Combines 52 WITH CROOKED FEEDERCHAIN

We had the same problem with our R-52 last year. It is apparently a very common problem according to the dealership. I thought ours was off half a link too. They came out and simply loosened the feeder chain a bit. He then put a bolt down thru the chain on one side or the other (depending on which side is off) right behind the front feeder roller and pulled one of the belts along the feederhouse to rotate the feeder chain. The bolt held one side from turning while the other side jumped a cog and the chain was straight again. I too had checked set screws, sprockets and everything else. But now I know how to do it myself and save a hundred dollars or so for a farm call. Don't keep running it that way as it will cost more to replace a worn feeder chain, or worse, cause it to break if it jumps another cog and go thru the machine.

I have always used a 9_16 deep well socket and place it in the valley between 2 sprocket teeth. Take hold of feederhouse belt and roll backwards. Spocket will come out the bottom and chain will be lined up again. Helps if you lower feederhouse as far as you can before starting process. Kelly

cant remember for sure(it was a few years ago)but we put new sprockets on our n6 and i think if you put a sprocket on the shaft backwards it will be out half a tooth!!!

Make sure the sprocket set screws are all on the same plane on the hex shaft. If not sprocket teeth will not be timed properly.

Kelly, I hope you have a string tied onto that socket. Otherwise you will be in the header digging for it at the front of the feederhouse. Personally, I use a 3_4 or 15_16 box end wrench and place the box end over the tooth and roll backward. Also, have string tied to wrench.

SET SCREWS ARE ON SAME PlANE AND BOTH ARE ON THE INSIDE BUT DO NOT lINE UP ON SHAFT. ONE IS IN MIDDlE OF THE FlAT SPOT AND THE OTHER IS TO ONE SIDE TOOK A STRAIGHT EDGE FROM THAT FlAT PlATE IN FRONT OF SPROCKETS AND lADDER SIDElINES UP ON TOP OF A TOOTH ON SPROCKET AND OTHER SIDE MISSES AND ENDS UP IN THE BOTTOM OF A TOOTH
