FORM-IN-PLACE GASKETS
There are numerous places where form-in-place gaskets are used on the engine. Care must be
when applying form-in-place gaskets to assure obtaining the desired results. size, continuity, ‘and
location are of great importance. Too thin a bead can result in leakage
too much can result’ in
spill-over which can break off and obstruct fluid f eed lines.
A continuous bead of the proper width
essential to obtain a leak-free joint.
GASKET DISASSEMBLY
Parts assembled with form-in-place gaskets may be d isassembled without unusual effort’
it may be necessary to lightly tap the part with a mallet or other suitable tool to break the seal between
the mating surfaces.A flat gasket scraper may also be lightly tapped in to the joint but care be
taken not to damage the mating surfaces.
SURFACE PREPARATION
Scrape clean or wire brush all gasketsurfaces removing all loose material. Inspect
assure gasket rails are flat.
Flatten rails with a hammer on a flat plate if
must be free of oil and dirt. Make sure old gasket material is removed from blind
FORM-IN-PLACE GASKET APPLICATION
Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gaskets.
Gasket material should be applied sparingly 1 mm

surface, Be certain the material surrounds each mou nting hole.
Excess material can easily be
‘off. Components should be torqued in place within 15 minutes. The use of a locating dowel is recommen ded
during assembly, to prevent smearing the material off location.

ENGINE LUBRICATION General Information/Lubricants
G E N E R A L I N F O R M A T I O N
The lubrication method is a fully force-fed, full-f low
filtration type.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis .
In addition, used engine oil
potentially
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
l Wear protective clothing, including impervious
gloves where practicable.
l Avoid contaminating clothes, particularly
underpants, with oil.
l Do not put oily rags in packets, the use of
overalls without pockets will avoid this.
l Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
LUBRICANTS
harmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must
provided.
Where there is a risk of eye contact, eye protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
Obtain First Aid treatment immediately for open
cuts and wounds.
Wash regularly with soap and water to ensure
all oil is removed, especially before
cleansers and nail brushes will help). After
cleaning, the application of
containing lanolin to replace the natural
oil is advised.. .
Do not use gasoline, kerosine, diesel fuel,
oil, thinners or solvents for cleaning skin.
Use barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
If skin disorders develop, obtain medical advice
without delay.

REAR AXLE Special Tools
The rear axle consists of a knuckle, rear hub, unit
bearing and axle shaft. The unit bearing is
fitted to the rear axle shaft and bolted to the knuckle.
Also, the unit bearing utilizes the same type of
double row angular contact ball bearing as does
the front axle.
On, ABS, a ABS rotor
for detecting the speed is located on the
and sensor is located on
the knuckle.
