I'm on my third belt I have 571 miles on it. I love the chassis its just awsome. But I can't have a sled that blows belts like this...I will not modify anything on this sled until this major problem is fixed. But what if Cat will not fix the 2012's? Soon the 2013's will be out. Someone would be taking a 12,000.00 plus gamble buying a 2013 M800 it may eat belts just as bad. I would not recommed anyone buy one until this is fixed. You might get lucky and get one that doesnt munch belts. What is different with the 1100T they do not seem to be eating belts? Should I start the process of returning the sled under my states lemon law? Should I lawyer up and see what my option are both of these option will cost even more money. If you are having belt problems are you getting new belts covered under warranty or are they making you buy them? My dealer has not given me an answer if it will be covered. I keep reading that Cat is aware of the isssue and they are working on a fix...Are you Cat? If cat fixes the problem I would recommed this sled to others and will buy more sleds from you in the future as well as other products. I just don't know if it will be fixed.
