Replacement gear for PFM (built by United) HO Shay including the B-2, B-3, and Pacific Coast shay. Also fits the NWSL Willamette engine. Provides better life than the original brass gear. Note: You MUST use this gear with the 12-tooth gear already in the engine. You CANNOT mate two of these gears to form a 90 degree angle (for say your own project.). Bore is 2.4mm, same as the factory brass gear. Sold each.

The 12T gear that works with this gear is #124-6.
