Flywheel Clutch Install Torque and Balance

[BYprodriver]

All good questions pjq, you are thinking, not overthinking.
As Spendy said 1/2" breaker bar with a angle gauge is best. 1/2" torque wrench will work just set it on the highest value, & try for smoothest, continuous,pull.

In order to dynamically balance the flywheel & pressure plate they must be mounted & spun at simulated engine speeds using actual bolts. Easiest way to do this is with the pre balanced crankshaft. Dual mass flywheel is difficult to balance perfectly, but I believe it is the greatest source of imbalance, pressure plates can contribute also but you can't remove much material, so often weight must be added to the light side. Don't forget the front pulley, bolt & washer too. I always shoot for a 1/2oz tolerance or less. After balancing my engine I was amazed at how much smoother it is. With stock exhaust it's boringly smooth & quiet!
