Combines N6 feeder chain jumping teeth

[John]

last time I had a feeder chain jumping the sprockets, it was because the chain was old and stretched. I also found that when it was off for replacement that the bearings were getting tired, but not yet bad. I replaced the bearings and chain and haven't had a problem since. Good luck!

If chains and sprockets are in good condition you might try loosening all bolts, running the chain a few revolutions to center it, and then torque the bolts correctly. I have grade 8 bolts on my feed chains so I can tighten to 50 ft lbs for size 3_8.

Boyco, To further preload the the feed chains and break their bad habit,loosen the slat bolts,pry the feed drum over and drive the shaft through as far as you can,roll"er through 3 or 4 times and retighten the slat bolts.The chain is now preloaded the to the other side. Good luck, Hyper

Would you mind going through that again Hyper, I can't figure out what you mean. My N6 has the same problem. Thats with new chain and sprockets!! Thanks

Aussie, Feed chains are like children,they go to the path of least resistance.What we've found happens many times: The feed drum shifts on the drive shaft all the way to the right or the left,this causes the chain to be of slightly different tension on one side vrs the other.This condition continualy causes the chain to try and jump a tooth on the loose side.Continual operation can cause a chain to get sprung or canted slightly.The drive sprocket on the tight side also can wear at a higher rate.To reverse this drive the feed drum on the drive shaft as far as you can to the side with the widest gap between the drum and the feeder house.Now loosen all the slat bolts and rotate the feed chain to reset the chain.Tighten the bolts, and wala a retrained feedchain.

Can we assume you didnt install the chain with loose bolts and roll it over a few revolutions before tightening themIJ Some new chains are frequently sprung from mishandling or whatever causes them to be about half a bubble out of plumb. They will stay that way unless you straighten them in the machine as Hyper suggested. Tom in MN
