FAQ

Q1: How do I know if this piston pin is compatible with my 4D56 engine?

A: Compatibility is confirmed by the engine model (4D56 or 4D56T) and the OEM part number. Check the existing pin for the number MD103308. Additionally, verify your engine’s serial number or consult your vehicle’s service manual. This pin is standard for most naturally aspirated and turbocharged 4D56 variants used in the Pajero, L300, and L200.

Q2: What is the correct installation procedure for this piston pin?

A: Installation requires precision. The pin is designed for an interference fit into the connecting rod small end. You will typically need a hydraulic press and appropriate support tools to avoid damaging the piston or rod. Ensure the pin bore in the piston and rod are clean and free of burrs. Always lubricate the pin with clean engine oil before installation. We recommend consulting a professional mechanic or referring to the factory service manual for your specific vehicle.

Q3: Do I need to replace the piston pin bushings or circlips at the same time?

A: Yes, it is highly recommended to replace the connecting rod small-end bushing and the piston pin circlips (retaining rings) whenever you install a new piston pin. These components wear over time and can compromise the fit and longevity of the new pin. Using new circlips is critical for safety, as a failed circlip can cause catastrophic engine damage. We can supply these components upon request.
