How does one go about changing the drive belt for the sickle on the 880 corn head? the belt on it has seen better days and I'm thinking I should replace it before we get going too hard. I couldn't fugure it out looking at it.

Here Donovan these pages were scanned from the 880 chopper operator manual and pertain to the 880R1and 880R2 corn heads. They should help you out.
 
Thanks ihman, that should help me get it. Do you know if that is just a regular off the shelf belt? Or is it a NH only thing? Hopefully I can get the belt off today, and then have a new one to put on by the time the pulley gets here that bolts to the reversing gearbox.

You were asking about row crop heads a few days ago for the 892 chopper that you had bought. From what I'm reading here now, you must have found one. A model 880R2 (wide row) or 880N2 (narrow row)? I liked the 880 head more than the 824 I'm using now.
 
Its a wide row head, but we have 32" rows. Thats ok though as we are retiring a fox 3000 with a wide row head as well so I know it'll work. Next year we may look for another head like an 824 just because the one we found has for sure seen a lot of acres. Probably still keep this one though just in case.

Only paid $400 for it, plus another $130 for the pulley that drives the sickle. That should be getting shipped out tomorrow so it may be here on tuesday. The local branch for the same dealer had a p.o.s 824 head for a mear $995... We told them where to stick that head. Maybe next spring they'll sell the other head they wanted $2500 for it for $1000. The pos they had listed for $200 earlier in the season but we thought we had a head that would work.

Really a shame that 770 head wouldn't fit as it really was in nice shape.

I managed to change the belt tonight, but I think I took it apart a little farther than I should have. I got the spacer out under the pivot mount under it, and took out the bolt holding it to the sickle. I then ended up having to remove the 2 bearing caps on the sides to get enough movement to get the belt underneath it.

The belt on it seemed too short, and snapped when I was trying to get it over the pulley. I found a worn belt from our Gehl 72 green chopper was only about an inch or so longer, and fit very nicely. I still want to replace it with a new one, but if this gets me by it may stay on for a while. We've got one more even older belt off the same model green chopper in the shop from the last time Dad changed them probably 20 years ago. Good thing we never throw some stuff away....
