I have an old 66 baler that I have used the last few years. Yesterday I broke the chain that runs under the plunger. I replaced it however I don't know If I got the timing right for the wadboard in the back of the baler that runs parallel to the auger.

I have a users manual and have the timing set for the plunger and needles but I can 't find anything about the proper placement of the back wadboard that pushes the hay into the chamber to be cut and baled.

Anyone have any ideas?
