John Deere 336 Square Baler - Twine Tie

Dad and I decided to square bale some first cutting hay (one of the best clover stands I've ever seen in a first cutting). The baler did fine for the first 75 bales or so, but then it started sometimes making an awful banging noise on every stroke after the knotters would cycle. Got to looking, and the needles weren't fully returning "home" after entering the baling chamber. It didn't happen every time.

Dad got the book out and studied a bit. He decided he needed to adjust the Needle Lift Link, following the specs in the owner's manual (pic is crooked, sorry!):



Ran the baler, it seemed to do fine for another 40 bales or so, then started doing it again. Still not every bale, but maybe 40% of the time after the knotters ran their cycle.

Does anyone have a suggestion as to what could be the culprit here? Dad thinks it may be this guy:



In any case, I'm a bit leary of tearing into this baler too much, as I don't know much about knotters and timing and all that. And the whole thing runs like a top other than this--making consistent, tight, uniform bales.

Any suggestions would be greatly appreciated!

Are you SURE the needles aren't actually retracting all the way, then moving back into harm's way because the "needle brake" pads are worn out, or simply need to be set tighter? The operator's manual covers their setting, IMHO. Needle brake pads are #13 in the parts drawing below.

Check to be sure the spring (#6)is intact and there's no obvious damage in the "dog clutch" area you have circled in blue.



Check that bolts, key# 23 and 24 are not loose, badly worn, or partially sheared.

Now that you mention it, the needle frame may have fully retracted, then kind of "settled" back into "harm's way."

Does this brake sit right next to the knotters? I have the manual here with me, but the machine is not around.

The needle brake is on the RH end of the knotter shaft, the needle lift is at the LH end of the same shaft.

In your pic, that trip dog should be in the position shown. If it rides a bit high or low, the fix is moving the trip are slightly forward or reverse. If
your knotters are cycling, there is nothing wrong with the trip dog spring and if it were, it has nothing to do with your needles returning to home.

What it sounds like is happening is your knotter and needles are cycling as they should, however your knotter brake is not holding the needle
frame in the home position and it droops, causing the plunger stop to engage just enough to give you a bang noise, but not enough to stop the
plunger and shear the flywheel bolt.

Sometimes with a needle carrage brake, it appears to hold, but as you make your way around the field, between the baler plunger slamming
the baler forward and backwards, bumpy fields will jolt the needle carriage down/out of position, causing the plunger stop to engage as I
described above.

I don?t have my manual in front of me, but I think there is a spring scale tension the needle carriage brake should be set. This is an easy fix and
I think will solve your problem. I would not screw around with the trip dog unless your knotters aren?t cycling.

336 IMHO is a fine baler - one of the best ever made by anyone.

Good luck,
Bill

As was said. Check the brake. If it has been sitting a while they could have spit the lining out.

I also think needle brake isn't holding needle frame in home position.

The awful banging noise is probably the plunger head safety stop hitting the crank arm. It should hit solidly and
break the shear pin on the flywheel. If it is not, you need to adjust that mechanism or you will BALE THE NEEDLES!
That is $$$$.

As stated below the needle brake is still the likely culprit, but plunger head stop needs adjusting too!

I would say the plunger safety stop adjustment should be CHECKED, but may be just fine.

If the needle brake is slipping and the needle frame is dropping just enough for the safety stop to begin to rise, the plunger will rattle past it without catching.

Brake disc is to the left of knotters in the photo.

Finger Lakes Equipment in NY rebuilds JD balers. They will tell you what is wrong and how to fix it.

I'm going to 2nd Bob's statement that the needle brake is on RH end of knotter shaft on a 336 & disagree with ArleninOr statement that it's on LH side. Needle brake was later moved to LH side on baler models such as a 347
