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?
we did this to our 07 7010 big job but didn't take us that long. we don't have a chopper so don't no if that would make it harder.. we dropped the sieve box down as far as it could go took the spreaders off undid the pan and slide it over the top of the sieves and sieve box was hard and took some time but we had it out in about 3 or 4 hrs with 2 blokes. the sieve box will move about 3inchs down this makes it enough to get it out.
is some little thing you can do to help it come out we took the pan rubbers off the ruber flaps along the side i mean.
Worked for us if you want to PM me i could tell you some more but i tell you it can be done.
sorry I don't have any pics but i get my mech mate to get on a tell his version of the event.
the biggest thing is to get in and start that why it took us so long because we kept thinking about it.
our pan was cracking side to side towards the front behind the rubber flap didn't notice at first until we cleaned it off. started out small crack and got bigger. we wire welded ours to get through the year then dealer put in new one . free of charge no problem with new one.
