IH 47 baler problems

[Bcarl9207]

I started baking yesterday and of coarse I was fighting knots but it eventually would not engage the knotter mechanism. The trip arm activates but the knotters wont engage. I'm at a loss and cant seem to see or even read where I'm missing what drives the assembly. The wierd thing is that I can manually trip the trip and move the needles up and back the the trip resets and I can rotate the pto by hand and it will all engage and do it's full range of motion. Any help would be appreciated.

Sounds like the pawl spring in the clutch is
disconnected or broken. Your description is a little
confusing but it seems like you are turning the
knotter shaft first by raising the needles, which
would cause the pawl to drop into engagement by
gravity after the knotter clutch made a 1/2
revolution... now it will finish tying by turning the
PTO until it reaches the park position.
Look at your knotter clutch. There should be a
finger projecting from the clutch housing, held in
position by the metering/trip mechanism, when it is
in the park position. With the tractor off, turn the
bale metering wheel until the mechanism trips the
clutch. As the lever slides off the finger, the finger
should snap into place, engaging the clutch. If
nothing happens, grip it and move it and see if there
is any spring tension.

When it trips the knotter barrels on the main shaft turn just slightly. But no further movement happens. Where is the clutch at? I dont see any springs or clutch discs. Do I have to take the knotters apart to see it?

The clutch is on the knotter shaft just outside the bale chamber. Follow the linkage from the metering wheel and it will lead right to it. There are no clutch discs, its simply a round housing with flutes on the inside diameter; the pawl drops into one of these flutes when the metering linkage releases it , and it is supposed to stay engaged for one full revolution, when it again comes in contact with the metering linkage, which disengages the clutch. If you go to CNH online parts, you may be able to see a parts list for it.

When you are looking at the knotters from the left (chamber) side of the baler, the knotter drive mechanism is behind the cam for the right knotter.
It's the gear you see sticking out behind the cam. Yes, the whole knotter stack comes out of there to reach it. Most likely the trip dog roller is
shot & not catching when it should, by the sound of it.

To get to the trip clutch:

You have to disconnect the shaft that drops down to the needle yoke, unbolt the knotter frames, unbolt the packer relief anchor support from the
outer knotter shaft bearing support, then you should be able to grab it by the bearing support & pull it toward you. That should get the assembly
off. Then you'll see the trip mechanism & figure out if it's worn or not. It's also possible it's packed with crud &/or the spring is tired.

Also..... BE SURE TO KEEP EVERYTHING IN ORDER & NOTE HOW THINGS ARE ADJUSTED. Some of that might change after repairs, some things don't. It can be
an adventure putting new parts in pooped out equipment that doesn't want to adjust to the book or the previous worn out settings.

My brother had the same problem a few years ago when he bought an IH 435 baler same knotter trip, from a neighbor that had been parked in a
shed for several years. We fixed it by spraying our favourite penetrating oil in and around the knotter trip mechanism and let it soak and reapply,
did a few manual tests and then it worked.
Good luck with your baler.

I got the knotters pulled off today and found the mechanism to all be in tact. Its binding on the pin that the assembly hinges on. I can work it and it will free up, reinstall the knotter assembly and by the time I cycle it twice its stuck again. I keep hoping I find a sweet spot. Both springs are not broken and the roller is in good shape.
