FAQ

Q: What does +0.50mm oversize mean for my Kubota V2403 engine?

A: This indicates the piston is manufactured with a larger diameter than the standard size. It is used when the engine cylinder bore has been machined (honed or bored) to a larger diameter, typically to repair damage or wear. The +0.50mm piston ensures a proper fit and correct compression in the enlarged bore.

Q: Can I install this piston without machining the cylinder block?

A: No. This is an oversize piston and is intended for use only after the cylinder bore has been professionally machined to the corresponding +0.50mm oversize specification. Installing it in a standard bore will result in a seizure or severe engine damage. Always measure your cylinder bore before purchase.

Q: Do I need to replace the piston rings and cylinder liner as well?

A: Yes, it is highly recommended. For a complete and reliable rebuild, you should use a new set of piston rings designed for the +0.50mm piston. If your engine uses a dry or wet liner, the liner should also be replaced or machined to match the new piston size. We offer matching ring sets and other V2403 rebuild components.
