Hi Everybody!
I'm always reading up here but don't post that often, most of my questions have usually been covered in previous threads. Have had some serious help from here in the past and am very thankful for that. Lotsa what I know about machinery, construction, farm mechanization etc. comes from this website.
Sooo, gotta good one for anyone who likes a challenge. 1997 Deere 310D backhoe with what appears to be a reverser problem. Forward is weak when it turns on but at least it'll move, when it warms up no forward at all. Reverse always works fine with what seems like full power. Had to drive a couple kilometers back to the mechanic in reverse today, at night in the rain. (why am i always in these situations?)
Just installed a whole reverser rebuild kit with the charge pump and the torque converter as well. This thing that the mechanic is calling the "servo piston" (in spanish, Costa Rica) although the Deere parts manual just calls it a "housing" (part no. T101010), had some scratches from these rings around the drive shaft that goes through it. We took it to the machine shop and the dude put a sleeve inside it and it looked really smooth and clean.
Put it all back together, worked fine at first but halfway home it started to lose power again. Totally new insides and it's worse than before. The mechanic seems like he knows what he's doing, it looked like he'd done it plenty of times before. But he's at a loss. No oil squirting that I can see, and there's plenty in there. It has to be losing pressure somewhere in the forward direction, right? Although I dunno much about how these things work.
Do Solenoid problems ever have any symptoms like this? The clutch solenoid doesn't work but it hasn't appeared to be a problem yet, just shift while it's in neutral. The FNR solenoids always seemed to work, and like I said it works when cold but loses power fast as it heats up. But I dunno what other variables there could be.
Anyone have any Ideas, any clues at all?
Thanks for any suggestions,
Sebastian
