1. Just warm up the crank gear in the oven (about 300 degrees for about 20 minutes).
2. Grab it with your gloved hand, line it up with the keyway and slide the gear, chamfered side first, onto the pre-oiled crankshaft nose.
3. Place the pipe between the thrust washer of the balancer tool and the gear, quickly thread the balancer tool into the crank nose, and turn the nut against the thrust washer, which pushes on the pipe and in turn pushes the pipe against the crank gear.
I hope this helps,
This is almost exactly the method I use except I don't heat anything. What I use is a piece of square tubing that has an inside dimension just larger than the snout diameter (1.25) and long enough to ensure the gear is seated. The ends of the tubing are milled square. I then press it on with my balancer installer. By using square tubing I find that there's clearance for the key and it still contacts the gear and my installation tool.
