Combines rotor belt wear and tear

Check the thrust bearing in the torque sensor portion of the variable diameter pulley. I had a 1460 which was eating belts. I got a service kit form the dealer, basically just a small needle bearing and special grease. The grease in the old bearing was dried out. This has been about 10 years ago, but most of the details here are correct. Essentially, your rotor drive is not smoothly shifting down as slugs or other higher loads occur.

Good call on the HD belt Pat. Needed one a few years ago myself. Parts man says, "Do you want the standard or the heavy duty beltIJ" I said "Whats the price differenceIJ" He says "About five bucks". "Then why do you even carry the standard beltIJ" I asked. He said, "We put 'em on used machines in the shop here." "Oh, well I'll never buy a used combine here then," I said. "Guess it'll have to be a new one!"

I am surprised that noboby mentioned about checking your rotor belt tension. You must insure that the alignment and tension are correct, or you will have premature wear. Always start with your top shieve with your rotor speed slowed right down. Once you get the top set then you adjust your torque sensing shieve. Your dealer will have the specific specs for your machine.
