Never...NEVER....hammer a cold harmonic balancer onto a crank. The way most of us old timers do it is to place the balancer in a pan of boiling water for 5-10 minutes. Quickly grab the hot balancer with your wife's best towel, duck her blows, and run out to the garage. Place it on the crank, place a 2X6 on the front pf the balancer and then hammer it on. Metal swells when hot and shrinks when it cools off. Trying to hammer on a cold balancer runs the risk of getting it 1/2 the way on and then not being able to


i havent been in a good argument(i mean discussion) in a long time and as useual i dont know what im talking about, but anybody believe you can put a HB in a pan of boiling water, take it out, run to the garage get it lined up and knock it on and believe that, that hot water made a dif. then i dont know what to say. it would have gone on as easy if it hadnt never seen any water. i dont believe 230 degrees for 5-10 min. would expand a HB hub enough anyway, but 5 min. later i know it wouldn't. there was thousands of them knocked on without any hot water.
we have 2 opinions now one say it will ,one say it want, now we need some facts.
im not trying to make nobody mad, but i would like to see some more opinions on this.
