I have a 7200 with a 3 cylinder mits. It blew a line on the loader so I removed it per the directions on the sticker. When I went to reinstall the loader the pressure pipe,which has a previous repair, sprung a leak..This is the pipe which runs from the hydraulic pump on the left side of the motor to the hydraulic hook ups on the right side. When you remove the loader, you have a hose left on the tractor, should this hose be connected to the fitting on the hydraulic block. Did the pressure pipe blow because that hose was not hooked back into the system to relieve pressure? The pipe is $310 any suggestion for a cheaper fix. The Pipe has been brazed in the center section where it goes under the motor. Think I could replace it with a hose.
