Storage, trim and cosmetic hardware
Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.
Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.
Parts in this group on 31AM5CSF799: 68405203A4044 (Snowblower Auger Housing (Craftsman Red)), 749057010637 (MTD Snowblower Lower Handle (Powder Black)), 790005340637 (Bearing Housing), 749056710637 (MTD Snowblower Upper Handle, Left (Powder Black)), 749056720637 (MTD Snowblower Upper Handle, Right (Powder Black)), 75006087 (SPACER), 75306437 (Snowblower Handle Panel), 777D21063 (Snowblower Handle Panel Craftsman Decal), 79000075A (Snowblower Impeller Shaft Bearing Housing), 777I22341 (Snowblower Panel Decal), 684041070716 (Deck Housing (Yellow)), 79000503 (Snowblower Chute Bracket), 79000075B (MTD Snowblower Impeller Shaft Bearing Housing), 790003164044 (MTD Snowblower Frame Cover), 9200284 (Snowblower Wing Knob).
Drive system (belts, pulleys, motors)
Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.
Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.
Parts in this group on 31AM5CSF799: 63105322 (Cover Belt Assembly), OEM75404050 (Snowblower Auger Drive Belt), 256963 (MTD Snowblower Auger Drive Belt), 95404050A (MTD Snowblower Auger Drive Belt, 1/2 x 35-1/4-in), 95404260 (Lawn & Garden Equipment Belt).
Before you buy
Match 31AM5CSF799 exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.
How to confirm this is your model
Check inside a door opening, on a back or side panel, or behind a removable panel or drawer for a label printed with the model and serial number. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.
Still not sure?
Use the model lookup tool to search by model or part number, or start from the symptom your appliance is showing.
