Brikers strives to have your main hydraulic pump rebuilt, tested, in stock and ready to ship. We stock main pumps for all the major manufacturers including Cat, Deere, Hitachi, Komatsu, Case, Linkbelt, Volvo & more! During rebuild if any part is not in like new condition, we replace it. This includes pistons, barrels, valve plates, heads, shafts, etc. All seals, o-rings, and bearings are replaced on every pump we do. We guarantee our pumps by testing each one on our brand new state of the art, 500HP electric test bench!
