If you are going to change the concave, you should put a sunnybrook in
I Put a sunnybrook concave, cylinder, and wear kit on impeller in my 580r. I found it makes a difference. Crop goes through smoother and machine doesn't plug as easily.

 

That concave is called an N18. I think it is 18mm between wires. It is a factory, standard "large wire" concave. It is likely the most capable concave for various crops and conditions.

If that is the factory concave, it appears to be in very good condition yet, from this angle. If I had to pick an aftermarket concave, I would lean towards the HHS concave, as it has convenient changeable grates for it. I would try what you have before changing it. Do you have pics of the sieve you took out? I might be interested.

Yes and a small grain is 7mm front section/18mm rear.

That concave appears to have been sitting outside and not used since, did you get just the installed concave?

 

Here is the sieve. One 1/2 is rusty as ****

Can anyone tell me what these are for? They were in the tool box

 

Dan,
If those are your lower sieves we have a set of 10mm small grain lower sieves for a 580 we would trade you. Could the pieces in the tool box be the sidehill deflectors that go up near the front of the top chaffer on the sides of the machine? Good luck! Tiger

 

I would just stay with the concave you have with the crops you are harvesting and get yourself a few different APS grates the ones you will need will be the HHS soya grates and the small grains ones we have been HHS concaves in the last couple of Lexions so we could run full round bar for corn and mungbeans both of these grains being very low in moisture, but we have had no problems with the fixed roundbar part in harder to thresh wheat, barley and sorghum. If you ever have any dramas with the Claas drum get yourself a Sunnybrook drum they are the best built, smoothest running replacement drum I have had the pleasure of running. Don't be shy with asking any question on here no matter how trivial they may seem, there is definitely plenty of experts here....

 

I agree with aussie. I have run a 480 for 11 years that was originally a corn/bean machine. It had the oval shaped holes (18 mm) in the main concave and it worked fine. I did put in the Sunnybrook cylinder, 6.5 mm aps grates with keystock and intensive thresh segments for hard to thresh wheat and did not have a problem with whitecaps or returns. When I had the original concave rebuilt I did add 4 rows of filler bars under the front rows. Seems to work well for wheat and canola. Good luck with the 580.

 

Thanks all. We'll stick with what we have for this season, and see how happy we are with the sample and take it from there. As far as stuff to have on hand would be the filler plates for main threshing concave, ITS, and filler plate for aps. Could someone just give a picture or little description of where that filler plate for aps goes? Thanks again

Ow, ow, pick me, pick me!
There is a little lever on the right side by the glorious stone trap door, down is open, up closed.

Hopefully the five pics work.

The APS grates are available from Claas and others such as HHSparts.com They can be blanked off by pulling the dis-awning plate lever up beside the feederhouse.
Above and behind the APS but in front of the cylinder, the intensive threshing segment (ITS) can be installed. They don't have holes for grain to fall through. They are the chromed item installed as shown.
A blanking plate can be installed under the main concave from underneath. It attaches to the first few rows of the concave for the main cylinder. It is attached to the APS grate framework.
After that blanking plate, blanking strips can be added to the main concave rows. These strips are added to the top of the concave wires and secured with nuts on the lower side. These strips aren't shown in the pictures.

 

That's gotter, nice pics SC.

I'm surprised the APS runs 61.5% of main cylinder, in fact I find that hard to believe.

If so, combined with this

Note the swept back angle of the paddles on the APS, roughly 60 degrees from shaft centerline.
Combine those two items and the APS feeds fine in (insert any crop but peas) but peas can stack in front of the APS at high feed rates is my contention.
