2.25" Propeller Extension for O-360 with 1/2" Bolts
Deluxe Extension for Wood Propellers
This series of propeller extensions are specifically designed for all currently manufactured RV kit aircraft cowls. The extension length is 2 ¼" and it is 7" in diameter. The design incorporates dual 6 bolt patterns, one pattern for the extension/crankshaft bolts and one pattern for the propeller/extension bolts. The purchaser should select the extension based on the bolt diameter in the crankshaft lugs in his engine.
All of these extensions come with the bolts and washers for installation on the engine, but not the propeller bolts. The lugs provided for the propeller bolts are threaded so no nuts are required. The builder will choose the prop bolts and washers based on the thickness of their wood propeller hub.
