FAQ
Q: Is this piston compatible with my Kubota V1902-B engine? A: Yes, part numbers 15521-21110, 19274-21110, and 19439-21110 are standard for the Kubota V1902 engine series, including the V1902-B variant. We recommend checking your old piston’s marking for confirmation.
Q: Do I need to replace piston rings at the same time? A: Yes, it is highly recommended to install new piston rings with new pistons to ensure proper compression and oil control. The ring grooves on this piston are designed for standard Kubota rings.
