Description

When you’re hearing that telltale knocking sound or noticing blue smoke on startup, it’s usually time for a rebuild. This .040″ oversize piston is exactly what you need when your Ford New Holland 2100 series tractor with the 134 cubic inch engine needs more than just rings—when the cylinder walls are worn beyond standard specs and need to be bored out for a proper rebuild.

What You’re Getting

Precision-machined .040″ oversize piston designed for 3.4375″ bore after machining
Built to OEM specifications for proper fit and compression in your 134 CID engine
Quality construction that handles the heat and pressure of daily farm work
Direct replacement for worn pistons when cylinders are bored .040″ over standard

Built for Real Farm Work

This piston fits the 4-cylinder 134 cubic inch engines found in Ford New Holland 2100 series tractors. These compact utility tractors were popular for smaller farming operations, handling everything from loader work to mowing to light tillage. The 134 engine with its 3.4375″ bore and 3.600″ stroke was a reliable workhorse that responded well to proper rebuilds.

Made to Last

Engine rebuilds aren’t something you want to do twice, so this piston is built to handle years of service. The materials and tolerances match what Ford originally used, ensuring proper ring seal, oil control, and compression for dependable performance season after season.

Good to Know

This is an oversize piston, so your cylinders will need to be professionally bored .040″ over standard before installation. Make sure to use the correct oversize rings (sold separately) and have the connecting rod resized if needed. A good machine shop can handle the boring and honing to get the proper cylinder finish for ring seating.
