Description
When you’re facing white or blue smoke at startup, oil burning between rings, or that telltale knocking sound from a worn cylinder, it’s time for new pistons. This replacement piston gets your David Brown engine running smooth again, whether you’re rebuilding after years of hard work or upgrading worn components during routine maintenance.
What You’re Getting
- Precision-machined 100.05mm bore diameter for proper cylinder fit and optimal compression
- Quality construction that handles the heat and pressure cycles of diesel operation
- Direct replacement design—no modifications needed for proper installation
- Durable materials that resist wear and maintain tight tolerances over thousands of hours
Built for Real Farm Work
These pistons fit David Brown tractors from the smaller 43-horsepower 885 models up through the versatile 46-horsepower 880 series machines used for mixed farming operations, cultivation, hay production, and livestock management. Whether you’re running a compact utility tractor for estate work or a mid-size machine for serious field operations, this piston is engineered to handle the demands of agricultural diesel engines that work season after season.
Made to Last
Farm tractors don’t get babied, and this piston is built accordingly. The precision bore dimension ensures proper ring seal and compression while the robust construction handles the thermal cycling that comes with daily startup, hard work, and cool-down periods that can stress engine components.
Installation Notes
Engine rebuild work requires proper tools and experience—if you’re not comfortable with piston installation, ring gapping, and torque specifications, this is a job for your local diesel shop. When installing, always replace rings, gaskets, and seals as a set, and check cylinder bore condition before assembly.
