Howdy all, I got the remotes on and working on the 1755, new hoses, old couplers. One valve works perfectly. The other has a problem.
One port (base end or rear port) will not flow enough oil. I've sort of diagnosed it to be the interlock pin is broken or the plunger is stuck. That's what the White technical service manual guides me to. But, there are two other possibilities too. The first being the spool itself, I may have installed it with the arrow up (I don't think so, but I can't get a good look at it with it in the tractor), I don't know what kind of problems that causes though, and the second being that when the check ball fell out while I was installing them I may have put the collar retainer back in upside down (again, I don't think so, but it's always a possibility) The channel in the outside of the retaining collar holding the pin would be on the ball end to line up with the interlock port to allow oil flow through it. Near as I can tell that's how it works anyway. These port fittings are impossible to put on or remove while the valve is solidly mounted on the tractor; the new 90° hose ends that were put on the new hoses weren't the short elbow type like before, these are a quarter inch longer hanging down, this causes some interference with the axle mounting bolts on both ports. No leakage now, but that might be only a matter of time.
Can these internal workings be worked on with the valve spool in the neutral position without draining the hydraulic fluid? Or is there still a path for the fluid to drain out at the valves?
I'm worried the fluid will get contaminated out here in the gravel drive, even using the new buckets with all the flying insects and dust coming off the road when folks drive by. That's some pricey stuff as we all know, and this is all new fluid. (Deere Hy-Guard)
Naturally this is the inner valve not working right, near impossible to work on or get to to see. The base end in the rear is probably in a position to work on while still on the tractor, the front isn't even close.
Take em all off and put them back on the bench? And then squeeze the wallet and buy new oil...
Any thing I may have missed? Any suggestions? Shortcuts?
Thanks!
