Hi there thanks for your help that’s saved me messing around and a load of work and money. I’ve stripped the pump out today and removed all the broken bits maybe I can order the new parts I need onlineThey are not the same. I crossed a 900 pump with a x900 pump and they are different. The pistons on the assembly block are lapped into the block, meaning you can not change the pistons around inside the assembly. Even if they were the same I would shy away from that. These hydro units are precision units. Putting used parts into one sounds like a recipe for disaster. Taken care of they will last a long time. It seems to me that most failures on here are due to poor maintenance.
