I share this because It keeps coming up as a topic of discussion in my garage all the time. I have a couple of younger friends that like to come over and talk about the "great" cars there going to build. 900 hp small blocks. One thing that always seems to baffle them is the installation of the harmonic balancer. I am getting to the point where I get pissed when one says" I'll just hammer it on" AARRGGGGGHHHHHHHHH!!. here is my explanation. On the crankshaft, there is a flange called the "thrust flange" in the bearings there is a "thrust surface". When you hammer on the end of the crankshaft, you also hammer on the trust surface. bearings are soft. you can distort the surface and I have even seen people crack the crank bashing on that new balancer. Many company's make balancer installers. I have one from snap-on. Cost me 60.00 but comes with thread adapters to do all american threaded engines and several metric engines. If you don't want to buy the tool, Just use a longer bolt and "gently" pull the balacer on. This is one of my pet peeves when building engines. Next class- excessive silicone!! your right. I don't understand the jeep thing!
