IH 430 baler

[Furjam6]

I m just starting out baling my own hay and picked up an IH 430 baler. Have had some issues but worked through them and hooked up to run and snapped the shear bolt. It seems to be the plunger getting jammed. But it gets stuck when the arm is about to turn over going forward and backwards. Just wondering if anyone has any ideas before I pull the plunger if it could be anything else.

Is your plunger stop for the needles down or up in the chamber so the plunger can't travel full travel? Don't know much about balers .

Needles are going up. The knife on the plunger makes it about halfway before jamming.

I can think of two likely possibilities: First is bad bearings or side to side adjustment in the plungerhead allowing it to get cocked sideways, or, rust under the rails that the plungerhead rides on. Turning it by hand will reveal where your problem is.

The wrist pin on the plunger could be clapped out or the wood blocks are swollen & are binding on a constriction. Look for dents & dings in the area
that the plunger moves in. Check the side rails & guides, too. Also check to make sure it isn't hitting the stop dog.

Most likely:

On the left side of the baler you have a knotter brake plate - looks like a small disc brake on a car, there are two brake pads (shoes) on the sides of the disc that grip this with enough force to
keep the needles up in the neutral position. If these pads are worn out (or even missing) the cradle that the needles are bolted to will start to settle and it trips the plunger stop - this keeps the
plunger from striking and bending/breaking the needles. Easy way to check - jerk the cradle up tight as you can to the bottem of the baler and see if you can roll the baler over without the stops
preventing the plunger from its entire range of motion. My baler had this issue especially in rough ground that would cause the cradle to settle until it tripped the plunger stop shearing the flywheel
shear pin.

You nailed it on the head. The baler had been sitting for 2 or 3 years the cradle was alittle sticky and wasn t moving all the way back up to press the plunger stop rod. Got it up and running today. Thank you for your time to post.
