Combines Feeder House Drum

Is it a closed feederhouse drum or openIJ Where did it break exactlyIJ

Vikes, after 40 years of service, the welds are still holding well on the 'ol 510.

It is a closed durm. It broke where one of the sections is welded to a section where the roller chain comes into contact with the drum. Approximately one third of the way across from the Drivers (left) side of the machine. The replacement part is closed also and is a new designe with a couple of rings attached to keep the feeder house slats from bending. I have some reservations about the rings making the whole assembly more suseptable to rock damage. But that is another story.

I have never heard of the drum breaking before, was it rock damageIJ I have tried the rings on the feederhouse, they work very well. They keep the slats nice and straight.

I though you said you had a super 92

I did, but I figured that I needed to invest into more "modern" equipment. Besides, the dynamics of the Super 92 are such that yield monitoring and mapping are prohibited. The advancments made to the 510, over the Super 92, have led to a extraordinary reduction in noise and vibration, supporting the use of yield monitoring and mapping with GPS. Besides, it has a preperation pan too. I rekon my next investment will be to install custom rubber capped 6-roller Massey tracks.

I will not say that rock damage did not have anything to do with the drum failing...but. The main reason for failure seems to be welds that did not penetrait on one side or the other. On the replacement drum there are gaps of about one sixteenth inch between the welded parts thus making for some very bad looking welds. So far we have done about 800 acres of corn and the welds etc. are holding (no visiable cracks, etc.) As for the rings my concern is that there is no "give" in this system. The only slipclutch protection comes from the one that also runs the head. If I remember correctly that is set to slip at 600 ft_lb of torque. As we have a bunch of rocks I would preferr to have a seperate slipclutch with a lower slip torque.

The slip clutch for the feederhouse is not integrated with the head's slip clutch. It is separate. The feederhouse slip clutch is on the hub of the large pulley on the left hand side of the feederhouse. If this clutch slips, you are still driving your head. One more thing, I now remember, on the first drum we had in our combine that we did cracks some welds out. The latest version I have though is working fine.

Yor are correct about the slip clutch. I went out and looked last night. Here is a picture of what I am complaining about. I guess I am goint to have to learn alot more about internet explorer etc. in order to get a picture on this part of the Combine Talk Show. I wonder if it is possiable. They probably want to keep file size down.

The easiest way to do it if you don't mind cutting your field tracker plate is to cut out a knotch in each side so it will allow the drum arms to pass through. Only other way is to remove the entire plate which is time consuming. I have done it both ways and anymore I prefer to cut up the plate.
