FAQ

Q1: Is this piston ring set a direct fit for my Kubota S2200 engine?
A: Yes, part number 15221-21050 is designed specifically for the Kubota S2200 diesel engine. It is manufactured to OEM standard size and specifications. However, we recommend checking your engine’s serial number and cylinder wear condition to confirm if a standard size ring or an oversized ring is required for your rebuild.

Q2: What is included in this piston ring set?
A: The set includes all rings required for one piston in the S2200 engine: typically two compression rings (top and second) and one oil control ring assembly. For a full engine rebuild, you will need to purchase four sets (one per cylinder) along with a piston and liner kit if needed.

Q3: How should I install these piston rings?
A: Installation requires careful attention to ring orientation and gap positioning. Always use a ring expander tool to avoid damaging the rings. Ensure the cylinder bore is clean and within service limits. Stagger the ring end gaps (typically 120 degrees apart) and avoid aligning them with the piston pin or thrust faces. For best results, consult your engine’s service manual and lubricate rings with clean engine oil during assembly.
