Combines rebuilding concaves

[wildcat1]

What are you harvestingIJ Small grains need a good, sharp concave with high bars. Just about anything will work in corn. Probably the same with beans. Milo needs a fairly good bar height to knock it out of the head. Any time the bars are worn down to the wires you had better rebuild or get new ones. St.John Welding in St. John, Kansas rebuilds concaves and does a good job. I had them touch up my concaves last spring with their grinder. The bars were still high, but the front edges had a radius on them. Squaring them up really made a difference in wheat. Hope this helps.

I'm cutting mainly small grains, sww and dns. Do you know what the cost diffrence is between rebuilding and buying new isIJ

Obviously new is better, as there has been no stress on the steel whatsoever. Once the material has been bent, the strength has been compromised. The concaves built by loewen have the edges milled square, so you may want to take a look at them, and they are the most durable ones around.

I had two corn and bean concaves that were bent up not too badly and Vandenbrink's in Sparta were able to straighten them. They had tools made up to do this. My concaves were not worn out completely and still had useable life in them yet. The repair was reasonable compared to replacements and could not tell the concaves had been bent. contact Roy @ 519-775-2601

A few years ago I had my small wire concaves rebuilt in both of my combines by St John Welding. I really like the job they did. From you post I understand that you change from small wire concaves to large wire concaves for different crops. I do the same thing. When I changed from rebuilt small wire concaves to non rebuilt large wire concaves, and then back again, I had to change the pinch point on the concaves each time. This was no big deal for me but it is something you should be aware of to make your machine perform the best. You may not have to change the pinch, but you should at least check it the first time you change the concaves.

I had Estes Mfg rebuild the concaves and a third of the rasp bars on my 1660 last winter and the elephant ears the year before that. Very pleased with their work. Very little wear has shown and the concaves are guaranteed for 3000 hrs. It was much cheaper than buying new ones. I probably needed to change the pinch point on the concaves but couldn't get the bolts aloose to adjust it. Maybe someone has a trick that I don't know ofIJ So I just closed the concaves a bit more and speeded the rotor up a little. I had just a little more damage to the grain that I did with my very wore out concaves but I still wasn't docked anything. The guy that owns Estes Mfg posts on this site from time to time. I think he goes by the name of Don.
