DISASSEMBLY
I
ASSEMBLY PROCEDURES
DISASSEMBLY
• Before disassembly and cleaning, carefully check for
defects which cannot be found after disassembly and
cleaning.
• Drain water, fuel and oil before disassembly.
• Clean or wash the engine exterior.
•
Do
not remove or disassemble the parts that require no
disassembly.
• Perform disassembly in a proper order using proper tools.
Keep disassembled parts in order. Apply oil when
necessary. Take special care to keep the fuel system parts
from intrusion of dust and dirt.
• Parts
must
be
restored to their respective components from
which they were removed at disassembly. This means that
all
parts
must
be
set
aside separately in groups, each marked for
its
componen~
so
that
the
sarne combination or set can be
reproduced at assembly.
• Pay attention to marks on assemblies, components and
parts
for their positions or directions. Put on marks, if
necessary, to aid assembly ..
• Carefully check
each
part or component for any sign of
faulty condition during removal or cleaning. The part will
tell you how it acted or what was abnormal about it more
accwately during removal or cleaning.
The
parts
assembled with the silicone can be easily
disassembled without use of a special method. In some case,
however, the sealant between the joined surfaces may have
to be broken by lightly striking with a mallet or similar tool.
A ftat and thin gasket scraper may be lightly hammered'
in between the joined surfaces. In this case, care must be
taken to prevent damage to the joined surfaces. For removal
of the oil pan, use a special "oil pan remover".
ASSEMBLY
• Wash all parts, except for oil seals, O-rings, rubber sheets,
etc., with cleaning solvent and dry them with pressure air.
• Always use tools that are in good condition and be sure
you understand how to use them before performing any
job.
• Use only good quality lubricants. Be sure to apply a coat
of oil,
grease
or sealant to parts as specified ..
• Be sure to use a torque wrench to tighten parts for whieh
torques are specified.
• When the engine is assembled, new gaskets and O-rings
must be installed.
Surface Preparation
Thoroughly removes all substances deposited on the gasket
application surfaces using a gasket scraper or wire brush.
Check to ensure that the surfaces to which the silicone gasket
is to be applied is ftat. make sure that there are no oils,
greases and foreign substances deposited on the application
surfaces. Do not forget to remove the old sealant that
remains in the bolt holes.
GASKET INFORMATION
The engine has several areas where form-in-place
RTV
silicone gaskets are used such as LOCTITE 598 or GE
RTV 100.
To ensure that the gasket fully serves its purpose,
it is necessary to observe some precaution when applying the
gasket. Bead size, continuity and location are very important.
Too thin a bead could cause leaks and too thick a bead could
be squeezed out of location causing blOCking or narrowing of
the fluid feed lines. To eliminate the possibility of leaks from
a joint, it is necessary to apply the gasket evenly without a
break while observing the correct bead size.
The gasket material used in the engine is a room temperature
vulcanization
(RTV)
type and is supplied in a
140z (400
gram)
applicator/tube. The
RTV
hardens as it reacts with the
moisture in the atmospheric air and can be used for sealing
both engine oil and coolant assemblies.
