4th Gear Andrews (manufacturer ref. 204280)
Robust replacement for the 4th gear main sprocket, designed for Vintage/Classic and Touring motorcycles. This Andrews sprocket retains the original dimensions while incorporating targeted improvements: widened drive grooves and steeper entry ramps for sharper 3ā4 shifts. The new groove profile allows for the accommodation of an O-ring on 4th chain-driven sprockets, facilitating the sealing of the drivetrain.
Particularly suitable for Harley-Davidson models equipped with chain-driven gearboxes (common examples: FXWG 1340 Wide Glide 1986, FXST 1340 Softail 1985, FXSB 1340 Low Rider 1985). Replacement sprocket ready to be fitted during a gearbox overhaul or primary drive maintenance.
Workshop tip: check engagement play and the condition of other sprockets and seals before installation to ensure smooth operation of the gearbox. Sold individually.
