When I rebuilt one of my Valk Rears, I could put the GW ring gear, bearing assembly in the valk rearend just to see what would happen and it rotated fine. Non problem. I did not use it that way, I pressed out the splines and swapped them. The ring gears are virtually identical. The GW ring gear might have required a different shim between the big bearing and the ring gear. There is also a 'Gear Stopper Pin' item # 15 on the fische that goes on the Gear Case Cover, item #8. It could have been rubbing if the cover was on. At any rate, you cannt use the GW ring gear because it would have a different wear pattern and would not 'mesh' properly with the pinion gear. Would probably whine like a banshee.
I'm whining like a banshee myself right now myself.
Both ring gears and bearings pressed off the spine shafts just fine. When pressing the goldwing splineshaft into the valk ring gear I heard a "ting" just as it seated. Had to use a lighted magnifier to see it but the bevel gear has a hairline crack now where the splines pass into it.
I've got a guy who does a lot of tig work for local industry and does my firearms tig work for me but I'm just not sure about having this crack tigged up. He might be against doing it anyway.
Guess I'll look for another valk hub on e bay with worn out splines and rebuild it instead of rebuilding my old one.
I retrospect, I realize what probably caused it, it was my own press technique. I pressed the bearing on first, intentionally pushing it a little deep. My plan was that the bevel gear would seat against the bearing and push it the last fraction of an inch as it seated on the shoulder of the shaft. Evidently that was a little too much for the bevel gear.
