FAQ

Q1: How can I confirm this piston ring fits my engine?

A: Please verify your engine model is a Cummins LT10 and that the existing part number matches 3803961. We recommend checking the ring size (standard vs. oversized) by measuring your cylinder bore. If you are unsure, please contact us with your engine serial number for confirmation.

Q2: What is included in the package? Is this a complete set?

A: This listing is for a single Piston Ring (3803961). For a full engine rebuild, you may need a complete set of rings for all cylinders. Please confirm the quantity required for your specific engine configuration. We can supply individual rings or sets as needed.

Q3: What is the recommended installation procedure?

A: Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is clean and within specification. Carefully install the rings using a ring expander to avoid breakage. Stagger the ring gaps (typically 120 degrees apart) to prevent gas blow-by. Always refer to the Cummins LT10 service manual for torque specifications and gap clearances.
