PRECAUTIONS
Service Notice or Precautions
PFP:00001
ADS0015Z
●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 exterior 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 outside. 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 moisture, oil, and foreign materials from the application and mounting surfaces.
●Always use shop paper for cleaning the inside of components.
●Avoid using cotton gloves or shop rags to prevent entering of lint.
●During assembly, observe the specified tightening torque, and apply new differential oil, petroleum jelly, or multi-purpose grease as specified for each vehicle, if necessary.
