[QUOTE="7LBSSMALLIE, post: 95052, member: 6879"] the reasoning behind plastilic coupler? shear key.. if a relief sticks closed somethining has to give. preferably not a 5000..00 pump or 10.000 eng. first step inspect cyl rods for bends or flaking. ( source of contanintaiments) most likely you have a relief stuck closed. therebye strippining weak point ( most inexespenisve component). which is is good? now how to detirme which component is causining failure? you mentioned clamp thumb whatever. which should have a port relief. might be time to take to dealer. the 341 will also benefit from what I refer to as a hyd tune up. basicily flow check pumps . press check main and ports set to hi side of spefcations. the difference between 100 psi as transmitted to sticks will amaze you. springs get weak . pressures need to be readjusted now and again. so in closining my thoughts you got a relief that wont opn shearining weak spot . how would approach this is flow check pressure check and adjust accordingly [/QUOTE]
