I am updating 1470 and installing the kit CaseIH sells so that you can adjust the pinch point on the concaves, such as the 1660 had. There are no instructions in the kit. These are the brackets that are on the right side of the machine that the pipe for the concaves mounts into. The original hangers used 3 half inch bolts to secure. The new brackets use 5 five eights bolts. There are two holes that match the original holes. I assume that you drill them to the new size and then use the brackets as a template to locate the other three holes. Is that correct? My local combine guru is gone for a few days and was hoping to get this done over the weekend. Does not look like much fun getting to the back bracket to drill the holes. Would pulling the return tube that goes into the rotor cage help any. I have the sieves out for other work but still really beyond reach going in from the back. I have the old brackets out. Installing new concaves and it was suggested that this kit be installed at the same time. The kit is pictured on page 39 of the 2005/2006 product support kits book. Thanks for any help. Dennis

OK I got the adjuster kit mostly installed. While doing so I noticed the rotor seemed a little out of balance. So I spent today blowing out all the build up under the bars. It is a little out of balance. I can not hear anything inside the drum not did I find any holes. It stops in the same spot every time. The seam is at about 4 o'clock looking into the rear of the machine when the rotor stops. Anyone ever balance a rotor while in the machine? Or would it be better to pull the rotor. Previous owner said he had the rotor out about 1000 hours ago to put in a new cage. He is pretty sure he put in new bolts and bushing at the drive end at that time.

Learned that the supports would come out of the machine after got all the holes drilled! Anyway was talking to a neighbor who has done this mode several years ago. He suggested updating to solid shafts to hang the concaves on and the pipe going across the top to support the pipes in the middle. This machine still has support bolted to the cage, 1/2 inch redi rod coming down to the hanger pipes, and the pipe hangers. Is it worth the doing while I am in there? Thanks Dennis

are yor pipes bent? Here we always bend the pipes so the shaft kit is well worth it but I think its the tough conditions and the wads that bend the concaves and if your condions are not like ours the pipes would be fine

The lower pipe seemed straight enough. The upper pipe that clamps the concaves down was bent some. Not sure why that would be. I have only had the machine two years and so far have been lucky and not slugged it. I suppose the day will come. Will check into prices some more I guess. Was noticing that several screw heads in the cone area are getting badly worn so I better do some closer inspection of that in the next few days. How do you judge when the elephant ears need replaced? Learning more everyday as I work on this machine.
