FORM-IN-PLACE GASKET (FIPG)
FIPG is used for several members of this transmission. With this gasket, caution is required to the application
amount, application procedure and state of the application surface so that the performance is sufficiently
attained.
If sufficient gasket is not applied, leaks could occur, and if too much is applied, the gasket could protrude
and plug or restrict the oil flow passage. Thus, to prevent leaks from the joined sections, it is absolutely
necessary to evenly apply the correct amount.
DISASSEMBLY
The parts assembled with FIPG can be easily disassembled without special means. However, in some
cases, the sealant on the contact surfaces must be broken by lightly tapping with a wood hammer or
similar tool.
Washing the gasket surface
Completely remove all matters adhered on the contact surfaces with a gasket scraper. Confirm that the
FIPG application surface is smooth. There must be no grease or foreign matter on the contact surfaces.
Always remove the old FIPG that has entered the mounting holes and screw holes.
APPLICATION PROCEDURES
Apply an even coat of FIPG within the predetermined radius (1.5 ± 0.3 mm). Completely cover the areas
around the mounting holds. The FIPG can be wiped off if it has not hardened. Install at the set position
while the FIPG is still wet (within 10 minutes). When installing, make sure that the FIPG does not get
on areas other than the required areas. After installing, do not subject the application areas to oil or
water or start operation until the FIPG has sufficiently hardened (approx. one hour).
The FIPG application procedures differ according to the member, so follow the procedures given in this
manual and apply the FIPG.
