Real-World Testing: Putting Sierra International 180209 Bearing Carrier Shim 0.001in to the Test
First Use Experience
I tested the Sierra International 180209 Bearing Carrier Shim 0.001in during a complete overhaul of my OMC stern drive, specifically targeting a persistent vibration issue. The installation required careful measurement and assessment of the existing bearing carrier clearance. This ensured that the 0.001″ shim would correct the gear mesh without over-tightening.
During the installation, I encountered varying levels of humidity and temperatures as I worked in my uncovered boat shed. The shim itself showed no signs of corrosion or warping, even after being exposed to the elements for short periods. This indicated good resistance to environmental factors.
The shim was very easy to use during the install. The precise dimensions of the Sierra International 180209 Bearing Carrier Shim 0.001in made it simple to install and stayed in place during the assembly process. I encountered no issues with fitment or interference with other components.
After the initial installation, the stern drive ran noticeably smoother during a brief test on the water. The vibration was significantly reduced, suggesting that the shim was effectively correcting the gear alignment.
Extended Use & Reliability
After several weeks of use, including multiple fishing trips and recreational boating, the Sierra International 180209 Bearing Carrier Shim 0.001in has continued to perform flawlessly. The stern drive remains smooth and vibration-free, indicating that the shim is holding its position and maintaining proper gear mesh. No unusual noises or performance degradation have been observed.
No signs of wear and tear are visible upon inspection during routine maintenance. The shim appears to be unaffected by prolonged exposure to saltwater and engine heat.
Maintenance of the shim itself is non-existent, as it’s a passive component within the stern drive assembly. I simply ensure that the surrounding components are properly lubricated and free of corrosion. This guarantees that the shim’s position is maintained and its function isn’t compromised.
The Sierra International 180209 Bearing Carrier Shim 0.001in significantly outperforms my previous attempts to address the vibration issue with generic shims. The precise fit and durable construction of the Sierra International shim have delivered a lasting solution, while the cheaper alternatives provided only temporary relief.
