The hydraulic pump casing cracked due to pressure too high. Tech at Hoye tractor said it was because a blockage somewhere. Anyone know what would cause a blockage and where it might be. The tractor is a Vietnam rebuild with FEL and therefore is not a detachable FEL so no couplings to be loose. Is there something in the FEL joystick valve that could get blocked. It was working perfectly till it blew oring which was replaced then seal started leaking so bolts were tightened a bit and then the case cracked. Brother in law welded the case up and put it back on and it worked the 3 ph but when he hit the FEL joystick to raise the bucket the pump exploded again. It must be something in the FEL control valve but I dont know much about how they work other than which way to move the joystick to make it work. Any one with advice on this or that has had this problem and fixed it please chime in. The pump is $549 so dont want to blow another one.
