yes, shaft, and hub and spacer. Of course you could weld up the current clutch or better yet shim it to the point of non slip and second answer only if yours 'failed'.
The main problem that we have is that the four 3_8" bolts that hold the clutch on keep breaking. Four times this fall to be exact. Huge argument going on, dealer and agco seem to be convinced that we are hitting the reverse before movement stops. Kinda hard when you aren't even reversing the chains. The second slip clutch has about 550 torque, and the front is full of springs. They want to put a new clutch on, and that is not the problem I want the clutch to stay attached to the shaft!
Do not the four bolts hold pulley on to the clutch and reverse sprocket is bolted to pulley so the only load on the 4 bolts is the rear chainIJ I put in updated shaft in my 62 and 72 this year,parts needed are;1 shaft,2 bearings,3 sprockets because shaft is bigger,1 star senor wheel,1 spacer,1 hub,1 keystock, 1 flatwasher and bolt from Agco.
That's weird. I believe original bolts are grade 8. Are you using grade 8IJ They are the same bolts in same location wheather you have slip clutch or not so I don't see how a solid drive will help. I would check to see if pulley is guided on center by shoulder. It should not be counting on the bolts to hold on center. Could it be pulley bore is to large or flange on clutch is to small to guide pulley on center. We just fill the clutch with springs when we have apart. Did you say you ever have feeder pluggingIJ Do you have rock sump kitIJ That's the system where you have to clean out daily. We have feeders running so smoothly now that we don't hardly need the reverser. Do you have the helical running across corner of feederIJ We find with a couple mods in cylinder area that load is reduced on feeder as well. It's funny how smooth these things will run in the toughest of conditions if the straw is flowing smoothly.
We always replaced bolts with grade 8. I do not have a rock sump kit, and the only time that I have feeding problems is when it tries to ingest something it shouldn't like a rock. I have the helical across the corner of the feeder and the rotor is hypered. Smooth running in some pretty tough conditions. The agco guy that calls on our dealer came out, and blamed the whole problem on the rotor not being stock. He seems to think that if I put those darn reverse bars on the problem will go away. As far as I can tell everything looks normal, tight and in line with the pulley. This is the fourth gleaner rotary we have owned and the only one that has ever done this.
We'll I hope I don't get that AGCO guy out to troubleshoot one of my problems. That's crazy. Anyway I have to think your problem started with loose bolts. I would believe that pulley got to wobbling on slip clutch hub. This likely wore the counterbore that supports pulley. I would take the belt loose then remove the bolts. Try move pulley up and down to see if there is any movement at all. If there is the pulley counterbore is worn. We have alot of more powerfull machines running alot more straw threw than you likely do and no problems at all there. Hope you find problem there. Good luck
