Description
When you’re rebuilding a diesel engine, every part matters – but none more than the pistons. This 4.4″ bore piston is an exact .030″ oversize replacement that’ll bring your worn engine back to life. Whether you’re dealing with blow-by, oil burning, or just rebuilding for peace of mind, this oversize piston works with a freshly-bored cylinder to give you that tight compression your diesel needs to run strong again.
What You’re Getting
- Precision-machined 4.4″ bore diameter for exact cylinder fit after boring
- 030″ oversize specification restores proper compression in worn engines
- Quality construction that handles the heat and pressure of diesel operation
- Direct replacement that works with standard rings and connecting rods
Built for Diesel Work
This piston fits a wide range of Ford and New Holland diesel tractors that have served farms reliably for decades. These are the tractors that handle everything from daily chores around the farmstead to heavy field work during planting and harvest. When these engines start showing their age with reduced power or excessive oil consumption, a proper rebuild with oversized pistons brings them back to factory specifications.
Made to Last
Diesel pistons take tremendous punishment from high compression ratios and constant heat cycling. This piston is built to handle those conditions with materials and design that match the durability expectations of farm equipment. The precision machining ensures proper ring seal and heat transfer, while the robust construction withstands the stress of hard-working diesel engines.
Installation Notes
This is part of an engine rebuild, so you’ll need proper machine shop work to bore the cylinders to the correct oversize. Make sure your machine shop maintains proper bore finish and cylinder alignment. Use new rings, pins, and gaskets during assembly – mixing old parts with new pistons is false economy that leads to premature failure.
