FAQ

Q1: Is this piston ring set a direct fit for my Yanmar 3TNV72 engine in a mini excavator?
A: Yes, the 119517-22500 set is designed as a direct OEM replacement for the 3TNM72, 3TNE72, and 3TNV72 engines. Ensure your engine block bore is 72mm (standard) and not previously overbored. For overbored engines, please contact us for oversize options.

Q2: What is the recommended installation procedure for these rings?
A: Use a ring expander tool to avoid damaging the rings. Stagger the ring gaps 120 degrees apart (top, second, oil ring) around the piston. Lubricate with clean engine oil before installation. Torque cylinder head bolts to Yanmar factory specifications (typically 40-50 ft-lbs for 3TNE72 series).

Q3: How can I verify the part number before purchasing?
A: Check your engine’s data plate or service manual for the original Yanmar part number. The OEM number YM119517-22500 should be listed. You can also measure the cylinder bore diameter; it must be 72mm for standard rings. If unsure, send us a photo of your old ring set or engine model tag for cross-verification.
