Hi all -
I have a 12.5x60 Hydrashift that I bought about a year ago from someone who had it in storage for about 15 years. When I got it I topped off the headstock hydraulic oil and tested it out to make sure everything worked before I tore in to the mostly cosmetic restoration. Everything seemed to shift like it should at that time.
Fast forward about a year, I finally buttoned it back up and got it wired last night and spun it up. The spindle IS spinning, but it is stuck in a single gear and I can not get it to shift. Absolutely nothing happens when I turn the shifter knob and stop/start/jog the clutch.
I can confirm that the pump is moving hydraulic fluid. (I had to do some work on the pump during the rebuild - new seals, had to re-key the shaft and pulley). I did clean the external filter but didn't mess with the internal one at the time.
I haven't checked pressure yet, but will probably throw together a gauge if I run out of other ideas.
I never removed the shifting assembly and didn't do anything to the interior workings on the headstock. I did poke around in there just seeing how things worked and I most likely did move some of the shifter "forks" around manually. My only theory at this point is that I moved something and it's out of sync somehow and doesn't know what to do....but I don't know how to get it back to where it wants to be or thinks it is.
Any pointers on where to troubleshoot this? I don't think I messed up anything major, but I'm really not sure where to begin...
