FAQ

Q: How do I confirm this cam bush fits my specific engine?
A: Please verify the OEM part number stamped on your existing cam bush or listed in your engine’s service manual. The critical numbers to match are 34307-12700 or 34307-02700. This part is specifically engineered for the Mitsubishi S6S diesel engine. If your engine model and part number match, this component is the correct replacement.

Q: What is the recommended installation procedure for this cam bush?
A: Installation should be performed by a qualified diesel mechanic. The cam bush must be pressed into the cylinder head bore using a proper drift tool to avoid deformation. It is critical to align the oil hole in the bush with the oil gallery in the cylinder head to ensure proper lubrication. After installation, the inner diameter should be checked and may require honing to achieve the correct clearance with the camshaft journal (typically 0.03-0.07mm). Always refer to the Mitsubishi S6S workshop manual for exact torque and clearance specifications.

Q: Can this part be used for an engine rebuild or only for a specific repair?
A: This cam bush is suitable for both full engine overhauls and targeted valve train repairs. During a major rebuild, replacing all cam bushes is recommended to ensure consistent oil clearance and camshaft support. If you are repairing a specific issue like low oil pressure or a knocking noise from the camshaft area, replacing the worn bush is a standard and effective solution. We recommend replacing the camshaft seals and checking the camshaft journals for wear at the same time.
