336 baler questions

I worked on and owned JD sq balers for years. They have no history of crankshaft brg failure such as you stated. As far as needle breakage if the plungerhead stop had been functional on your 336 "no needles would have gotten broken" from needles being out of time with the plungerhead. The plungerhead stop would have saved the needles. I'm curious can you scan the incorrect needle timing instructions in the operators manual and post that incorrect info on this site???

Tx Jim;

When I worked over my "new-to-me" 336 baler - I seriously considered replacing the plungerhead stop. It had been beaten and slammed nearly into submission!

Whoever owned the machine before had problems enough with the knotter assemblies (worn out pinion gears) that the thing must have been jumping out of time and bringing the plunger to a full stop - pronto!

Probably should really get a new/used one as the latching edge is just about shaved off and might not really stop the plunger under full power.

But, she's been working so good the last 2 years - I hate to do anything besides sharpen the twine knives and clean up the stationary knives on the plungerhead and a little grease!

The normal reason the plunger head stop(parts key #1) gets worn from contacting crank arm isn't baler getting out of time but the stretching of the angle of the lever(I call it the boomerang parts key #12) from the needle frame slamming into it when needle frame returns to home position. The stretching of the lever angle allows the stop to start clipping the crank arm on every stroke of the plunger head. Back when I worked for a JD dealer multiple numbers of those levers were replaced for the reason I described.

Well... that's a good "nugget" of information! Thanks! :thumbsup:

(I looked at that plungerstop -- and... man, I was glad I wasn't in the field when that baler did whatever it did to cause that!! )

I'll give you another "nugget of sq baler info" if you'll send me an "Alaskan Gold nugget"!!!!!!!!!
Seriously the stretching of the angle on the lever can cause the lever to bind on the pivot bolt bushing therefore rendering the PH stop inoperable although mechanism will appear operable.

Hmm... every season, I pull the baler into the shop and go over everything and then hand bale a couple of bales with it before hitting the field. I fire the baler up - "dry" for a few minutes at 150 rpm or so and look it over - then actually bale with it a 540rpm.

Have to admit - I've never actually watched the plunger arm cycle past the stop mechanism.

I will this year... Thanks.

And, I'll be lookin' very closely at that "boomerang" lever, too.

To see anything but fast moving PH stop you'll have to cycle tying mechanism slower than 540 rpm pto speed. At 540 rpm(80 strokes per minute) PH stop will be a BLUR while its moving.

Very true... that's why I just watch everything workin' at a pretty slow rpm! Then when it's apparent that all systems are a go - I'll fire it up and bale a couple of bales at full rpm's.

Hello! Prompt that can such be. The problem in that that tears the right side of a bale, or doesn't fasten. You don't know in what there can be a problem?

Twine or wire tie?
