This tool is a time saver, I wish I had found it yesrs ago. Prior to installing the harmonic balancer I needed to install the new front seal, so I thought I would find a way to use this tool, I placed a socket of the correct diameter of the seal, installed the tool and the deal pressed in perfectly the first time. Then I installed the harmonic balancer, the entire process took 19 minutes. Amazing.

Tool worked flawlessly. I used for the entire build of my BBC 427. Threads, washer and bearing were all of excellent quality. Even though I was installing the balancer on a old crankshaft the tool did have any problems.

This is wonderful and works great but it doesn’t come with a case to keep everything together.

Good quality. Surprised.I had my doubts so I greased the daylights out of it and the crankshaft before use…my 8” harmonic balancer eased right on.
