Product Details

The Sierra 18-9870 is a specialized installation tool designed to properly seat the aluminum retaining sleeve into the U-joint bellows on MerCruiser sterndrive units. This essential tool ensures proper alignment and prevents damage during bellows installation and replacement procedures.

Key Features:

  • Installs aluminum retaining sleeve evenly into bellows groove without twisting or misalignment
  • Compatible with MerCruiser Alpha One Gen II, Bravo, and Blackhawk drive units
  • Prevents damage to the retainer ring that can occur with improvised installation methods
  • Ensures proper seal to avoid leaks and premature bellows wear
  • Simplifies a complex installation step for both DIY mechanics and professionals
