I have a Troy-Bilt ("Storm 2840") snowblower (circ 2010). The model number is 31AH64Q4711 139966. The serial number is 1I 290B10416. The engine size is 277cc. I need a new belt cover. I believe the OEM part number is 731-07101. QUESTION: does your part number 631-05321 fit this machine?
For model number 31AH64Q4711
