I was going through everything went to cycle knotters everything looked to be working fine until I noticed the needles would only go half way back to home position. I would have to pull them back into home position by hand any ideas on what is going on? [Reply]   [No Email]

If this is the case then the problem is likely in the knotter clutch, (broken spring, worn or loose roller etc.). If the knotters complete their full rotation and the fingers stop in the middle there is a woodruff key inbetween the shaft and bellcrank that could be sheared but it is not very likely. It is IMPERATIVE that when you check anything these are in order first: 1. Check plunger to needle timing, inside the front cover there are marks that the plunger arm will center between at 12 o'clock. With the plunger there there are punch marks on each of the two cast parts of the knotter clutch, they should either align or be within about an 1/8" approx. IF THEY DO NOT LINE UP find out why. In your case I'd bet that pulling on the needle yoke rod as described in my previous post would put it back in time. Then after cycling it does it again, I'd suspect the knotter clutch. EDIT P.S. I forgot to add If you only pull the needle yoke back til it locks and don't reset the knotter shaft by pulling the rod back this problem will persist until you do.

I'll bet the trip dog or TD spring is the problem. [Reply]  [No Email]

When you run it through a cycle do the needles return to the rear then drop down or stop halfway? If it returns to the rear then drops down try this first: Pull the knotter back until it locks then grab the rod running from the neddle yoke to the arm on the knotter shaft toward the upper end and give it a firm jerk, it should move about one clock position approx. Then try it, I have had this issue in the past and it cost me a service call from the old NH baler man in the area and it straightened mine out. He told me they can get out of place for several reasons. But it is a quick cheap trick, if it doesn't work we will help you any way we can. [Reply]  [No Email]

They will only go back until the bar they are attached to is vertical straight up and down. At that time I have to grab the bar and pull it into home position. There are no springs broke it is like it will slip alittle on the way down and not go any futher. [Reply]  [No Email]

The pawl also has a roller on the inner end and there is a block on the inside of the knotter clutch half that the pawl arm roller comes up against to actually drive the knotter shaft and needles. All these parts are located at the left end of the knotter shaft behind the drive chain. Roller could be flat spotted, block could be worn out. [Reply]  [No Email]

The needles will definitely get out of time if this spring is missing. Make sure the plunger safety stop is adjusted correctly also so it can do its thing if needed. That said, there are several folks on this forum with vast knowledge on NH balers and knotters. I just try to learn as I go! Lots of good help here. [Reply]  [No Email]
