Review on Shankly Harmonic Bearing and Gear Pulley Puller with Dual Jaws for Maximum Efficiency by Daniel Jackson

The design is simple. I needed this for the narrow jaws on the end that did a good job of pulling my gear out of the recessed case it was in. However, after exiting the case, the puller was unable to complete the removal. The hands have no way of keeping tension on them to prevent them from spreading. First, the body interfered. After cleaning the hull I had to get creative and use other tools to push the levers down to keep them from falling apart. Ultimately, it did the job, but with a lot of help.
