PRECAUTIONS
PRECAUTIONS PFP:00001
Service Notice or Precautions ADS00193
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.
