Combines what to look for in a used 9600IJ

Take some metric tools with you when you look at it and take some access panels off to get a good look at the inside of the machine. Take the access panel off at the very top of the feederhouse, just below the cab, this will give you a good front view into the cylinder and concave, then you can check the condition of the bars, concave and beater. Also check the cylinder heads (spider),the hubs that the cylinder shaft runs through and the bars bolt to it. 9600's are well known for cracking these, especially the ones that are keyed to the cylinder shaft. The other spiders are just "floaters", but they can crack too. Take a hammer and rap each one on the side to check for cracks. Also, on each side of the combine in the general area of the concave thier are two small access windows that let you see into the front and rear of the concave. When looking through the windows you should be able to see the cross section of the concave cross bars, if the leading edges of the concave cross bars are rounded it is time for a new concave. Another thing to check through the access windows is line up the highest part of a cylinder bar with one of the concave cross bars. If you do this the high spot of the cylinder bar should be at the same point of the concave cross bar on each side of the concave. What you are checking here is if the cylinder has a spiral to it (Bars do not run parallel to concave). 9600's are known to have this problem and if it is spiralled it is more than likely one of the cylinder spiders that is twisted not the cylinder shaft itself. Good luck and check it over well.

Also check if the straw walker bearings have been upgraded to the newer white metal type, check how much wear is on the plastic rub plates between each walker, and if it has a chopper on it get up in the engine bay an open the walker inspection door and see if there is any daylight coming through the body panel from the left hand side, cause this is the starting point for the rear hood to part company with the rest of the machine.Even if this one hasnt a chopper, this might help other 9600_9610 people to check their own machines, yes even the tens do it. Another thing would be the bearings on the seive box drive, the ecentric ones. They have been known to have been replaced every 1200 hours... hope this may be of some help.. BOSS 351
