Anyone here got the hydraulic schematic for the outriggers on a RT58D serial 73875?
If its like the older rt58 all 4 OR are teed to one spool valve then each one has a solonoid valve on the piston side of the cylinder. What kind of trouble are you having
One side of the OR are all tied into one valve section, but the other runs to to some kind of round junction behind the cab. My problem is the outriggers only moving a few inches and stop after they were rebuilt, 3 leaked badly, marked the fittings and hoses but mabe the shop accidentally swapped them or something or this is pre-existing as they didn't want to move muchbefore resealing them.
Did they get new holding valves or rebuild them? Pressure relief could be set too low. Could be a rust crud ring in the barrel where the seals were sitting for so long? You would think they honed the barrels. Are you sure you don't have air in them? I stroke the lever until the cylinder just starts to move one direction, and then go the other direction, to get the cylinder full of oil, before I run it all the way each direction. If they aren't full, they will kind of stick.
I think the shop re-used the holding valves based on the paint. I was wondering if the holding valves were air locking so to speak. There is a noise like oil going over relief but maybe its air. Thanks for your advice
Sorry, the way I worded that is a little unclear. It could read like there is a pressure relief setting within the holding valve. Which there isn't. The holding valve may just not seat correctly, in which case they just slowly allow oil to bypass back out of the cylinder. But that wouldn't be described as a pressure relief. The "pressure relief" being too low, would be the system relief, at the valve being set too low, which means when the function is activated, it doesn't put out enough pressure to make the cylinder move, before the improperly set pressure relief bypassed the oil. So that's two different things that need checked, #1 if the holding valve is holding #2 the pressure relief setting at the valve section. Sorry for not explaining that very well in my earlier post.
