I installed my harmonic balancer I got from Summit and am having a few problems. First, I thought I had it installed properly so I put on the crank pulley. When I went to install the water pump pulley today it wasn't even close to lining up with the crank pulley. So now I'm thinking maybe the balancer isn't on far enough. To install it, I heated it up per the instructions, slid it on as far as it would go and drove it the rest of the way (or at least what I thought was the rest of the way) with a 4x4 and hammer until it didn't go on any further. I then tightened the bolt with my torque wrench to 90 psi per the specs and thought all was good. However, it is not. Secondly, the timing marks on the balancer read the opposite direction from the marks on the timing tab on the motor as shown in the pictures. Why would this be? The motor is a 72 400 with the stock timing cover/timing tab.
