550b case feeder hits frame

I just installed a casefeeder on my 550B, and have 2 issues. The casefeeder hits the primer rod when raising the plate, and at top of the stroke, the case feeder contacts the frame and I can see it is more than slightly 'deflected'. It deflects enough that the conversion adapter and the drop tube get deflected also. I dis-assembled the platform, loosened the screws and moved the casefeeder very slightly away from the primer base. The alignment tool goes in perfectly. I did bend the primer guide rod a bit, and added a little piece of 1/4 id polly flow tube to the guide roller shaft, and I think it is functioning ok, but I do not want to put any strain on the feeder when it tops out. I thought of putting a 'gasket' spacer under the main plate, between the case feeder, but thought it may cause issues when feeding cases. I don't want to use it like this. Any ideas?

Here is a video that shows the amount of deflection.

RE: 550b case feeder hits frame

I put a .040 spacer between the casefeeder mount and the top plate. This would cause feed problems, so I took it out. Then when I was feeling around where the casefeeder was contacting the 550B frame, I realized that there was a little bit of a bump there on the frame, right at the corner. I think I will have to grind 2 small spots in the frame to allow the casefeeder to complete its travel. I'll do it tomorrow afternoon.

On the early 550 frames, a little bit of the frame has to be cut away to provide clearance for the case feeder. We use a die grinder to do this by hand in-house. Not much has to be removed.

Thank you. I did that and all is well.
