JCB

JCB (J.C. Bamford Excavators Ltd.) is one of the most recognised manufacturers of construction, agricultural and industrial equipment in the world. With a strong presence across the UK, Europe and global markets, JCB machines are known for their robust build quality, versatility, and powerful performance — all backed by highly efficient engine platforms.

JCB uses both in-house manufactured engines (JCB Dieselmax) and third-party engines (including Perkins, Cummins, and Kohler) across its extensive equipment range. At AMS Parts, we supply genuine and OEM engine parts tailored for JCB engines and JCB machinery using compatible power units.
