Back door can be done with one person but it’s not easy. Our 670 is about a foot higher then the 780 so makes it a bit trickier.
You do plug less with more experience but slow cylinder speeds will cause a few and not much you can do about it. In cereals and canola most plugs are caused by operator error.

That shaft twisted for pivoting the rear panel made it a lot harder to install, the handle stops it from going all the way forward and laying down properly so we had to have the panel standing more vertical to bolt in place. Got it to lay down now so should be much easier for one or 2 people to lay the panel flat and then bolt in. Now that I understand how it is supposed to work, I can see it being easier.
Question on speed sensing, I think this is where I am causing my problems:
The cylinder doesn't have a speed sensor that I know of, it is on the aps drum. Does the impeller have a speed sensor?
My "threshing drum standstill" could very well be the aps drum plugged, not the cylinder. If so, that changes how I adjust things. I mean, it won't ever say "aps stopped", will it?
How about the impeller, does it have a slip/plugged warning?
Yesterday I plugged it, couldn't get stone trap open, so loosened aps belt. Started it up, cylinder speed read zero as expected, but no "drum stopped" warning. Some how it knew the cylinder was turning even though aps was stopped. I would guess there is a speed sensor on impeller but haven't looked at it.
If I understand this better, and it is my aps plugging, then I should look at running the aps belt tighter. It would make sense the aps is plugging in a bushy portion of peas. It's why I can't understand why the cylinder would be plugged, because it probably isn't. I am misunderstanding the alarms. And if it is the aps, maybe I should look at cutting back some flighting on the Honeybee drum. It has retractable finger across about a 4.5 ft width but flights in behind some of the fingers so there is only about a 3 ft width with no flights. The feed drum is trying to force more crop to center of feeder chain than perhaps needed. Don't know, just curious if others have done some changes here. Pickup headers don't usually have flights behind fingers. Draper heads do.

You are correct that the speed reads off the aps. Impeller should also have a speed sensor.
We cut the flighting back on our macdon header to not feed the middle so much. That’s on a wide body machine. You still want it pushing the crop inside the widest area of the feeder house. If it builds up on the outsides the chain can jump.

Ok, good point about build up on sides and chain jumping.
Yeah, how it senses speed changes everything for me. My cylinder plugs were not cylinder plugs, they are aps plugs. It's why I couldn't understand how the cylinder is plugging, there is no way a cylinder should plug in what I am trying to push through. Feeder house or draper drum should be plugging. But an aps plug, yes I can see that happening.
My fault for not pulling left side cover on cylinder and looking I suppose. But it's terribly missleading to have a label specifically say "threshing drum", where the designers know very well it could be threshing drum or aps. If they don't know which one is stopped then the alarm label should also reflect that. Not too hard for label to say "threshing drum/aps standstill".

I’ve learned to not try and understand the logic in the German thinking.

Plugged the chopper one more time. Last 100 yards of Peas. Found out that plugged chopper sensor is pooched, push in the plunger and still says open circuit, so bent the panel again. Good news is while I had panel off is a good time to flip knives. Was not looking forward to that job but quite nice with panel off and a pallet on small tractor front end loader to sit on right level with chopper drum. Knives wore down pretty good Nearest the walls. The peas really took the edge off the knives so no doubt a source of my problem.
Doing a good job in wheat. My settings ended up being very close to cemos auto so let cemos run seperation and cleaning after I got comfortable with it. Cylinder at 810,concave at 7mm, APS with square key stock grates and flaps closed.

Cemos is pretty good on cereals. Canola it’s a little off. I know lots of guys who don’t use it when doing canola. Mustard likely be the same way.

Hey kenmb, you'll be a pro on that machine by the time harvest is over!

Getting the machine figured out, I really dislike getting different machines. Much prefer being familiar with a machine and making it work better rather than get a different machine to solve an issue with the previous machine.
Got my cylinder down to 740 rpm, was reluctant to go lower as my rotor loss is limiting but seems the slower cylinder is working ok.
Claas engineering: That swing down panel that creates the floor of the rock trap. Not understanding why it has that swing arm arrangement but I broke it twice yesterday. Broke on left side where that hand knobs is, welded it, and half hour later both arms broke. I read on other forum about that panel being bent, I assume that means bowed like a smile. Will look at it this morning. Don't understand why that piece isn't bolted to the frame.
And got water dumped on me and control panel from the ac vents on either side of radio. Drain tubes are clear, used blow gun to verify air passes through. Get some water draining out but must be some blockage in water catch pan not allowing water to reach drains. Will look today if a guy can pull a panel off roof to good access. Don't mind the water on me, don't like water on screen and control stick and panel.
More to learn it seems.

You should be able to get to the water catch pan by taking the roof panel off.
Was have a spare panel for below the rock trap. When it’s broke we swap it out then fix it. Seems like if the crop is slugging through it will break

Ok thanks Meskie. If breaking that rock trap panel is not uncommon then I don't mind getting another one. One of those spare parts a guy learns to keep in inventory. It is what it is.
Might be some mold or dust in that pan creating a dam around the drains, could be one of those once every 4 year service interval items.

Check on yours if it has washers on the side so the arm can’t fall off if it breaks. Then you have to make a new one if it happens. they didn’t come with them a few years. We put washers on them and the dealer thought it was a good idea so started doing that on winter inspection. Then the factory put them on

Don't want to scare you kenmb, but make sure the shaker bushings are good on the combine. If they get too much play in them the grain prep pan or whatever you want to call it, will start hitting that rock trap panel. Not likely your problem, but I had that happen on my 480.

im blaming Ken for this one. ouch. That doesn't look good. How did your aps grate holders get yanked up like that? I guess that's lower, those hold the catch pans? I'll have to look at ours.
