I find myself in a bit over my head. I had an allis 60 combine that had the clean grain elevator bottom rotted out on and the tailing auger trough was rotten also. I bought a 66 from a buddy that was in great shape except that the concave was rotten. Silly me... I thought I would be able to pull out the cylinder on my 60 and my 66.... swap the concaves and slap it all back together. This weekend I pulled the bin and the clean grain elevator off the 66 and also pulled off the outside door/ bearings on the real side of the cylinder. I'm looking at the rest of what I've gotten into and I'm looking for some encouragement and/or direction on how to proceed forward...
How do I actually get the cylinder out? I pulled the nut off the pulley side and took the tension off the belt. I put some heat on it and I figure that the pulley will come off eventually. But do I need to take the speed adjustment assembly off to get the cylinder out?
When I do get that done... do I drill / grind out the rivets holding the old concave in place? Do I then rivet in the new one or do I get some kind of domved machine screw?
Any other advice on how to make this as simple a project as possible?
