FAQ

1. How do I confirm if this piston fits my engine?

First, verify your engine model is a Mitsubishi 6M61. Then, check the part number on your old piston. If it matches ME131937, this is the correct replacement. For oversize pistons (e.g., 0.50mm), please check the marking on your old piston or cylinder block.

2. What is the recommended installation procedure?

We recommend professional installation by a qualified diesel mechanic. Key steps include: cleaning the cylinder bore, lubricating the piston and rings, using a proper ring compressor, and following the manufacturer’s torque specifications for the connecting rod bolts.

3. How should I store the piston if not used immediately?

Store the piston in a clean, dry environment. Keep it in its original packaging to prevent scratches or contamination. Avoid exposure to high humidity or corrosive chemicals. For long-term storage, apply a light coat of rust-preventive oil to the piston surface.
