585 Feeder chain jumps a cog, and continually plugging
Feeder house keeps plugging in heavy wet wheat, still green straw, and getting worse as the straw gets drier.
At first it would plug whenever crop was leaning(flat) towards the combine, and it went under and around the table auger (Claas F540 flex auger header) and made a lump. Stripper bars were set with a huge gap, set them tight, and eliminated the wrapping, and quit plugging for a while.
Then plugged on absolutely nothing, unable to reverse, just slipped the belt. Removed header and tried to reverse with a 5' bar in the feeder chain, it locked right up in each direction with a metallic clunk after only a couple inches of hard fought travel. Eventually broke it loose with the bar and cleaned it out.
Discovered that the backwards bolts were hitting the supports on the underside of the center floor of the feeder house. And hitting hard enough to stop the feeder chain in heavy going, damaging the bolts and the supports, and making lots of noise. Replaced them with shorter bolts( then just now I read on here that they are there on purpose to clean off the sprockets...).
Ran much better without plugging for a while, then started skipping the chain( far right). Under proper tension, then plugging. Lots of material under the top chain on the edges, not sure if it gets there from reversing or from feeding.
There are no guards at the edge of the feeder house entry to keep crop away from the edges, doesn't even look like there ever has been. The 8460's had sheet metal guards both sides and top. I read on here that there should be, or at least "triangles" welded in the bottom corners. Can someone clarify what those should look like, preferably with a picture?
If I add side guards, can I leave the backwards bolts out, or are they still required?
This has the poppet type of slip clutch. Do they wear, and can they be set tighter? Wondering if the clutch slips too easily, causing a minor plug, then when I reverse it, it backfeeds and gets material on top, leading to more troubles the next time, and the next time...
It usually takes multiple attempts back and forth to get the plug out, and sometimes removing the header.
Running very close to 100% engine power all the time. 2 to 4 km/hour, and as high as 2000 bushels per hour, now that I have all the kinks worked out in the rest of the machine, it is handling this tough straw no problem at those rates.

Reason: To bold the main points, since the post was way too long to expect anyone to read it.
