328 John Deere baler repair

I picked up a used 328 baler earlier this year. It has worked flawlessly for three cuttings and will digest about any amount or condition of hay I feed it to bale. Never a banana bale and the knotter only missed once on one side of a single bale. Unfortunately a 'cheater' bar was left unnoticed in the filed after a repair in the filed during the last hay haul. It must have got picked up when raking the hay. A very distinct clunk and bang that killed the tractor after the takeup picked up the bar and fed it into the bale chamber. The bar actually sheared. I dug out the culprit bar and attempted to finish the last row of baling. Now the baler will catch at normal feed rate. If you go slow and restrict how much goes in the takeup, then it will bale normally. If you go at a normal speed it will bale and eventually just catch and stop. One thing I notice is the flywheel has a tick while spinning free and the drive line is not spinning. Tick Tick as it spins, I don't remember a tick in the flywheel just spinning free when the PTO drive line is not rotating. So the big question is before I tear into it, are there certain parts or known breaking points I should investigate. It looks like the tick is trying to push that arm a little after the gearbox on the flywheel, not sure what you call that arm but it ultimately drives the plunger. Does your 328 have a tick also is it possible I bent something in that gearbox? Why is there not a shear pin?

JD 328 baler has a flywheel shear bolt(key 11). JD part # for shear bolt is BP13931

i would check the plunger and knife. Very likely deformed or took a chunk out of the plunger knife or stationary knife. Its hitting each time the plunger goes past.

As Jim said shear bolt has broken and that is what it is for to protect the baler

Tick may be the dogs in the over running clutch. Flywheel is driving the baler and powerline is standing still. It would have been there before the incident.

Other tick may be plungerhead knife to stationary knife. You should really look it over well before using more.

Tx jim haswhat you need,its a bolt that shears often.go to your friendly jd dealer buy several and the nuts.get jd made shear bolts for good reason too. Keep running it like that the clutch disc plates will need replacing.look n make sure you didnt loose the bushing too

Will they run at all with a broken shear pin ?

Your knives are likely gouged and catching as they pass each other. And if it snuffed the tractor your slip clutch is either too tight or rusted up it should have slipped and not stalled the tractor.

Yes, but they will make a ticking noise as he has. I have 3 of them. A 336, 338 and a 346.

Yes JD sq baler will bale hay with shear bolt sheared if slip clutch is adjusted too tight or if SC is rusted stuck.

That?s interesting to know . There are almost no
little balers around any more and even where there
was I think there was only one John Deere. I baled
500,00 bales with two different 348 With a thrower
on the back but one was 1/64 and 1/16 scale
actually wore the big one plumb out
