When your diesel engine starts burning oil, knocking, or losing power under load, those worn cylinders and pistons are telling you it’s time for some serious attention. This complete overbore kit gives you everything you need to bring that tired 4-cylinder diesel back to factory power without the cost and downtime of a complete engine rebuild.
What You’re Getting
- Complete set of precision-ground sleeves sized from standard 4-1/8″ bore to 4-1/4″ overbore for restored compression
- Matched pistons, rings, pins, and retainers engineered to handle diesel combustion pressures
- Everything for all four cylinders in one kit – no need to piece together separate components
- Quality TISCO manufacturing that meets original equipment specifications
Built for Real Farm Work
This kit is designed for the A267D 4-cylinder diesel engine, which powers various tractors and equipment used in row crop farming, hay operations, and general farm maintenance. Whether you’re running cultivation equipment, pulling implements, or powering hydraulic systems, this engine needs to deliver consistent power season after season.
Made to Last
Diesel engines face extreme pressures and temperatures, so this kit uses materials built to handle the punishment. The overbore design gives you a fresh cylinder surface and proper ring seal, while the matched components ensure everything works together for reliable performance and long service life.
Good to Know
Going from 4-1/8″ to 4-1/4″ overbore means you’ll need to have your cylinders properly machined before installation. Make sure to check cylinder taper and out-of-round measurements first. This is typically an in-frame rebuild, but having all the right tools and a clean work area makes the job go much smoother.
