NH 271 baler

firsttime

Our baler quit. We baled the first 100 or so and then it started breaking shear bolts. Needed to be re-timed. When my son timed it, the needles come back , but not far enough to pull the safety latches back out of the bale chamber. He timed it again to adjust that and now the marks are pretty far away (pic 1). I am assuming that the needles and knotters are now out of time. Can't try it because of the rain. In addition, the rod that operates the needles on the other side is hitting as it comes around (pic 2, near top arrow). This rod has been broken and welded in the past. PS. We baled 1500 bales last year with no problems. Any help would be appreciated. Thanks.

Sometimes the marks are not accurate try timing it manually while turning it over by hand and make sure the needles come up right behind the plunger and when that is correct you may have to adjust the needle safety latch and the needle yoke rod either find a good used one or buy a new one somebody may not have welded it back together correct and now it is getting in a bind HTH
 
Are you timing it with the book? Need to have the plunger in the right spot (mark) and the feeder fingers in the correct spot(mark on the back of the baler opening)...chain in the correct path?..per manual. I bought a 270 (same baler) previous owner had the chain path was all wrong. Take the drive chain off completely and hold the plunger and feeders and knotter in the right spot then put the chain back on correctly and tight. The marks on the knotter can be off just a tiny bit and still be OK.

Is the welded shaft the proper length? looks short.
 
Concentrate on the fact you baled some last year with no problems. Unless you had the arm welded, it's not an issue.

Best advice is to get a manual and follow it precisely. Make sure you take all the hay out so you can roll it over easily and verify it will work.

When it is timed it will not break shear bolts. Also make sure you are using shear bolts and not grade 2, 5, or 8.
 
You need to get a manual. These balers are easy to time, but IMHO, the key is starting with the plunger to needle tips per the manual. You might have to remove the chain on the knotter gear to get the lines to line-up. It?s been a while since I had to time my NH68, but it is really simple and straight forward, But start with the needles as they enter the bale chamber and their position to the plunger face. The manual clearly shows this.

With credit card, you can download a pdf of the manual from New Holland for not much $$ and have it in a few minutes vs a dealer order.

Good luck,
Bill
 
What they are saying below is right. Also take all of the hay out of the baler and start from scratch on your timing. Replace the rod that has been welded because that adjusts the home position of your needles. I should have that rod if you need it.
 
You'd better get a manual. Only adjusting one or two settings could throw others off. You need to go in a sequence. My 273 started breaking shear bolts and it was only a matter of tightening the knotter brake. In your second picture, the joint at the top arrow should be a little past the centerline between the knotter shaft and the needle yoke. Yours is a little short of center. And whenever you check the timing you have to pull that joint back until the knotter clutch stops against the trip arm. Pull it in the direction of the top arrow. Takes some time to learn but once you get an understanding of how everything works together it's not too bad.
