  1. Great Product 5 Star Review

    Great product, no issues with installation. Purchased several sets both for an Align and OS 91HZ engines.

  2. Didn't last one half of a tank 1 Star Review

    Posted by on 11th Apr 2014

    I purchased and installed these bearing in my OS91 speed. I hold an A&P certificate and have access to the proper tools to install correctly. Upon finishing my install and the subsequent test flight resulted in the rear bearing coming apart and FOD damaging the engine. I now need to replace the connecting rod, piston, wrist pin, sleeve, crankshaft and bearings. Previosly I used Boca Ceramic bearing which lasted 35 gallons.

    Since no tools are needed to install these bearings, I am curious as to what tools you used to install them. Improper installation can lead to premature failure.
