- Check for the correct installation before removal or disassembly. If matching marks are required, make sure that they do not interfere with the function of the parts they are applied to.
- 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.
- Replace lock pins, oil seals and bearings with new ones every time they are removed.
- Use Genuine NISSAN parts for replacement.
- In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, observe it. Observe a tightening sequence if specified.
- Clean and flush the parts sufficiently and dry them with compressed air.
- Be careful not to damage sliding surfaces and mating surfaces.
- Always use paper type waste for cleaning the inside of components.
- To prevent the entry of lint, do not use cotton gloves or a shop cloth.
- During assembly, observe the specified torque and apply new NISSAN differential oil or multi-purpose grease, as specified for each vehicle.
- Never use gasket fluid because it may dissolve in the gear oil.
- 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.
- When the transmission oil temperature exceeds 284°F (140°C) while driving: Change both transmission oil and differential oil immediately after stopping. Differential oil temperature usually increase concurrently.
NOTE:
Because there is not enough space for service, the front oil seal cannot be replaced on the vehicle.
