273 baler

[Sberry]

I went thru a 273 as a first time baler mech. Hi learning curve. I found a vid on the knotter somewhere and slowing it down really helped to see what was going on
I had a couple faults last year and I'm the end broke a knotter bracket. Bent knife arm. We finally found a part, I still need a bill hook bushing. Looks the only way to get it is buy new. I flipped the roller for now.
I managed to find everything and had some help and line item install and got from manual
Got it all restacked and going to clean a little grease got a bit overdone.

Actually salvaged knotter arm. Took a couple tries to get it true and fit.

That's about what I did last winter. Tore the whole thing apart on the bench and cleaned everything. The bills had a lot of side play but I never knew what was normal. The flats on the pinions were worn pretty bad so I replaced all four. Got them from a dealer who was kind enough to break up two sets of cam/pinion kits and copied the instruction sheet for me. Then spent three or four long afternoons getting the stack back together with the proper clearances. Once I got it in the field it worked beautifully but it was quite a project.

I actually hired helper for the evening to do this so at least one of us could concentrate. Started on it about noon, by tghe time we fix he boogers was 8 but 2 of us.

I am going to get another bill hook tounge or make a roller, I actually reversed it. Also needs a new bearing follows in the drum,,, none of this will be an immediate stop the way it is. I went thru most of it 10 yrs or so ago,,, was thinking we might have missed a cotter pin in the original fix.

Did the same with the knotter on my 271. On the bench; much easier. Refer to my thread here on "rebuilding the NH 271". There might not be images posted yet!

I did go thru the thread. Was good.

Sberry,

If you can, see if you can get the original profile for the twine finger cam (circled in my attachment). Yours looks to have been worn down over the years.

We had a baler with this exact problem, and it causes "random mystery misses" for knots that can drive you mad, as the height of this cam determines the travel arc of the tips of the twine fingers. Also, check the ball that rolls on this cam for flat spots or being seized... which will cause this cam to wear prematurely.

When we noticed ours was worn, my son-in-law made a cardboard model of the actual profile... then built up the cam with our MIG welder and ground/polished it to match the original profile. I also put a new roller ball on the twine finger actuator; since the old one was frozen. Problem solved. At least that problem anyways. Knotters will always have another problem at some point.

Also? Duuuuuuuuuuuude... super envious of your shop.

I moved the machine from storage yesterday, sheet,should have looked in little tool box,,, more parts. Found Bill book assembly and pinion gear with less wear.

I will look for wear. It was trying fairly well. Occasional miss
We sharpened the twine cutter knife some. I baled some dry straw for neighbors, normally don't. I chop the green just before heads open and make mulch.
0nly 6 or 600 for me and actually broke it twice doing dry, must have been a thousand or so.
Timing is everything, I used to do 2x,, but hiring is a pain. I wanna do when I wanna do and can't wait till someone gets around to it.
