Slant Six harmonic balancer install tools
I have three of these to give away, just pay the shipping. They will fit in a small USPS box, so $10 will do the trick.
When I assembled my first slant, I didn't want to use a bolt in the crank nose to pull the balancer on - I was concerned about stripping out threads if the balancer was super tight. So I made these things from a chunk of all-thread. I've used mine several times, it works great. Thread it into the crank, use the double nuts to hold it still, and tighten down the balancer with the third nut and the washer. These have had the threads chased on both ends and the sharp edges were smoothed out. I'm giving away just the all-thread, you will need three nuts and a big washer to make your own tool. Shoot me a PM if interested.
