HELP .A ford 532 baler we were using pretty much self distructed after the rake that feeds the hay chamber broke and fell into the chamber. The ram hit it, broke the chain,and bent the shaft that drives the feeder. We finally got the shaft straightened and a new chain put on .We set the timing to where the needles were just coming up before the ram cleared them. We ran the baler empty numerous times. But when we started to bale, the teeth broke .I think it was the ram but not sure. How do i set the timing if I set it wrong the first time?
