I
Important

Warning
Lengthy and repeated contact with mineral oil removes
the natural oils of your skin, drying it out and causing
irritation. If oil has been swallowed, do not provoke
vomiting. Call a doctor.
Waste oil may contain harmful impurities which can
cause skin cancer. Always use suitable protection and
thoroughly wash your hands and other areas of bare
skin that have come into contact with the oil.
Observe the following safety rules:
• Avoid lengthy and repeated contact with oil,
grease, etc. And especially waste oil.
• Wear protective clothing, including impermeable
gloves, if possible.
• Do not put oily rags into your pockets.
• Do not wear clothes that have been soiled by oil,
especially items of underwear. Clothes must be
washed at regular intervals.
• Do not wear oily shoes.
• Clean open sores immediately and cover them
with an adhesive bandage, sticking plaster, etc.
• Use barrier cream. Apply it to your exposed skin
before each working period so that it will be easier
for you to wash oil and grease off afterwards.
• Remove oil from your face and hands, etc. by
washing them thoroughly with soap and water
(special skin cleansers and a nailbrush will help).
• Do not use petrol, paraffin, diesel oil, thinner or
solvents to remove oil from any part of your body.
• If you notice any changes in your skin, consult a
doctor without delay.
• If possible, clean the parts before starting work.
• If there is a danger of oil getting into your eyes,
wear protective goggles, a visor or a face mask.
Eye-washing equipment must also be readily
available.

Technical description

Engine
The XU7 JP is a four-cylinder, in-line engine mounted
transversely at the front of the car, with two valves per
cylinder operated by a single overhead cam. The
cylinder block is of a light alloy with a cast iron
crankshaft incorporating eight balancing masses the
connecting rods are fitted with extra-flat pistons. The
timing is driven by a notched belt of high heat resistant
materials. The accessories are driven by a single
multiple vee-section belt with constant pressure being
supplied by an automatic tensioner.
The engine is equipped with a Magneti Marelli 8p fuel
injection system with the injection manifold being part of
the air inlet manifold.
XU7JPK - Sagem SL96
W72D001 XU7JPL3 - Sagem S2000

Cylinder Block
The cylinder block is cast in aluminium alloy, and the
bores have replaceable cast-iron liners that are located
from the top of the cylinder block. Sealing ‘O’ rings are
fitted to the base of each liner, to prevent the escape of
coolant into the sump.

W72D002
20 Technical description

Pistons
The pistons are made of light alloy and have grooves
for two compression rings and one scraper ring.
The top compression ring has a chromed radius, the
second compression ring has an oil-scraper function.
The scraper ring incorporates an expander.

W72D003

Connection rods
The connecting rods rotate on horizontally-split bearing
shells at their big-ends, these bearing shells are
replaceable. The pistons are attached to the connecting
rods by gudgeon pins. The gudgeon pins are an
interference fit in the connecting rod small-end eyes.

W72D004

Crankshaft assembly
The crankshaft is made of cast iron and has eight
incorporated balancing masses. The crankshaft runs in
five main bearings with thrust washers fitted to number
two main bearing cap to control crankshaft endfloat.
The crankshaft rotates on horizontally-split bearing
shells at main bearings, these bearing shells are
replaceable.

Cylinder head and camshaft


The camshaft is driven by a toothed timing belt, and
operates eight valves via followers located beneath
each cam lobe. The valve clearances are adjusted by
shims positioned between the followers and the tip of
the valve stem. The camshaft runs in bearing caps
which are bolted to the top of the cylinder head. The
inlet and exhaust valves are each closed by coil
springs, and operate in guides pressed into the cylinder
head. The cylinder head gasket is asbestos free.

W72D006

Lubrication
Lubrication is by means of an oil pump which is driven
via a chain and sprocket from the crankshaft right-hand
end. It draws oil through a strainer located in the sump
and forces it through an externally-mounted filter into
the galleries of the cylinder block. From there, the oil is
distributed to the crankshaft main bearings and
camshaft. The big-end bearings are supplied with oil via
internal drillings in the crankshaft, the camshaft
bearings also receive a pressurised supply. The
camshaft lobes and valves are lubricated by splash, as
are all other engine components.
