HOW TO USE THIS MANUAL
SCOPE OF MAINTENANCE, REPAIR
AND SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Note, however,
that for engine and transmission-related component
parts, this manual covers only on-vehicle
inspections, adjustments, and the removal and
installation procedures for major components.
For detailed information concerning the inspection,
checking, adjustment, disassembly and reassembly
of the engine, transmission and major components
after they have been removed from the vehicle,
please refer to separate manuals covering the
engine and the transmission.
ON-VEHICLE SERVICE
“On-vehicle Service” is procedures for performing
inspections and adjustments of particularly
important locations with regard to the construction
and for maintenance and servicing, but other
inspection (for looseness, play, cracking, damage,
etc.) must also be performed.
INSPECTION
Under this title are presented inspection and
checking procedures to be performed by using
special tools and measuring instruments and by
feeling, but, for actual maintenance and servicing
procedures, visual inspections should always be
performed as well.
DEFINITION OF TERMS
STANDARD VALUE
Indicates the value used as the standard for judging
the quality of a part or assembly on inspection
or the value to which the part or assembly is
corrected and adjusted. It is given by tolerance.
LIMIT
Shows the standard for judging the quality of a
part or assembly on inspection and means the
maximum or minimum value within which the part
or assembly must be kept functionally or in strength.
It is a value established outside the range of
standard value.
REFERENCE VALUE
Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be
completed in a shorter time).
CAUTION
Indicates the presentation of information particularly
vital to the worker during the performance of
maintenance and servicing procedures in order to
avoid the possibility of injury to the worker, or
damage to component parts, or a reduction of
component or vehicle function or performance, etc.
INDICATION OF TIGHTENING TORQUE
The tightening torque shown in this manual is a
basic value with a tolerance of ±10% except the
following cases when the upper and lower limits
of tightening torque are given.
(1) The tolerance of the basic value is within ±10%.
(2) Special bolts or the like are in use.
(3) Special tightening methods are used.

GENERAL – Tightening Torque00-22
TIGHTENING TORQUE
Each torque value in the table is a standard value
for tightening under the following conditions.
(1) Bolts, nuts and washers are all made of steel
and plated with zinc.
(2) The threads and bearing surface of bolts and
nuts are all in dry condition.The values in the table are not applicable:
(1) If toothed washers are inserted.
(2) If plastic parts are fastened.
(3) If bolts are tightened to plastic or die-cast
inserted nuts.
(4) If self-tapping screws or self-locking nuts are
used.

NEW TIGHTENING METHOD – BY USE OF BOLTS TO BE TIGHTENED IN
PLASTIC AREA
A new type of bolts, to be tightened in plastic area, is currently used some parts of the engine. The
tightening method for the bolts is different from the conventional one. Be sure to observe the method
described in the text when tightening the bolts.
Service limits are provided for the bolts. Make sure that the service limits described in the text are strictly
observed.

Areas where the bolts are in use:
(1) Cylinder head bolts
(2) Main bearing cap bolts
(3) Connecting rod cap bolts

Tightening method
After tightening the bolts to the specified torque, tighten them another 90° or 180° (twice 90°). The
tightening method varies on different areas. Observe the tightening method described in the text.
