Seat belts
The seat belts can now be fitted using the brackets and fastenings supplied, You will find a long tube adaptor
for the lower mount and a top hat adaptor for the upper mount, the upper mount needs to be able to swivel so
if its too tight remove and add a spacer washer behind the spacer. The seat belt retainer catches are best fitted
with a spacer through the floorboard against the chassis, this will stop the seat belts coming loose as the
floorboard settles.
12.6
Chassis plate
The chassis plate is usually mounted on the left hand bulkhead under the bonnet using four 3 mm pot rivets,
check details are correct before riveting.

Ignition Setting, Carburetion, Testing Running and Tuning
Safety point: Before proceeding check that there is no spilled fuel which could be ignited, and that the fuel
pump is disconnected until ready to start, This can be done by removing the fuse in the fuel pump relay.
Ignition key must be switched off unless otherwise stated.
13.1
Ignition Settings
13.1.1 Oils and water
Make sure the engine, gearbox and rear axle have oil to the appropriate level and the radiator is filled with
water and antifreeze, keep an eye on the water level through the first time the engine runs as the level can
drop as the air comes out of the engine. See appendix 6.
13.1.2 Static timing
If fitted remove all spark plugs and disconnect the high tension lead from the coil for safety, Turn the engine
over by turning the crankshaft or pushing with the car in forth gear until you can feel pressure building up
with your thumb over spark plug hole number one (rearmost plug) this will be the compression stroke.
Continue turning until the crankshaft pulley marks line up with the pointer on the timing chain cover at the
correct point BTDC for you engine (e.g. for 4.2 engine static timing is 8degrees Before Top Dead Centre).
13.1.2 Setting contact breaker points
Ignore if you have electronic ignition. Turn the crankshaft or distributor until one of the distributor camshaft
high points is central on the heel of the points (the easiest way to do this is to engage fourth gear and rock the
car forwards or backwards). Once in this position you can slacken the screw that holds the points before
adjusting the gap and measuring with some feeler gauges, the gap should be 0.014 to 0.016 inch.
13.1.3 Setting distributor
Slacken the distributor clamp bolt and connect a test lamp from chassis earth to the negative contact on the
coil. Switch on your cars ignition and turn your distributor clockwise until the light comes on, this tells us
that your contact breaker points have just opened. You can now tighten the clamp bolt and fit your rotor arm
and distributor cap. Switch the ignition off.
13.1.4 Spark plugs and HT leads
You can now refit your spark plugs, check they are gapped correctly for your plug and engine type. You can
also refit your plug (HT) leads, the firing order on the XK engines are 1 5 3 6 2 4, number one plug is at the
rear of the engine and should be connected to the distributor cap in the position that the rotor arm is currently
pointing to, its normally at about 10 o'clock position. The distributor turns anti clockwise so number 5 is
next to number 1 going anti clockwise and so on.
