q   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.
q   Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
q   Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
    the unit, preventing them from entering into the unit during disassembly or assembly.
q   Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
    with a new ones if necessary.
q   Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
q   In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
    tightening sequence is specified, observe it.
q   Clean and flush the parts sufficiently and blow-dry them.
q   Be careful not to damage sliding surfaces and mating surfaces.
q   When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
    and foreign materials from the application and mounting surfaces.
q   Always use shop paper for cleaning the inside of components.
q   Avoid using cotton gloves or shop rags to prevent entering of lint.
q   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.
