Shell-plate not rotating occasionally - Revolution

[rougeqc21]

Got my Evolution humming yesterday and 3 times, when loading at 2500/3000 RPH, the tool head would complete a full cycle but, the shell-plate would not rotate.

On the cycle thereafter, it would rotate and the PowderSense station would stop things because it detected a double charge.

Anyone encounter this at higher speeds and know how to diagnose?

 

Currently decapping and sizing while loading

Stacked priming and manual powder measure

• Index Speed - 1
• Top Dwell - 2
• Bottom Dwell - 2
• Bottom Slowdown - 2nd hash mark after MIN

On my Evolution, I have had 3-4 causes for indexing issues:

1. Sometimes primers get stuck and that causes indexing issues
2. The index pawl adjustment screw on the left side of machine

3. Sometimes I had my shell plate too tight and that caused indexing issues. Loosening it up a bit helped.
4. The internal guide rod, screws were getting loose... added some loctite and now it works.

There should be guides for all this on the Mark 7 community.

  I had occasional non-indexation on my evolution, about one in 100.
I disassemble the press, well oil and grease and since it's perfect no problem.

The last issue I had seem to be related to some crud haven't gotten underneath the shell plate. I'm having a different issue now where it seems like the shell plate indexing lags as the toolhead approaches the top of the stroke and then it kind of clicks into place and slightly over rotates before returning to zero. Any experience with this?

This really covers it all. Index pawl is usually adjusted once and then one never has to fiddle with it. I actually had to file mine down a tad.

 

On the Revolution unscrew the primer retention screw and attach a plastic tube to collect primers. If a primer is somewhat mangled and did not seat and if it comes around a second time it will jump up the machine.
