Their <a href="/7570-sierra-engine-gasket-set-5404">engine gasket sets</a> provide critical sealing solutions for inboard and outboard motors, while their <a href="/7570-sierra-engine-complete-assembly-15341">engine complete assemblies</a> offer comprehensive replacement options for major overhauls. Each component undergoes rigorous testing to ensure reliability in demanding marine conditions, from corrosion resistance to temperature cycling performance.</p><h3>Instrumentation and Monitoring Systems</h3><p>Accurate instrumentation is essential for boat operators to monitor engine health and prevent costly breakdowns on the water. Sierra's comprehensive line of <a href="/7570-sierra-gauges-200483">gauges</a> includes everything from fuel pressure and temperature indicators to voltmeters and trim gauges, all designed with marine-grade materials that withstand vibration, moisture, and UV exposure.

The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture. Their warranty coverage extends beyond simple part replacement—it includes shop labor, haul-out fees, towing charges, and related incidental costs should a warrantied part fail. This comprehensive protection reflects the company's confidence in their manufacturing processes and quality control standards.

Product Details

The Sierra 118-79820-2 Gimbal Bearing Puller is a specialized marine tool designed to safely and effectively remove gimbal bearings from stern drive transom assemblies. This professional-grade tool is engineered to extract even the most stubborn or seized gimbal bearings from Mercruiser, OMC, and Volvo Penta sterndrive units.

Key Features:

  • Features expanding jaws that interface with the gimbal bearing inner race for secure extraction
  • Heavy-duty construction with threaded shaft assembly and large extraction nut for controlled pulling force
  • Includes backing plate that seats flat against the gimbal housing during removal
  • Compatible with Mercruiser Alpha, Bravo, OMC Cobra, and Volvo Penta SX sterndrives
  • Interchangeable with Mallory 9-79820

How It Works: The tool's expanding jaws are inserted through the gimbal bearing in the closed position, then rotated clockwise to engage the bearing's inner race. Once properly seated, the large extraction nut is turned while securing the shaft assembly with a wrench, gradually pulling the bearing from the gimbal housing.

Professional Notes: Lubricate all threads and bearings before use. If excessive resistance is encountered during extraction, the bearing may be severely seized—continuing to force the tool in this situation may cause damage. In such cases, cleaning corrosion from the bearing and housing or applying penetrating oil may be necessary before attempting removal.

Sierra marine products are manufactured to meet or exceed OEM specifications, providing reliable performance for professional mechanics and serious DIY enthusiasts working on stern drive maintenance and repair.
