COATING MATERIALS COATING MATERIALS The recommended coating materials prescribed in Komatsu Utility Shop Manuals are listed below: 00-10 SK818-5 SK820-5 turbo Nomenclature Code Applications Adhesives Bostik 99 Used to apply rubber pads, rubber gaskets and cork plugs. Loctite 406 Used to apply resin, rubber, metallic and non-metallic parts when a fast, strong seal is needed. Loctite 222 Used for low resistance locking of screws, check nuts and adjustment nuts. Loctite 242 To prevent the loosening of bolts, nuts and plugs and the leakage of oil. Used for medium resistance locking of screws and nuts of every type, and for locking keys and bearings.
Loctite 262 Used for high resistant of threaded parts that can be removed with normal tools. Loctite 270 Used for high resistant locking and for sealing threaded parts, bolts and stud bolts. Loctite 542 Used for sealing the union threads for hydraulic tubes. Loctite 573 Used for sealing rather exact plane surfaces when the option of possible future dismantling is required. Loctite 601 Used for high resistant locking of mechanical components that can be removed only after heating Loctite 675 Used to lock cylindrical couplings and for the permanent locking of threaded parts, and also to lock shafts to bearings, gears, pulleys, pins, bushings, etc.
Gasket sealant Loctite 542 Used by itself to seal grease fittings, tapered screw fittings and tapered screw fittings in hydraulic circuits of less than 50 mm in diameter. Loctite 510 Used by itself on mounting flat surface (Clearance between surfaces within 0.2 mm) Loctite 518 Used by itself on mounting flat surface (Clearance between surfaces within 0.5 mm Antifriction compound (Lubricant including Molybdenum disulfide) Litio EP MS2 NLGI 2 Applied to bearings and taper shaft to facilitate press-fitting and to prevent sticking, burning or rusting.
Grease (Lithium grease) Litio EP NLGI 2 Applied to bearings, sliding parts and oil seals for lubrication, rust prevention and facilitation of assembling work. Vaseline ----- Used for protecting battery electrode terminals from corrosion
