Transmission Gaskets Speedo Hole

4 products

Our range of Transmission Gaskets Speedo Hole for Harley-Davidson covers the small sealing gaskets used around the speedometer drive hole on 1936-1984 4-speed Big Twin Harley-Davidson transmissions with transmission-driven speedometers. Iron City Motorcycles in Leeds is an authorised Harley-Davidson dealer, and speedo hole gaskets are precision small seals that stop transmission oil weeping around the speedometer drive on a vintage Harley-Davidson, where a failed seal shows up as oil running down the left side of the gearbox. You will find Cometic's material-matched sealing rings and James Gaskets' engineered rubber and fibre seals, both sized to the original factory dimensions used across decades of Harley-Davidson 4-speed Big Twin engineering. Whether you are restoring a Panhead, refreshing a Shovelhead 4-speed or completing a vintage FL rebuild, the correct speedo hole gasket is here. Browse the full range below.
