CAUTION:
• Check for the correct installation status prior to removal or disassembly. If matching marks are
required, be certain they do not interfere with the function of the parts when applied.
• Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
• Before disassembly, using steam or white gasoline, completely remove sand and mud from the exte-
rior of the unit, preventing them from entering into the unit during disassembly or assembly.
• Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace
them with a new ones if necessary.
• Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-
side. If tightening sequence is specified, observe it.
• Clean and flush the parts sufficiently and blow-dry them.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mounting surface; then remove any mois-
ture, oil, and foreign materials from the application and mounting surfaces.
• Always use shop paper for cleaning the inside of components.
• Never use cotton gloves or shop rags to prevent entering of lint.
• During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or
multi-purpose grease as specified for each vehicle, if necessary.
