Some manufacturers claim their engine parts meet or exceed John Deere specifications. However, these look-alikes cannot compete with the continuous technology improvements of genuine John Deere parts. Even though the differences might be small, the advancements make a big difference in retaining the performance and reliability of John Deere engines.
Camshafts serve a vital role in air, fuel, and emissions management on John Deere engines. Camshafts determine when, how long, and how fast the engine valves open and close. This is one of the most critical elements that govern engine performance. The slightest variation from the camshaft lobe design can negatively impact power output, fuel efficiency, and emissions control. Genuine John Deere camshafts are specifically designed to maximize performance and maintain emissions compliance.
