I am in the last stages of getting my 3400 project going. This tractor had the FEL and backhoe removed when i bought it, so I ended up hooking it back up just like it was plumbed (assuming it was plumbed correctly) and after multiple attempts and blown hoses I finally decided something must be wrong. I finally got around to checking what valve is on the backhoe. It appears to me that both the FEL and backhoe valves are open center, non-power beyond type. Does this look correct to you guys? (backhoe valve has 14 lines, 12 of which go to the backhoe cylinders. FEL valve has 6 lines, 4 of them going to the FEL cylinders) If so, I think it is plumbed completely wrong. Right now the line from the pump is going to the backhoe first, then to a selector valve (which has one of the two outputs plugged), then to the FEL valve, then to the reservoir (which has one of the two inputs plugged). If I understand the system correctly and they are not power beyond valves, it should go from the pump, to the selector valve, then each output goes to either the FEL or backhoe valve, then the outputs of those should go to the reservoir "T", correct? Hydraulics are not my strong point but they don't seem like rocket science, just have to dig in and get my hands dirty to get some experience. Thanks for any help!
