When your Deutz tractor starts burning oil or loses compression, it's often the piston that's telling you it's time for attention. This piston and pin assembly gives you everything needed to restore that cylinder back to proper working order. Whether you're doing a complete rebuild on your Agroprima or just freshening up a tired DX cylinder, having the right piston makes all the difference between a repair that lasts and one that has you back under the hood next season. What You're Getting Complete piston assembly with 35mm wrist pin for proper connecting rod fit Four-ring design provides excellent compression sealing and oil control Precision-cast construction meets the tight tolerances Deutz engines demand Direct replacement that fits without modifications or special tools Quality materials built to handle the heat cycles of air-cooled operation Built for Real Farm Work This piston fits the legendary FL913 air-cooled diesel engines that power everything from compact Agroprima tractors working in tight vineyard rows to the bigger DX models pulling implements across open fields. These engines are found in some of the most reliable tractors ever built, and when properly maintained, they'll run for decades without missing a beat. Made to Last Deutz air-cooled engines are built to last decades with proper maintenance, and using quality components during rebuild ensures your engine will deliver reliable power for years to come. The four-ring design gives you that extra sealing power that air-cooled engines need, especially when working hard in dusty conditions where every bit of compression counts. Good to Know Installation requires complete engine disassembly and is typically performed during major engine overhauls along with other wear components like bearings, rings, and gaskets. Don't forget that the rings are sold separately as part number 54156. The connecting rod bush must be properly sized and fitted using precision reaming or honing to achieve correct piston pin clearances. Take your time with the measurements - proper clearances are what separate a professional rebuild from a comeback job.
