Looking for the Double Gear inside the final drive housing looks like part number 8M8111. This is the one that’s stepped down from the 47teeth to the 12 teeth. Anybody had any luck finding an aftermarket source for these gears or will I have to find a salvage machine?

Hi DWC7, The 8M3111 gear was superseded by 2S3947 (same teeth and bearings) starting with 47A2431. I think it is still available, the sprocket hub 5M5037 is NOT so be careful pressing the sprocket.

Dana at Florin Tractor Parts is friendly and knowledgeable and their prices are reasonable. I have bought "can't be found" parts from them, 1-800-223-9916 in Sacramento, CA.
