McCanna, ND | My 9120 is having a issue where it’s jumping the chain on the drive (LH) side. The front drum rolls true, bearings are good. 100 hours on a new drive sprocket. The old chain had MAYBE 300 hours on it. Put a new chain on and it jumped sometime today again. The tension setup had wore into the feeder house just slightly, I built it back and and ground it out smooth.
Nothing stands out as obviously wrong, where should I start looking?
Also just installed new wear strips on the rock beater. | |
