FAQ

Q: How can I be sure this piston will fit my Isuzu 8PD1 engine?
A: Please verify your existing piston’s part number. If it matches 1-12111806-0 or 1-12111-806-0, this is the correct direct replacement. Also, confirm that your engine block has a standard bore size of 119mm. This piston is specifically designed for the 8PD1, 10PD1, and 12PD1 models.

Q: What is the advantage of the “Alfin Inserted” feature?
A: The Alfin insert is a steel ring bonded into the aluminum piston at the top ring groove. This reinforcement provides superior resistance to high-temperature wear and micro-welding, which is common in turbocharged diesel engines. It significantly extends the life of the piston and ring assembly under heavy load conditions.

Q: Do I need to replace the piston pin or rings when installing this piston?
A: Yes, it is highly recommended to install a new piston pin and a complete set of piston rings when replacing the piston. This ensures optimal sealing and prevents premature wear. The pin size for this piston is 43mm * 80mm. Always follow the engine manufacturer’s service manual for proper installation procedures and torque specifications.
