More R6 help needed please.

Need help understanding how this concave assembly works. On the separator side on the front, the entire thing is covered. The cage sweep looks like it has been disconnected. The last thing combined with this machine is soybeans. Can this work in corn? Also the last photo is of my N 630 corn header. Something doesn't look right with the feederhouse header hookup???

That cornhead is set up for a 1981 and older combine, not yours. Can be made to fit yours with an adapter kit. The cage sweep normally was disconnected in corn but must be connected in all other crops. Can't tell by the pictures but, if the closed off cage door panel is just above the rear feed chain, this is normal....no square open holes used there.

Thanks for the response. About the header I was kind of thinking that a 630 N should fit somehow. I saw a kit in the parts manual online. About the cylinder, I have been cleaning out the combine and the last thing this combine did was soys. The pictures were taken through the hopper access panels to the cylinder area. When I opened the separator side access door, right in front of me was this closed off area. On the rear side (engine) of the separator is a regular grate.

Let's try and get the terminology correct here, cause you're losing me. Sitting in the seat facing forward, the right HALF of the processor is the threshing section......the left HALF is the seperator section. There should be square holes everywhere in the cage, except maybe the top/front section of the threshing side just above the rear feeder chain. There could possibly be a homemade cover over the very left end over the discharge paddles. All other covers ( if there are any) need to be removed for corn and soybeans.

All right. I am with you. Thanks for your patients. As you are sitting in the combine seat, the right front side of the processor is what's covered up. The right rear has a grate. The separator section has grates. drallis, if the front of the separator section is closed up, what does the small 3" or 4" auger that's at the bottom do?

[drallis]

That auger is above the rear feeder chain, correct? ...it doesn't do anything in your case....sounds like someone replaced the two original perforated doors/panels with the R-5 solid ones, which is the way all the newer combines are made. No harm from having the solid doors on the right hand THRESHER side of the processor.

I was working on the 630 N header a bit today. I have to take some shims out of the gear drives for the gathering chains and the half links on the chains. I am truly enjoying this.
Is there a specific way that the gathering chain sprockets need to be timed?

[stevemcil]

Generally they are staggared (flights) Can be opposing if chains aren't run too close together to where they hit each other.Mine are staggared.
Re-read post.Never thought about sprocket VS shaft changing timing.Might see how they are before shim change...maybe too late?

[david.bz]

I was thinking about running row 1 and 6 even and the rest staggered. The shims were removed because I wanted to lessen the play in the gears. There was a bit of play in them but i also don't want them too tight so they start to bind. Oh well, my operators manual is on its way. Hope it clarifies some questions?

[drallis]

Gathering chain lugs on a Gleaner (OEM chain) cornhead are longer than others and can't really be run exactly across from each other. You can get them close, but not exact. Only time I set chains like that is when I have down corn to pickup. Leaving them across from each other will limit your top harvesting ground speed. Factory setting (staggered) is best for standing corn and higher harvesting speeds, like over 4 mph.
