Let’s Dive into Sierra International 1802067 Gear Position Shim 0.015in
The Sierra International 1802067 Gear Position Shim 0.015in is a seemingly insignificant, yet critically important component for maintaining the proper operation of many OMC stern drive units. Made by Sierra International, these shims ensure precise gear engagement, preventing premature wear and tear. At a price point of only $7.58, this tiny piece of metal can save you from potentially catastrophic and expensive repairs down the line, so it’s something to keep an eye on if you work on your own marine engines.
My own need for this shim stemmed from a frustrating gear grinding issue I was experiencing on my aging fishing boat. After replacing the gear oil and inspecting the drive, I suspected improper gear positioning was the culprit. The old shim had likely worn down over time, leading to the grinding sound and potentially damaging the gears.
Upon unboxing, or rather, unwrapping the Sierra International 1802067 Gear Position Shim 0.015in, my initial thought was, “It’s just a shim.” However, a closer inspection revealed a clean, precise stamping with no burrs or imperfections. The steel felt high quality, giving me confidence in its ability to withstand the harsh marine environment.
While other brands offer similar shims, I chose the Sierra International product due to their reputation for reliability and compatibility with OMC stern drives. Sierra International parts have consistently performed well for me in the past. My first impression was relief – a simple, affordable solution that could potentially save me a lot of headaches and money.
Real-World Testing: Putting Sierra International 1802067 Gear Position Shim 0.015in to the Test
First Use Experience
The Sierra International 1802067 Gear Position Shim 0.015in was installed in my boat’s OMC stern drive unit in my garage, during routine maintenance. With the lower unit removed, I carefully positioned the new shim according to the OMC service manual. Everything fit perfectly, suggesting accurate manufacturing.
After reassembling the drive, I ran the engine in a test barrel of water, shifting between forward, neutral, and reverse. The grinding noise that had plagued me was completely gone. The shifts were smooth and positive. It was much better than I expected.
Extended Use & Reliability
Now, after several fishing trips and numerous hours on the water, the Sierra International 1802067 Gear Position Shim 0.015in is still performing flawlessly. There are no signs of gear grinding or unusual wear. Everything has been solid.
The shim itself is, of course, hidden inside the stern drive, but given the smooth and reliable operation, I am confident in its durability. Marine environments are tough on equipment, so using quality parts is essential. This Sierra International shim inspires confidence.
Compared to my previous experience with the worn-out shim, this is a night-and-day difference. The boat shifts smoothly and quietly, allowing me to focus on fishing instead of worrying about mechanical issues. It definitely outperformed my expectations.
