I'm not sure where I read it but thanks for the update! This is great information msafi65. There should be a sticky thread at the top of the forum just for part numbers and cross reference info on these machines. It's needed now more than ever with the current parts situation. I'll have to go back and check my factory belts, I could have sworn they were the 018033 belts that you said match the 1092M3 belts I bought but I'll hazard a guess that I made a mistake and they are most likely 018039
