Description
When you’re tearing down an engine for rebuild and find worn cylinders that need a light machine job, this .020″ oversize piston is exactly what you’re looking for. Instead of boring all the way out to .030″ or .040″, you can often save money and keep more metal in your block with just a twenty-thousandths cleanup. It’s the kind of rebuild decision that makes sense when you’re trying to get the most life out of a good engine block.
What You’re Getting
- Precision-manufactured .020″ oversize piston that restores proper compression and oil control
- 4.4″ diameter designed to work with freshly bored cylinders for optimal clearances
- Quality TISCO construction that meets OEM specifications at a fair price
- Direct replacement for worn pistons without requiring major machine work
Built for Real Farm Work
This piston fits Ford and New Holland diesel engines found in utility and row-crop tractors that handle everything from hay operations to cultivation work. These are the reliable engines that power medium-sized farms, running implements like bush hogs, disks, and plows day after day. When properly installed with fresh rings and bearings, this piston helps restore the power and efficiency you need to keep those tractors earning their keep.
Made to Last
Engine pistons take tremendous abuse from heat, pressure, and constant movement. This one’s built with the right alloy and heat treatment to handle the demands of diesel combustion while maintaining proper dimensions through thousands of hours of operation.
Good to Know
Make sure your machinist measures bore taper and out-of-round before deciding on .020″ oversize – sometimes cylinders need more cleanup than they first appear. Always use new rings with a new piston, and have your connecting rods checked for straightness and proper bearing clearances during assembly.
