maintenance FORD SIERRA 1986 1.G XR4 Workshop Manual

pA Constant Velocity Joints & Boots The Merkur XR4Ti and Scorpio
independent rear axle assemblys utilize half shafts that have inner and outer constant
velocity joints. Eventually these joints and protective boots will require service. We
have joints and boots available separately making it economical to replace just the
worn component without having to replace whole axle assembly. However, if more
than one C.V. per axle requires service, our complete axle assembly is the more cost
effictive way to go.
Note: right/left inboard and outboard C.V. joints and boots are
interchangeable- see price list for complete axle prices (handed left & right)

Rubber Drive Shaft Coupling The rubber "Drive Donut" or "Rotoflex
Coupling" on the XR4 and Scorpio drive shaft can be a real bugger. Many owners
have contacted us after being quoted up to 500.00 to totally replace the complete
drive shaft assembly by the local Ford L/M dealer, as they do NOT list the rubber
drive coupling as a separate service part. We import the proper replacement
drive coupling and make it available at considerable savings to you. If your car
exhibits a driveline shudder that increases with speed, (especially noticeable in
colder weather) we recommend taking a close look at the condition of the drive
coupling. Cracks in the rubber or missing pieces will require immediate replace-
ment, loosing one of these joints at speed will be very messy !
Note: BAT supplies
the standard equipment XR4i drive coupling by the original supplier to Ford. This
is not a lesser "fits all" component that just happens to be similar.

Quaife Torque Biasing Differential Quaife torque biasing
differentials provide a constant and infinitely variable output to both rear
wheels. These unique differentials utilize a series of helical gears which
sense the amount of applied torque and adjust automatically for loss of
traction. The Quaife limited slip design is also free of high wear items
(clutches, ratchets and plates), making them stronger and more maintenance
free than other types of limited slip units. Anyone who has had the pleasure
of driving a vehicle equipped with a Quaife LSD will immediately comment on
its smooth seamless performance, very unlike clutch/plate type LSD's which
exhibit a notchy ratchet like take up through the drive line. The Quaife LSD
that we offer is originally designed as a replacement upgrade for the Sierra
Cosworth and are now supplied with output flanges tapped for either the large
108mm (Cosworth size) or smaller 100mm (XR4 size) C.V. joints.

Clutch Kits We have a very good selection of clutch packages that include
clutch disk, pressure plate, throw out bearing, and clutch alignment tools. Buying one
of our engineered kits will guarantee best quality, performance, fitment (ease of
installation) and price. First option is a new (not rebuilt or re-lined) O.E. quality
replacement clutch kit by Sachs/Valeo. This clutch is best suited for standard or
slightly modified cars being used under normal driving conditions. If your requirements
are beyond the capabilities of the standard clutch we also have some heavy duty clutch
kit options. H.D. clutch kits include pressure plates that have increased clamping force
(from 30 to 50%) and clutch disks with high temperature friction materials applied.
Centerforce H.D. clutch kits have a unique centrifugal pressure plate design with
substantially more clamping force but requires very little pedal pressure over the stock
clutch.
Note: all kits are for standard transmission 1" 23 spline except where noted.

Engine Components
Utilizing a design similar to the earlier German
2000 OHC "Pinto" engine the 2300 "Lima" en-
gine eventually replaced the 2000 OHC in most
North American Ford 4 cylinder vehicles from
1974 on. Built for lower maintenance with the
addition of hydraulic lash
adjusters the 2300
was designed to
operate in a lower
RPM range using
its larger displace-
ment and in-
creased torque to
its best advan-
tage. Perfor-
mance turbo-
charged versions
of the 2300 began
to appear in 1979 in
the Mustang/Capri and continued through the
80's in a more refined and powerfull EFI turbo
version. A reduced bore 2000 displacement
"Ranger" truck engine (from 1983-87) was also
produced. Some late production "Lima" engines
are equipped with hydraulic roller cam and valve
train, and other versions use dual spark plug
cylinder heads. The 2300 is a fairly rugged
engine in its stock form, however some compo-
nents will require up-rating with performance
components if high RPM duty is required. The
"Lima" series turbo and normally aspirated en-
gines respond quite well with a bit of perfor-
mance tuning and though lacking in refinement
do give quite a bit of bang for the buck.
