FAQ

Q1: How do I confirm this piston fits my specific Perkins engine?

Please check the engine model plate located on the valve cover or side of the engine block. Look for the model number (e.g., 1104A-44T) and the engine serial number. Cross-reference these with the part numbers 3135M121 or 4115P025. If your engine is a 1103 or 1104 series with a turbocharger (indicated by “T” in the model name), this piston is the correct fit.

Q2: Does this piston come with piston rings and the pin clip?

This product includes the piston and the piston pin. It does not include the piston rings or the retaining circlips. We recommend ordering a separate piston ring set (e.g., U5MK0084 or 3135A012) and new circlips for a complete overhaul.

Q3: What is the recommended installation procedure for this piston?

Always follow the Perkins service manual for your specific engine. General steps include: 1) Ensure the cylinder bore is clean and within specification. 2) Lubricate the piston pin, rings, and cylinder wall with clean engine oil. 3) Use a proper piston ring compressor to install the piston into the bore. 4) Ensure the arrow on the piston crown points towards the front (flywheel end) of the engine. 5) Torque the connecting rod bolts to the manufacturer’s specification.
