FAQ
Q1: How do I confirm this piston fits my Mitsubishi K3D or K4D engine? A1: Verify your engine model code (K3D or K4D) stamped on the engine block. Additionally, check the existing piston part number; if it matches MM406610 or an equivalent OEM number, this assembly is the correct replacement. If you are unsure, please contact us with your engine serial number.
Q2: Does the assembly include piston rings? A2: This product specifically includes the piston and the piston pin only. Piston rings are sold separately. We recommend replacing rings simultaneously with the piston for optimal sealing and performance. Please check our store for compatible ring sets.
Q3: What is the recommended installation procedure? A3: Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is clean and within service limits. Lubricate the piston and pin before assembly. Always torque connecting rod bolts to the manufacturer’s specifications. For detailed instructions, refer to the Mitsubishi K3D/K4D service manual.
