My son-in-law was combining Canola and ran a couple slugs through the combine, he said the feeder house has a vibration now after running them through.Any ideas what he should check to remedy the situation, thanks

If your 9770 has the spring tensioned feeder house I would guess the chain is out of alignment. We have an 09 9870 and it is terrible. Have removed half links and tightened past the washer..... still jumps. Seems JD has no solution... Bill

John Deere's solution is to tighten the self adjusting bolts up to the bushing inside the spring.

I guess you probably already made sure the bolt through the eyebolt isn't bottomed out in the slot, thats why you removed a half link? IF not tighten the spring all you want and the chain won't get tighter. Just in case it was overlooked (but I get the impression by the shortened chain that was already checked)
