Disassembling the Engine and Components
Features and Application
Non-drying liquid gasket; solvent-less type, easy to remove,
superior in seawater resistance, applicable to the various mating
surfaces.
Non-drying liquid gasket; easy to apply, superior in water
resistance and oil resistance, especially superior in gasoline
resistance.
Drying film, low viscosity and forming of thin film, appropriate for
the mating surface of precision parts.
Semi-drying visco-elastic material, applicable to a non-flat
surface having many indentations and protrusions, superior in
heat resistance, water resistance and oil resistance.
Solvent-less type silicone-based sealant, applicable to high
temperature areas (-50° to 250°C (-58° to 482°F)).
Silicone-based, non-fluid type, thick application possible.
Prevention of loose bolts, gas leakage and corrosion. Torque
required to loosen bolt: 10 to 20% larger than tightening torque.
Excellent adhesive strength locks the bolt semi-permanently.
Sealing material for the threaded parts of various pipes.
Ambient temperature range:
-150° to 200°C (-238° to 392°F)
For assembly of engine cylinders, pistons, metals shafts, etc.
Spray type facilitates application work.
Prevention of seizure of threaded parts at high temperature.
Applicable to the intake / exhaust valves (stem, guide, face)
• The scale solvent removes scale in a short time (1 to 10
hours).
• Prepare the coolant (seawater is possible) in an amount that
is about 10 times the weight of the solvent. Mix the solvent
with coolant.
• Dipping the disassembled part into solvent removes scale. To
shorten the removal time, stir the remover mixture.
• If the cleaning performance drops, replace the remover
mixture with a new remover mixture.
• Neutralize the used mixture and dispose of it. To judge the
cleaning performance of the mixture, put pH test paper into
the mixture. If the test paper turns red, the remover mixture is
still effective.
Add antirust to the freshwater system at the cold area to operate
the engine.
• The cleaning agent removes substances, such as carbon,
adhering to disassembled parts.
• If a cleaning machine is used, prepare 4 to 6% mixture of 60°
to 80° to ensure more effective cleaning.
