Glad you guys are still fixing these things. I'm about to start rebuilding mine in a few weeks. Rotary swing cylinder works great, but all my bearings and pins are toast. I cross referenced the upper and lower bearings and found some same size units for cheap. That lower bearing is big bucks if you have to buy one brand new.
The flange that receives the splined shaft of the rotary cylinder--it has 4 bolt holes and 2 dowel pins. Well, mine is toast. All the holes wallowed out. Either I build up weld and redrill and tap it all. Or I was thinking about just welding the bastard solid. Weld it instead of using the bolts. The rotary cylinder will still slip in and out of it, but it'll be welded solid to the base.
Is there enough room to lift the rotary cylinder in and out with that flange welded in place? It was a last year when I tore it all apart, but I think I left the flange on the end of the cylinder when I pulled it. I'm afraid there isn't enough clearnence to leave that flange in place, and pull the swing cylinder high enough so the shaft can come right out of the flange.
Thoughts anyone? Can I weld that flange in place, or should I start ordering tooling to fix all the holes in the flange?
