Harmonic Balancer Installation Tool

I ended up tossing my damper in the oven at 200 (I think) for maybe 20 minutes or so. I used an infrared temp gun to make sure it didn't get too hot to screw up the rubber. Then I got some oven gloves, a hammer, and a block of wood. I quickly took it out of the oven, seated it on the crank, and gave it a good whack or two with the hammer on the wood to get it started. Then I just used the crank bolt to pull it down. It was warm enough that it drew down pretty easy with an impact gun and didn't seem to fight too much. Not sure how much difference the heat made in the long run, but it seemed to go on easy enough.
