FAQ

Q1: How do I confirm this piston fits my specific Cummins QSB6.7 engine?
A: Check your engine’s data plate or service manual for the engine serial number and existing piston part number. The OEM numbers 5529330 and 0205519 are direct references for standard-size QSB6.7 pistons. For engines with oversize or undersize bores, please verify the piston diameter and ring specifications before ordering.

Q2: Does this piston come with rings and a wrist pin?
A: This is a complete piston assembly that typically includes the piston body, piston rings, and wrist pin as per OEM configuration. However, we recommend confirming the exact contents with our sales team before placing an order to ensure you receive the correct configuration for your engine build.

Q3: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: (1) Clean the cylinder bore thoroughly, (2) Lubricate the piston rings and pin, (3) Use a ring compressor to install the piston into the bore, (4) Ensure proper ring gap orientation per Cummins service guidelines, and (5) Torque connecting rod bolts to manufacturer specifications. Always consult the Cummins QSB6.7 service manual for detailed procedures.
