You could use a high point balancer. I think theres a bit of debate about this, I've heard that the engines vibrations from spining at high RPM's defeats the purpose of balancing the fan. Then again, I've also heard people say that you should balance it. -- Gentlemen, we can rebuild it... We have the technology....Better…stronger…faster...--

I BELIEVE THAT THE VIBRATIONS VHF MUST DISAPPEAR, AND THEREFORE THE FOAM IN THE TANKS!

The vibration from the engine is not the same type of vibration as a out of balance fan.

If the fan was severely out of balance generates damaging vibrations, that can actually damage the engine bearings.

A static balancer can only check the balance of the fan sitting still. The proper way is a dynamic balancer which many of us do not have access to.

If the fan is already balanced install the fan so the magnet is opposite the piston when its at TDC and don't worry about it.

I have two metal fans, one is perfectly balanced with a counter weight and the other one has a magnet and the other hole topped off with jbweld or epoxy, they both run smooth as glass.

Runout will cause more vibration than a governor magnet.
