NOTE:
Use the product "Form-A-Gasket 2" when sealing between plastic material and cast iron or steel.
Application method for Loctite products
1.
Remove all traces of previous sealants and corrosion
• mechanically: wire brush or emery cloth
• chemically: "DECAPLOC 88" (Leave the product to take effect then scrape off and wipe clean).
2.
Degrease the components with dry solvent: preferably use "Super Solvent Sec LOCTITE 706".
3.
Allow the solvents to evaporate
4.
Apply the recommended type of LOCTITE product to the parts:
• For all blind tapped holes, apply a quantity of the product to the last threads at the bottom of the
hole.
• for cylindrical fittings, apply the product on the two mating faces using a clean brush.
• for mating faces, apply a bead to one of the two faces, circling the holes, and then tighten as quickly
as possible.
NOTE:
• Do not use too much of the compound, in order to avoid locking adjacent parts.
• Do not attempt to retighten after 5 minutes of curing, in order to avoid breaking the film of compound.
• If the ambient temperature is less than +10 °C and to ensure quicker setting of Loctite products (except
SILICOMET), use LOCTITE T 747 activator on at least one of the two parts after phase 2. Excess
product outside the joint will not harden (anaerobic products — curing takes place only when there is no
oxygen).
Grease
When grease is used in components in contact with transmission oil, use grease that is miscible with oil to
avoid blocking the hydraulic filters.
