  • Inspect the countershaft area for oil leakage, scoring, or wear before beginning any seal replacement work.
  • Clean the countershaft housing and surrounding surfaces thoroughly before fitting new seals to prevent contamination and ensure a proper seat.
  • Lubricate new seals lightly with clean engine oil or assembly grease on the sealing lip before installation — never fit seals dry.
  • Use the correct seal driver or a suitable socket to press seals squarely into their bore; avoid cocking the seal during installation.
  • After reassembly, torque the countershaft nut to the specification listed in your model's factory service manual.
  • Check for oil weeping around the countershaft after the first short ride and again after a normal-length ride before returning to regular use.
  • Dispose of removed seals and any contaminated oil rags in accordance with local environmental regulations.
  • Store any unused kit components in a cool, dry place away from petroleum solvents, ozone sources, and direct sunlight to preserve seal integrity.
