We used an old single-eye electric hot plate for a lot of years to get balancers ready to install. A 1/2" thick piece of aluminum plate was placed over the heating coil, and the snout of the balancer was placed on it. After about 10 minutes of heating the balancer would slip onto the crank snout more than halfway and it could be driven home quickly with a BFH and a block of hardwood. When the balancer snout hits the timing gear it's at the right depth- - - -no need to measure.
