Crankshaft Bearing A-8905 by EASTERN MOTORCYCLE PARTS, intended for replacement on Big Twins with 5-speed transmissions. This open bearing fits on the crankshaft and ensures the rotation of the engine train in Vintage/Classic and Touring motorcycle assemblies.
Designed for custom enthusiasts and long-distance trails, this bearing features the necessary functional dimensions for Big Twin models with a 5-speed gearbox. Ideal for engine servicing or restoration, it allows for a setup that meets original specifications without resorting to incompatible parts.
Common compatibility: Harley-Davidson FXWG 1340 Wide Glide (1981), FXS 1340 Low Rider (1981), and FXEF 1340 Fat Bob (1981). Before installation, check the references and the condition of the bearing surfaces (bearings, crankshaft end) to ensure a precise fit. For installation and alignment, consult a preparer or motorcycle mechanic if you are not equipped.
An essential part for anyone upgrading a Big Twin: replace a worn bearing to limit play and restore a clean and sharp engine performance on the road or during retro rides.
