I live in the Bahamas and have a 416 Cat back hoe that I am having issues with the swing and the steering neither one will come up to there required pressures on the end of there stroke < swing cylinders > and there very slow! I rebuilt both swing cylinder's today and it made no difference. can't get over 500 psi to the left and 1000 to the right unless I slightly pull back on the boom up lever it swings fast and at the end of the stroke it goes in to relief of 2350. any one have any ideas on what to do from here?? its not like I can call the local Cat mechanic, been doing my own mechanical work for 40 years but was pretty much a Ford guy and this one has me stumped. every thing else works fine except the steering and swing any one know were I can go from here, been reading up a little bit about how the hydraulics work and kind of points to a resolver valve problem???
