John Deere 4.5 L with Auxiliary Drive SE500712

👉 NOTE: Auxiliary Drives are used to power auxiliary hydraulics or air compressors and are mounted to the engine front plate, which requires a different timing cover and timing gears vs non-Auxiliary Drive engines.
These are mostly found on industrial applications and are not always used.
If your engine has a mounted auxiliary drive and is required for your application, you must replace the engine with the same design.
But, if your engine has an auxiliary drive and is not used, you may be able to replace your engine with a non-Aux Drive engine and we always have more of these available.

🛑 Send us four (4) images of your engine (front, rear and both sides) to help us ID your best option.
