Description
When your Kubota engine starts burning oil or losing compression, it’s time to think about a rebuild. This oversized piston and ring kit gives you a solid foundation to get your engine back to like-new performance. The .020 oversize pistons work perfectly with cylinders that have been bored out to remove wear and scoring—a common step in any quality engine rebuild.
What You’re Getting
- Complete piston assembly with rings already fitted and ready to install
- Includes wrist pin bushing for proper pin-to-rod connection
- Precision-machined to .020 oversize specifications for rebuilt cylinders
- Quality construction that meets or exceeds original equipment standards
- Everything you need in one kit—no hunting for separate components
Built for Real Farm Work
This kit is designed for Kubota diesel engines that power everything from compact utility tractors to larger agricultural machines. Whether you’re rebuilding an engine in a loader tractor that’s seen years of hard use or refreshing a field tractor that’s lost its pep, these oversized pistons restore the tight tolerances your engine needs to run strong.
Made to Last
Engine rebuilds aren’t something you want to do twice, so this kit uses quality materials that can handle the heat, pressure, and constant duty cycle of farm work. The rings are designed to seal properly from day one and maintain that seal through thousands of hours of operation.
Installation Notes
This is a .020 oversized kit, so your cylinders will need to be bored and honed to match. Most machine shops can handle this work, and it’s worth doing right the first time. The wrist pin bushing ensures proper clearances between the pin and connecting rod—don’t skip this step even if the old bushing looks okay.
