What model of machine do you haveIJ thanks

I'm not sure which pulley(s) you're talking about. last year we had a bearing go out, causing the pulley to rub on a bracket. This was around 2:00 pm. Called around to Cat dealers. 130 miles east they had the bearings. 110 miles north the bracket, and they'd have to order the pulley, although it would have worked for the time being. The frusterating thing about that, had one dealer had all the parts I could make an overnight parts run, and have it fixed by 7 am, but I'm not driving town to town to piece my parts together. It didn't make sense to me to have one but not the other. Also, we found this year on an idler pulley, a bolt was missing also. It was the one on the bottom auger drive belt. Anyway, doesn't seem like a very reliable machine. 450 sep. hours only, lots of small problems like that. I think cause of that vibrating cylinder it shakes the machine to pieces. And I don't want to hear something must be out of balance....ya, the cylinder gets out of balance with dust. Something you don't get with New Holland Rotors

I am running a 480 cat The pulley I am describing is on the end of the impeller. As far as vibration shaking it apart. I think you have a lot better chance with a lexion because of the iron. That thing has got some meat on it. I used to run a rotor and they shake apart and have loose bolts also.

hhmmm, I'm not trying to argue with you, so don't take this wrong, but after running TR's all our lives, the first couple days in our 480 when we restart the sep. was mind boggling. SO much vibration everything shook. Our TR's never shake like that Cat does. After it gets dust to balance the cylinder out its fine. Shut it down for a few minutes, start it back up, and the dust just rolls out the back. The dust comes from behind the Rasp bars and throws it out of balance. Out TR's are VERY smooth, Honestly, if you plug your ears so you don't hear the sep. running, you can't tell if its engaged or not. The lexion shakes so bad it rattles the seat, headliner, monitor, sterring wheel....everything

does your 480 shack constantly or just when it builds up with dust if so the chopper could have some broken or chiped knives that will make it shake so bad you cant sit in the seat or your cylinder belt has sliped and it don;t take much like 3mm;s can;t see with human eye and that will make it shack if you feal vibration in the seat their is somthing not right

It only shakes for example right away in the morning, cause like I said, engaging it makes dust fall off from behind the rasp bars. Its then out of balance till the dust builds back up. We've had the cylinder out of the machine twice, and new belts put on. Chopper is fine, and usually fine after 30 minutes or so. Of course its worse the faster it goes.

Dust build-up in the threshing cylinder is common to all combines with an enclosed (corn type) threshing cylinder. Cleaning (blowing) them out is normal. One thing to try is placing 1-2 tennis balls inside the threshing cylinder, which will bounce around upon engagement and disengagement, knocking the debris (dust) loose so that is falls out during wind up_down during engage_disengage of the threshing (lexion APS) system. Referring to the 'ol "tricks-of-the-trade" are sometimes needed. And, using tennis balls is one for all conventional threshing combines.

Thanks Coors, probably won't need it anymore this year. We'll only be running in beans and corn, but I'll remember it for next year. Just not used to a cylinder machine I guess.
