We have been looking for a 9600-9610 to purchase. Some of them have cracks in the sides just above the rear straw walker crank. What causes this? Can it be fixed? Or do we need to continue running as fast as we can when we see these problems. Also, as I do not have much experiance in what to be looking out for in these combines, (or any other for that matter) any, and all help would be greatly appreciated. I know with all the combine knowledge on this site, someone will know what I am talking about.

I believe you are refering to the vibration cracks around the straw chopper drive supports on the left side. This is very common, especially on machines with fine cut choppers. There is an update for the support that runs straight up from the outer end of the chopper jackshaft. DTAC solution #43672. Your dealer can print it out for you or maybe Tom has time. The rest of the cracks can just be welded. Be sure that the chopper runs smoothly on any combine you purchase to prevent further damage. Vibrations are usually caused by an unbalanced rotor but could be due to damaged belts. Also check the alignment of the chopper drives.

It's threads like this that are really valuable (great question to a problem more than a few will encounter, and a well-stated answer). And all done without making a remark about the machine's color or calling anyone a ****wad. LOL. Thanks to both of you.

Thanks for the information, greentech. Have another one for all of you. We looked at a 9650 this morning and it had cracks on the right side of the combine (and forgive me, because my combine knowledge is lacking) roughly where the cylinder sits, kind of above some of the bigger pulleys. The salesman said it was just a stress fracture. But I say a stress fracture from what??? Dad seems to think this is a pretty good combine but I think otherwise, there was just something not right about it. Nearly every bearing on the right side had been changed and some had to be beefed up via some bubblegum welding. Made me think someone may have tourqued the ol' girl at some time or another. I have read on here that once a combine is warped up in some way they may never be the same. Thanks, again.

SIDE SHEET CRACKS DUE TO EXCESSIVE VIBRATION CAUSED BY MISALIGNED DRIVE SHEAVES OR LOOSE DRIVE BELT. VIBRATION IS TRANSFERRED INTO THE SUPPORT ROD AND MOUNTING BRACKET CAUSING THE SIDE SHEET TO CRACK OR THE WELD TO BREAK ON MOUNTING BRACKET.

Thanks, Tom Turner, There is a wealth of combine knowledge in the people on this site. When we get our combine I will install this kit. Thank all of you very much.
