A friend with 3 7010's had all the feeder chains replaced this summer all warranty.
They have full width slats, I replaced every other pair, takes 6.
I thought the 20's all had the larger drive sprokets.

We have an 8010 that needs both feeder chains. Like dap54 said, they recommend putting 6 full width slats across both chains to prevent jumping. Anyone had good or bad luck doing this?

What I don't get is that NH has had springs on their feederhouse for as long as I can remember and chain jumping was never a problem. Sometimes I wonder why they don't take what is working on one combine and put it on the other.
?

We had the feederchain skip on our TR when it was behind (wait for it...) a macdon header!

Smooth feeding (Honeybee) for the past 2 years and have not skipped a tooth yet. Slugs will cause them to jump.

We had this problem with our 8010 last year when it was new. We finally took the spring off and put solid bushing in place of spring. We have not had any problems in the last 500hrs. If you run the spring and the drum gets pushed back on one side it has to jump a tooth on the sprocket. I don't see how the spring would ever allow it to work properly. If Case wanted the drum to move backwards in certain situations it looks like it would have to be designed so that if one side of the drum moved backwards the other side would have to move at the same time to keep everything square.

they will be replacing the feeder chain tomorow, i will see that we tighten it to the pipe rather than the spring guide, just pees me off that this probally is the reason that the feeder shuts off early and we never found it till now

i had two honey bee 36'headers before tha 40 foot 2152, i like the honey bee but hated all the knife repairs, spent close to 5 grand over 3 years, and no support from HB, now with one year on the 2152, it will cut as good or lower, never hit the ground, and no knife or head issues, but does have a dual drive,and i think feeds as good as the hb

full width slats on 8010 7010's why the f didn't they do it in 03. feeder is to long i think but has to be for the size of the combine. keep the spring loaded ones over tight.

I put 6 full slats on my 06 8010 last year before corn harvest, works very well. I just combined a 1000 acre of pinto beans and still havent had to tighten the chain. When I had two seperate chains the centers would always droop and wear more than the outsides. I think the full slats even the load and the wear. I didnt try it in the wheat this summer, used a 7010.

had this problem on our 7010 and haven't solved it yet but if you keep new chains in and keep them tight we have less problems. but would be keen to see some full slats working. what is the CIH part number?

we replaced the chain today, the old chain was warped badly, and was wore out on less than 125 hrs, lol

we never found any reason why it happened, so i hope the new one does not follow the same path
