Anyone ever rebuild one of them.I can gt the rebuil kit.?????

rebuilding a hydraulic pump is not something you can do in your garage, special tools are needed, you need to know piston tolerances, and finally you need to test the pump after the rebuild (a screwed up rebuild installed on your pump is a lot worse than a screwed up rebuild on a test bench)

take it to a hydraulic shop, that is famililar with Rexroth pumps, otherwise contact Schwing, sometimes it is cheaper to buy new

Seals and bushings are all you going to get in a rebiuid kit. And that alone my not help you.Worn input shaft or rotor group and the rebiuld kit is useless. Buy new or rebiult and send the core in .
