Mainshaft Oil Seals

1 products

Our mainshaft oil seals for Harley-Davidson — indexed under Transmission — are the specific oil seals around the mainshaft on Harley-Davidson transmissions from the early-Shovel FLT/FXR era. Iron Stable is run by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, and this very small section is supplied by James Gaskets. Typical fitment covers 1980–early-1984 FLT/Touring and FXR — the early FXR chassis-era Harley-Davidson transmissions. A fresh mainshaft seal keeps primary oil contained on any classic Harley-Davidson gearbox rebuild. Browse the full range below.
