consider shelving for storage, various containers for nuts/
bolts/screws and all the other bits and pieces you will acquire during the build process.
Also consider storage of tools and availability, a workbench is a bonus but workmate will suffice
you will also need the use of a vice and electrical sockets.
Invest in a FIRE EXTINGUISHER a fire blanket and a bucket of sand , you may need them !
IT IS ALSO ADVISABLE TO SECURE YOUR WORKSHOP.YOUR PROJECT IS VERY
VALUABLE AS ARE THE TOOLS TO BUILD IT.
With all this in place you are now ready to embark on your project.
THINK CLEAN : THINK TIDY
THINK SAFE

CHAPTER THREE
CHASSIS/BODY
CHASSIS SUPPORT/PREPARATION……
The chassis /bodyshell is received with the body temporarily fitted to the body, it is advisable
at this stage before removal of the bodyshell to mark the exposed chassis rails in the engine bay
with a piece of chalk, or to make a template of the engine bay area as this will assist in the
positioning/fitting of brake lines and fuel lines.
You will have also receive other items necessary for your build, namely nudge bar brackets,
shortened wishbones, roll bar brackets, various nuts and bolts for body to chassis fitment.
A full list can be seen in the chapter <YOUR AK 427>.
SUPPORTING CHASSIS.
The chassis needs to be on level ground, supported on axle stands and at a height to enable
getting underneath, to enable the correct set-up of the suspension components the chassis will
need to be level front to rear and side to side.
PAINTING CHASSIS.
The AK chassis is fully painted by AK unless specified by the customer that they wish to prepare
and paint the chassis themselves, you can also paint it again yourself at this stage if you wish.
BODYSHELL STORAGE…..
Removing the body from the chassis will require the help of a up to four able bodied people as
the bodyshell is heavy, store the body away unless you are dressing out the engine bay and/or
you are using a coloured gel coat and are preparing it yourself.
also some items that will need to be fitted to bodyshell before refitting to chassis, such as pedal
box and heater assembly.
IMPORTANT NOTE RE: BODY STORAGE. ONCE YOU HAVE REMOVED THE
BODY FROM THE CHASSIS IT NEEDS TO BE STORED ON A LEVEL SURFACE
WITH THE BOOT AREA SUPPORTED, TO ASSIST IN THIS YOU WILL FIND
WATCHING CLOSELY THE DOOR GAPS AND MAINTAINING THE GAP THAT
WAS APPARENT WHEN MOUNTED ON THE CHASSIS.

CHAPTER FOUR
RUNNING GEAR/SUSPENSION
GENERAL INFORMATION
DONOR VEHICLE.
The chassis of your AK has been designed to work with the suspension components and running
gear from the XJ6 and XJ12 Jaguar, post 1974 series 2 or 3 models.
SELECTION.
The purchase of a complete Jaguar donor vehicle is necessary as you will require the log book
from the vehicle, although it is possible to obtain parts required from vehicle dismantlers and
purchase a scrap jaguar for its logbook.
When selecting your donor vehicle, it is in your interest to select as low a mileage jaguar or one
that you have inspected the suspension components to ascertain the amount of refurbishment
required, it is also important to select a vehicle with the ventilated disc and four piston calliper
set-up as this is superior to the earlier solid disc and three piston caliper arrangement on earlier
cars.
You also need to take the final drive ratio into consideration and check it is suitable for your
engine/gearbox combination, refer to information in chapter <YOUR AK 427>.
FINAL DRIVE RATIO determines the acceleration and maximum speed of the vehicle, a high
figure (ie, 3:54:1) gives faster acceleration but lower maximum speed, a low figure (ie 2:88:1)
gives lower acceleration but higher maximum speed.
: IMPORTANT NOTE :
YOU MUST USE THE FRONT VENTILATED DISC
AND FOUR POT BRAKE CALIPER SETUP, THIS IS
FOR SAFETY AND SUPERIOR BRAKE EFFICIENCY
THE INFORMATION ON STRIP DOWN & OVERHAUL OF
SUSPENSION COMPONENTS IS INTENDED AS GUIDANCE
ONLY, YOU MUST USE THE RELEVANT WORKSHOP
MANUAL AS THE PRIME REFERENCE

AK SPORTSCARS
18
The suspension components are mounted in subframe assemblies, you need to remove these
from the donor vehicle first, then remove the suspension components and brake components
from subframes, rusted nuts and bolts are best soaked overnight if possible with penetrating
oil or similar to aid the strip down procedure, wire brushing around nuts bolts and threads
will aid removal and make the task a lot easier.
FRONT SUSPENSION STRIPPING/PREPARATION.
Work on one side at a time, begin with the removal of the brake calipers and discs, you will need
coil spring compressor for next step, removal of coil spring,
After removal of the six retaining bolts holding spring platform to lower wishbone remove the
spring, undo nuts securing upper and lower ball joints separate from stub axle carrier and
remove carrier. Remove both wishbones; the upper wishbone is in two halves; also note carefully
the position and number of camber shims for replacement during rebuild.
Repeat procedure for the other side.
Clean all components with paraffin and wire brush ready for painting, do not paint bearing
surfaces, use an enamel or hammerite or have parts powder coated,
make a list of parts that will need replacement.
You will not require the following parts: dustshield / steering arm / shock absorbers / anti roll
bar / subframe. refer to diagram front suspension, as some of the above parts are AK
replacement items.
When reconditioning/rebuilding the front suspension, it is advisable to renew as many of the
items listed below as possible for your own safety, they are in all likelihood worn and need
replacement.
ie: upper and lower ball joints / bearings and races / bushes /new ventilated discs / refurbished
exchange calipers.
REAR SUSPENSION STRIPPING/PREPARATION.
Remove the suspension components from the subframe first, this will involve the removal of the
tie plate which is under the final drive housing and ties the subframe together, the bolts securing
this plate are invariably rusty, the six bolts into the subframe halves can be chiselled or ground
off, the bolts which fix the plate to the final drive housing need to be unscrewed as once the final
drive is placed into the AK chassis a metal plate is fixed to the underside of the final drive
housing to protect fuel line which runs under the housing.
:WARNING:
THE FRONT SPRINGS ARE UNDER A GREAT DEAL OF TENSION
UNTIL THE PRESSURE IS RELIEVED HANDLE WITH CARE AS
THIS EXERCISE CAN BE DANGEROUS

AK SPORTSCARS
19
NOTE: remove the top centre bushes from the rear shock absorbers, you will
require them for fitment of the front shock absorbers when rebuilding.
Keep the shims from drive shafts to disc, as these are required for camber set-up, and the shims
from the inner pivot mounting.
The driveshaft universal joints will need to be removed and the driveshaft flange and splined
yoke kept, the driveshafts are returned to AK for shortened items along with the wishbones.
The bolt and bush holding the original pressed steel radius arm in position are also required for
fitment of radius arms supplied by AK, you will notice the bolt has half of the hexagonal head
removed; this is so it will pass the shock absorber flange, retain this bolt and bush.
make a list of parts that will need replacement.
You will not require the following parts: radius arms / shock absorbers / coil springs / subframe.
When reconditioning/rebuilding the rear suspension, it is advisable to renew as many of the
items listed below as possible for your own safety, they are in all likelihood worn and need
replacement.
ie: driveshaft Ujs / Lower wishbone needle rollers / rear discs / hub carrier bearings /
refurbished exchange calipers.
Drain gear oil from final drive/differential .
The final drive /differential examine for any pinion backlash, renew the two driveshaft output
seals and the front input seal (there is no need to dismantle the differential to do this).
Clean all components with paraffin and wire brush ready for painting, do not paint bearing
surfaces, use an enamel or hammerite or have parts powder coated.
READY TO REBUILD
With all donor parts refurbished and necessary components replaced with new items, along with
the exchange driveshafts and wishbones from AK, you should also have purchased the six coil
over shocks required and can now rebuild the front and rear suspension assemblies and fit them
to AK chassis.
: PLEASE NOTE :
AK WILL SUPPLY YOU WITH SHORTENED REAR WISHBONES
AND DRIVESHAFTS ON AN EXCHANGE BASIS.
