GENERAL FITTING INSTRUCTIONS 10711
-=
>.
6. Grease 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.

7. If correct service tool is not available, use a suitable
drift approximately 0,4
mm (0.015 in) smaller than
outside diameter
of seal. Use a hammer VERY
GENTLY on drift if a press is not suitable.
8. Press or drift seal in to depth of housing if housing
is shouldered, or flush with face of housing where
no shoulder is provided. Ensure that the seal does
not enter the housing in a tilted position.
NOTE: Most cases of failure or leakage of oil seals
are due to careless fitting, and resulting damage to
both seals and sealing surfaces. Care in fitting
is
essential if good results are to be obtained.
JOINTS AND JOINT FACES
1. Always use correct gaskets where they are
spccificd.
2. Use jointing compound only when recommended.
Otherwise
fit joints dry.
3. When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent
it from entering oilways, pipes or blind
tapped holes.
4. Remove all traces of old jointing materials prior to
reassembly.
Do not use a tool which could damage
joint faces.
5. Inspect joint faces for scratches or burrs and
remove with a fine
file or oil stone; do not allow
swarf or dirt to enter tapped holes or enclosed
parts.
6. Blow out any pipes, channels or crevices with
compressed air,
renewing any 0
- rings or seals
displaced by air blast.
FLEXIBLE HYDRAULIC PIPES, HOSES
1. Before removing any brake or power steering hose,
clean end fittings and area surrounding them as
thoroughly as possible.
2. Obtain appropriate blanking caps before detaching
hose end fittings,
so that ports can be immediately
covered to exclude dirt.
3. Clean hose externally and blow through with
airline. Examine carefully for cracks, separation of
plies, security
of end fittings and external damage.
Reject any hose found
faulty.
4. When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is
not twisted
before or during tightening of union nuts.
5. Containers for hydraulic fluid must be kept
absolutely clean.
6. Do not store hydraulic fluid in an unsealed
container. It will absorb water, and fluid
in this
condition would be dangerous to use due to a
lowering of its boiling point.
7. Do not allow hydraulic fluid to be contaminated
with mineral oil, or use a container which has
previously contained mineral oil.
8. Do not re - use fluid bled from system.
9. Always use clean brake fluid to clean hydraulic
components.
10. Fit a blanking cap to a hydraulic union and a plug
to its socket after removal to prevent ingress
of
dirt.
11. Absolute cleanliness must be observed with
hydraulic components at all times.
12. After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to the
brakes (engine running) and operates the steering.
METRIC BOLT IDENTIFICATION
1. An IS0 metric bolt or screw, made of steel and
larger than
6 mm in diameter can be identified by
either of the symbols
IS0 M or M embossed or
indented
on top of the head.
2. In addition to marks to identify the manufacture,
the head is also marked with symbols to indicate
the strength grade
e.g. 8.8, 10.9, 12.9 or 14.9,
where the first figure gives the minimum tensile
strength
of the bolt material in tens of kg/sq mm.
3. Zinc plated IS0 metric bolts and nuts are chromate
passivated, a greenish
- khaki to gold - bronze colour.
