Are you talking about the pan that's under the rotor?
My 07 8010 had a grain pan that was cracked on the right side, not easy to see but it was there. It was repalced before corn harvest. I had the combine at the shop long before harvest so the job was done on rainy and slow days. I saw all the parts on the floor. They took it out the back. I think they pulled all the seives and rails. I don't think they took the hyd.spredder off the back. If you don't get a better answer I'll stop by the shop and ask the guy who did the job. I think they replaced the pans in 2 or 3 other 8010's. What year is your machine and why are you replacing it?
