...break something more expensive? it's tempting to wreck it to end the misery ;)
IH 430 all twine baler: it will tie 10-30 bales just fine, then it will shear the (flywheel) bolt. running it under rated speed increases the number of times before the bolt shears the needles are just starting to enter when the bolt shears. due to the design of the baler i know the overall timing is right, otherwise the packer fingers would strike the plunger. would the problem even be in the timing? what wear parts should i look for that might cause it to tie early or late? i cannot find the book either, so i'm pretty p.o.-ed since it isn't where i put it.
if anyone has hints of where to look it would be appreciated. thanks

also, driving through rough spots/ruts seems to aggrevate the problem

Are there any roller chains involved with the timing on your baler? Stretched chains can change timing just enough to shear bolts. Taking links out or just taking up all the slack won't cut it, because, say the lenth of 20 links of new chain is 10" long but the lenth 20 links of worn stretched chain can be 11". I hope this helps.

Mr.Karl,

you might try and sharpen the 2 knives,1 on the plunger the other on the bale case,dull knives put quite a strain on the PTO. I always check the shear bolt that its tight each time I start the baler. next is needle timing then is the needle brake holding the needles untill its time to tie. Roller chain replacement could be called for too. good luck Tom N.E.Ga.

the only chain on this puppy is the ones that drive the pickup. all other parts are driven by gears/shafts.

Make sure your spring is working on the safety stop arm. And hay dogs are all working. Like the others have said maybe off just a bit. A nd don,t run this baler to fast will cause alot of problems. About a third to half throttle is fast enough. They will eat alot of hay at that speed run it faster it will cause you a lot of grief. I know been there done that.

You might try adjusting the brakes that hold the needles in place till time to tie. Could be a adjuustment on a threaded rod to lengthen or shorten the safety stop arm as well. Hopefully someone will be of help for ya. I would just have to really be able to look at it. I have run both New Holland and JOhn Deere square balers.

Have an old beat-up generic "bush hog." I could plan on replacing shear bolts several times a day, even when not striking any obvious hazards. They always broke just at where the threads end and the shank of the bolt starts. I've used all kinds of bolts, and all strengths - doesn't matter after an hour or two they're history. I've been buying in bulk from TSC! Ran short and got a couple from the local hardware store. Couldn't get the same length, so went 1/2 inch longer. This puts the base of threads right at edge of collar instead of at edge of driven shaft. Gone several days without breaking - Thinking of going to a softer bolt!

the bolts in my case are breaking because the safety stop is doing its job. however in normal operation of a square baler, it doesn't happen very often unless you are out of time or the knotting parts are out of adjustment. (you might go 1000 bales or more before it happens) or maybe you ran a block of wood or a fence post into the baler, which isn't related to the safety stop.

Your timing is just a little bit off yet. On my NH baler, ended up being the safety stop bar that was 'off' and needed to be timed (adjusted)..... .

Find yourself a Ford 532 baler man and ask him how sensitive needle timing is. I am willing to bet you are half a tooth off someplace after the packing fingers and it will take you half a day with the book to straighten it out. But when you do, you will want no other baler.

Can't really comment on any help but I do recall my uncle going thru a similar problem and trying to make an adjustment with the baler running. Appaently the baler timed out and a needle took a good chunk out of his middle finger. Take care and shut it down for adjustment and repair !!!!!
