Inspection After Removal
WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.
- When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
- Do not exceed 207 kPa (2.111 kg/cm 2 , 30 psi).
- Wear appropriate eye protection and protective clothing including gloves.
NOTE:
Be certain that debris does not fall into the front gear cover.
- Use solvent to clean the oil and seal residue from the crankshaft surface.
- Clean the surface between the front oil seal and front gear cover.
- Clean the crankshaft nose and front gear cover with solvent.
- Clean the front gear cover seal bore of any seal or oil residue.
- Inspect the front gear cover seal bore for nicks or burrs.
- Do not use an abrasive pad containing metal on the crankshaft.
- Dry with compressed air.
- Inspect the seal contact area on the vibration damper (1) for a wear groove (A). If the groove is deeper than 0.25 mm (0.010 in), the vibration damper must be replaced.CAUTION: To avoid possible seal damage, the seal lip and the sealing surface on the damper must be free from all oil residue to prevent seal leaks.
