Genuine John Deere Pistons are designed to exceed customers' stringent demands of minimizing downtime and ensuring quality and reliability. All John Deere components are manufactured and tested to the latest OEM specifications in order to restore the original quality and performance of your machine.
Critical ring grooves contain a high nickel iron based insert cast into the aluminum piston to assure minimum wear and optimum sealing. Piston pin bores are engineered to distribute stresses evenly to prevent bore cracks during severe operating conditions.
John Deere utilizes the latest advancements in technology. Many pistons for earlier models of John Deere engines have been redesigned with this new technology in mind to improve fuel economy, starting ability, and reduce white smoke.
The size and shape of the combustion bowl has been re-designed to reduce dead space in the combustion area. This change increased compression ratios and improved combustion characteristics. The result is lower heat rejection, improved starting, and improved fuel economy. The piston bowl design ensures original or improved performance while maintaining emissions compliance.
John Deere pistons and cylinder liners come pre-assembled from the factory to ensure proper alignment of the piston rings and reduce customer labor.
