Real-World Testing: Putting Sierra International 1802066 Gear Position Shim 0.012in to the Test
First Use Experience
The initial test took place in my shop, during the repair of an older OMC stern drive exhibiting noticeable gear grinding. Using the Sierra International 1802066 Gear Position Shim 0.012in, I carefully adjusted the gear positioning within the lower unit. The environment was controlled, clean, and allowed for precise measurement and placement.
Immediately, the difference was perceptible: shifting felt smoother and the grinding noise diminished significantly. While this wasn’t a high-stakes environment, the improved functionality was undeniable. No special tools were required, just standard mechanic’s tools for disassembly and reassembly.
Extended Use & Reliability
Over the past several months, I’ve used the Sierra International 1802066 Gear Position Shim 0.012in in multiple stern drive repairs. The shims have proven to be consistently accurate and durable, showing no signs of deformation or wear. Maintenance is virtually nonexistent; as long as the surrounding components are properly lubricated and maintained, the shims themselves require no specific care.
Compared to previous experiences using generic shims, the Sierra International shims offer superior consistency and reliability. Generic shims sometimes vary in thickness, compromising the precision of the adjustment. The Sierra International 1802066 Gear Position Shim 0.012in consistently outperforms, delivering noticeable improvements in gear operation and longevity.
