| + | VERIFYING TOP DEAD CENTER AT THE DAMPER/POINTER WITH THE MOTOR ASSEMBLED. | ||
| − | , | + | First off, the large round hub on the front of the crankshaft is called a harmonic damper by some and a harmonic balancer by others. If it is bolted to the crank of a 350 Chevy that is internally balanced, then it serves only the function of being a harmonic damper, dampening vibrations (harmonics) that are created in the crankshaft. If it is bolted to the crank of a 400 Chevy, then it is both a balancer and a damper because the 400 is externally balanced by using eccentric weights on the balancer/damper and also on the flexplate. |

| + | In this exercise, I am suggesting that you install the piston stop tool with the Factory TDC notch on the damper ring to the right of, or past the timing pointer so that you can turn the crank clockwise through the whole operation. If you install the stop before you are to TDC and then turn the crank backwards until the piston comes up against the stop again (counterclockwise), you may loosen the bolt in the crank that retains the harmonic damper. Then you have to get your buddy to crawl under and hold a large flat-blade screwdriver into the ring gear teeth to keep the motor from turning while you tighten the bolt back. Far better to just turn the crank clockwise only (keeping the bolt tight) and sidestep a problem before it occurs. Been there, done that. | ||

| + | You'll need to get everything out of the way so you can work on the damper ring (the damper is made up of two metal parts that are joined together with an elastomeric material) is the outside ring which has a notch indicating top dead center when aligned with the pointer on the front cover of the motor.
