High Flash-point Solvent
A high flash-point solvent is recommended to
reduce fire danger. Always follow manufacturer
and container directions regarding the use of any
solvent.
(7 )
Gasket, O-ring
Do not reuse a gasket or O-ring once it has been
in service. The mating surfaces around the gasket
should be free of foreign matter and perfectly
smooth to avoid oil or compression leaks.
(8 ) Press
A part installed using a press or driver, such as a
wheel bearing, should first be coated with oil on its
outer or inner circumference so that it will go into
place smoothly.
(9 ) Ball Bearing
When installing a ball bearing, the bearing race
which is affected by friction should be pushed by
a suitable driver. This prevents severe stress on
the balls and races, and prevents races and balls
from being dented. Press a ball bearing until it
stops at the stop in the hole or on the shaft.
(l0 )
Oil Seal and Grease Seal
Replace any oil or grease seals that were removed
with new ones, as removal generally damages
seals.
When pressing in a seal which has manufacturer’s
marks, press it in with the marks facing out. Seals
should be pressed into place using a suitable
driver, which contacts evenly with the side of seal,
until the face of the seal is even with the end of the
hole.
(11 ) Seal Guide
A seal guide is required for certain oil or grease
seals during installation to avoid damage to the
seal lips. Before a shaft passes through a seal,
apply a little oil, preferably high temperature grease
on the lips to reduce rubber to metal friction.
(12 ) Circlip, Retaining Ring
Replace any circlips and retaining rings that were
removed with new ones, as removal weakens and
deforms them. When installing circlips and
retaining rings, take care to compress or expand
them only enough to install them and no more.
(13 ) Cotter Pin
Replace any cotter pins that were removed with
new ones, as removal deforms and breaks them.
GENERAL PRECAUTIONS (Dismantling / assembly)
Before Servicing
Before starting to service a vehicle, careful reading of the
applicable section is recommended to eliminate
unnecessary work. Photographs, diagrams, notes,
cautions, warnings, and detailed descriptions have been
included wherever necessary. Nevertheless, even a
detailed account has limitations, a certain amount of
basic knowledge is also required for successful work.
Especially note the following:
(1 )
Dirt
Before removal and disassembly, clean the
vehicle. Any dirt entering the engine or other parts
will work as an abrasive and shorten the life of the
vehicle. For the same reason, before installing a
new part, clean off any dust or metal filings.
(2 )
Tightening Sequence
Generally, when installing a part with several
bolts, nuts, or screws, they should all be started in
their holes and tightened to a snug fit. Then
tighten them evenly in a cross pattern. This is to
avoid distortion of the part and/or causing gas or
oil leakage. Conversely when loosening the bolts,
nuts, or screws, first loosen all of them by about a
quarter of turn and then remove them.
Where there is a tightening sequence indication in
this Service Manual, the bolts, nuts, or screws
must be tightened in the order and method
indicated.
(3 )
Torque
The torque values given in this Service Manual
should always be adhered to. Either too little or too
much torque may lead to serious damage. Use a
good quality, reliable torque wrench.
(4 )
Force
Common sense should dictate how much force is
necessary in assembly and disassembly. If a part
seems especially difficult to remove or install, stop
and examine what may be causing the problem.
Whenever tapping is necessary, tap lightly using
a wooden or plastic faced mallet. Use an impact
driver for screws (particularly for the removal of
screws held by a locking agent) in order to avoid
damaging the screw heads.
(5 )
Edges
Watch for sharp edges, especially during major
engine disassembly and assembly. Protect your
hands with gloves or a piece of thick cloth when
lifting the engine or turning it over.
