STRUCTIONS ON SERVICE OPERATIONS
1.
Make sure that only the specified bolts and nuts are used. Also, where specified, be sure to employ a
torque wrench to tighten bolts or nuts to specifications.
2.
When tightening or slackening bolts, be sure to progressively tighten or slacken them over several
stages, slightly at a time. This caution must be observed to prevent the tightened parts from being
distorted or damaged.
3.
Use only genuine parts for every replacement operation.
4.
For increased working efficiency and improved accuracy, utilize SSTs (Special Service Tools)
effectively.
5.
When both front and rear sections of the vehicle or only the rear section thereof is jacked up, make
certain to place chocks at the wheels correctly in order to assure safe operations.
6.
When the vehicle is jacked up, make sure to support the vehicle with safety stands positioned at the
specified jacking points.
7.
Before any repair work is made on the electrical system or the engine is removed or installed, first be
sure to disconnect the negative
(-)
terminal of the battery.
8.
Disassembly
(1)
When complicated part are disassembled, put stamped marks or mate marks on suitable
non-functional sections of the parts in order that the said parts may be easily assembled in the
correct original positions.
(2)
Replacements of the cylinder block or crankshaft, etc. should be carried out after the engine
assembly has been removed from the vehicle.
9.
Checks to be performed during disassembly
Each time a part is removed, check conditions under which the part has been assembled. Also, check
to see if the part exhibits any evidence of distortion, breakage, wear or scores, etc.
10.
Arrangement of disassembled parts
Put disassembled parts in a good order. Moreover, divide disassembled parts into two groups: those
parts to be replaced and those parts which can be reused.
11.
Washing disassembled parts
As for those parts which can be reused, thoroughly clean or wash them. (except grease sealed
bearing)
12.
Inspection
Those parts which are to be reused must
becarefully inspected or measured, as required.
13.
Those operations specified under "lnspection" are performed, in principle, in combination with the
checks and repairs.
It is, therefore, necessary to replace any part which does not conform to the
;pecifications. However, in cases where otherwise specified in the main text, be sure to follow the given
instructions.
14.
Assembly of parts
Those satisfactory parts only should be assembled in accordance with the prescribed standards
(e.g.
specified adjustment values, tightening torque and so forth).
Furthermore, seal packing or grease should be applied, as required.
Furthermore, in respect to packings, gaskets, oil seals and similar items, be certain to install new parts.
15.
Adjustments and checking of service operations
Service operations must be carried out correctly by means of gauges or testers, if the use of these
instruments is required.
16.
Never smoke during the service operation. Also, be sure not to allow any fire to be brought near the
working bay.
17.
Under no circumstances should your hand touch with the front side and back sides, the installation
surfaces of each bearing insert. Also, be very careful not to
scratch the surfaces. Do not wipe
off
the
bearing surfaces with a cloth. Be certain to blow off them, using compressed air:
Protect your eyes with safety glasses during this cleaning.
