FORM-IN-PLACE GASKET (FIPG)
The engine has several areas where the
form-in-place gasket (FIPG) is in use. To ensure that
the gasket fully serves its purpose, it is necessary to
observe some precautions when applying the gas
-
ket.
Bead size, continuity and location are of paramount
importance. Too thin a bead could cause leaks. Too
thick a bead, on the other had, could be squeezed
out of location, causing blocking or narrowing of the
fluid feed line. To eliminate the possibility of leaks
from a joint, therefore, it is absolutely necessary to
apply the gasket evenly without a break, while
observing the correct bead size.
Since the FIPG used in the engine is hardens as it
reacts with the moisture in the atmospheric air, it is
normally used in the metallic flange areas.
Disassembly
The parts assembled with the FIPG can be easily
disassembled without use of a special method. In
some cases, however, the sealant between the
joined surfaces may have to be broken by lightly
striking a part with a mallet or similar tool. A flat and
thin gasket scraper may be lightly hammered in
between the joined surfaces. In this case, however,
care must be taken to prevent damage to the joined
surfaces.
Surface Preparation
Thoroughly remove all substances deposited on the
gasket application surfaces, using a gasket scraper
or wire brush. Check to ensure that the surfaces to
which the FIPG is to be applied is flat. Make sure that
there are no oils, greases and foreign substances
deposited on the application surfaces. Do not forget
to remove the old gasket remaining in the bolt holes.
Application
Apply FIPG as a bead of the specified size without
breaks. Be sure to encircle the bolt hole circumfer
-
ence with a completely continuous bead. The FIPG
can be wiped away unless it is hardened. While the
FIPG is still moist (in less than 3 minutes), mount the
parts in position. When the parts are mounted, make
sure that the gasket is applied to the required area
only. Never apply oil or water on the FIPG nor start
the engine until a sufficient time (approx. 2 hours)
has passed. The FIPG application procedure may
vary on different areas. Observe the procedure
described in the text when applying the FIPG.
