Why Balance?

All automotive engines can benefit by being balanced when they are rebuilt. If you have performed any of the following:

Replaced the Pistons
Ground the Crankshaft
Replaced the Crankshaft
Resized the Connecting Rods
Replaced the Connecting Rods
Replaced the Flywheel
Replaced the Damper
Replaced the Flexplate

your engine will need to be balanced to attain the longest life and performance of your rebuilt engine.

It's a Fact! 28 grams of unbalance 4" from the center of a rotating part at 4,000 r.p.m. causes a force of 112 lbs!
At 4" 7 grams 14 grams 28 grams	2,000 r.p.m. 7 lbs. 14 lbs. 28 lbs.	4,000 r.p.m. 28lbs. 56lbs. 112 lbs.	6,000 r.p.m. 63 lbs. 126lbs. 252 lbs.	8,000 r.p.m. 112 lbs. 224 lbs. 448 lbs.

Most factory Engines are produced on an assembly line where the parts are not balanced as a matched assembly.

Each individual part has a tolerance as much as +/- 14.0 grams for production purposes on the Harmonic Damper, Flywheel, or Flexplate and each end of the Crankshaft. If the imbalance on these parts should line up with each other, an unbalanced condition would be the result - causing vibration and a shoftened Engine life. The factory plans for this situation by predrilling the Harmonic Damper and Flywheel so they can add weights to counter the imbalance after the Engine has been assembled.

Balancing the Harmonic Damper, Crankshaft, and Flywheel as an assembly is the method required to achieve the most accurate results possible!
