GENERAL INFORMATION

Oil Seals
General
Always renew oil seals which have been removed
from their working location (whether as an individual
component or as part of an assembly). NEVER use
a seal which has been improperly stored or handled,
such as hung on a hook or nail.
lCarefully examine seal before fitting to ensure
that it is clean and undamaged.
lEnsure the surface on which the new seal is to
run is free of burrs or scratches. Renew the
component if the original sealing surface cannot
be completely restored.
lProtect the seal from any surface which it has to
pass when being fitted. Use a protective sleeve
or tape to cover the relevant surface.
lLubricate the sealing lips with a recommended
lubricant before use to prevent damage during
initial use. On dual lipped seals, smear the area
between the lips with grease.
lIf a seal spring is provided, ensure that it is fitted
correctly. Place lip of seal towards fluid to be
sealed and slide into position on shaft. Use
fitting sleeve where possible to protect sealing
lip from damage by sharp corners, threads or
splines. If a fitting sleeve is not available, use
plastic tube or tape to prevent damage to the
sealing lip.
lGrease outside diameter of seal, place square
to housing recess and press into position using
great care, and if possible a 'bell piece' to
ensure that seal is not tilted. In some cases it
may be preferable to fit seal to housing before
fitting to shaft. Never let weight of unsupported
shaft rest in seal.lUse the recommended service tool to fit an oil
seal. If the correct service tool is not available,
use a suitable tube approximately 0.4 mm
(0.015 in.) smaller than the outside diameter of
the seal. Use a hammer VERY GENTLY on drift
if a suitable press is not available.
lPress or drift the seal in to the depth of its
housing with the sealing lip facing the lubricant
to be retained if the housing is shouldered, or
flush with the face of the housing where no
shoulder is provided. Ensure that the seal does
not enter the housing in a tilted position.

GENERAL INFORMATION
03-15
Hose clips
Markings (4) are usually provided on the hose to
indicate the correct clip position. If no markings are
provided, position the clip directly behind the
retaining lip at the end of the stub as shown. Worm
drive clips should be oriented with the crimped side
of the drive housing (5) facing towards the end of the
hose, or the hose may become pinched between the
clip and the stub pipe retaining lip. Worm drive clips
should be tightened to 3 Nm (2 lbf.ft) unless
otherwise stated. Ensure that hose clips do not foul
adjacent components.
Heat protection
Always ensure that heatshields and protective
sheathing are in good condition. Replace if damage
is evident. Particular care must be taken when
routing hoses close to hot engine components, such
as the exhaust manifold and the Exhaust Gas
Recirculation (EGR) pipe. Hoses will relax and
deflect slightly when hot; ensure this movement is
taken into account when routing and securing hoses.
Rolling Road Testing
General
IMPORTANT: Use a four wheel rolling road for
brake testing if possible.
WARNING: Do not attempt to test ABS function
on a rolling road.
Four wheel rolling road
Provided that front and rear rollers are rotating at
identical speeds and that normal workshop safety
standards are applied, there is no speed restriction
during testing except any that may apply to the tyres.
Before testing a vehicle with anti-lock brakes on a
four wheel rolling road, disconnect the ABS
modulator. The ABS function will not work, the ABS
warning light will illuminate. Normal braking will be
available.
Two wheel rolling road
Up to 03MY
ABS will not function on a two wheel rolling road. The
ABS light will illuminate during testing. Normal
braking will be available.
If brake testing on a two wheel rolling road is
necessary, the following precautions should be
taken:
lPropeller shaft to the rear axle is removed.
lNeutral selected in gearbox.
When checking brakes, run engine at idle speed to
maintain servo vacuum.
From 03MY
The differential lock must be engaged for two wheel
rolling road testing. It will also be necessary to
disconnect the propeller shaft from the transfer box
output shaft driving the axle whose wheels are NOT
on the rolling road. Additionally, the ETC system
must be deactivated by either removing the 10 amp
fuse (Number 28, labelled ABS in the main fuse box)
or disconnecting the ABS modulator pump. This
must be done with the ignition OFF ; a fault in the
ABS system may still be recorded.
WARNING; VEHICLES NOT FITTED WITH A
DIFFERENTIAL LOCK MUST NOT BE TESTED
ON A ROLLING ROAD WHERE THE ROLLERS
ARE DRIVEN BY THE VEHICLE.
