Balance flywheel/pressure plate yourself

[Eljaro]

Yea,.....you have to have everything that rotates including the washers and bolts and..and...and send it to the shop and watch them balance it with the crank and all the parts attached to the crank. Another broken crank would suck!!

Shortblock comes balanced from builder and it is not very practical to send flywheels and pressures plate from Spain to the US.
Of course all the bolts and washers were on it when I did the balance.I am not that stupid. The whole thing was set up again just to make the picture.

That's only good for static balance. It needs to be spun up and dynamically balanced. engine side and face side. Same as a tyre.

Of course this is a static balance.But with such a narrow piece there is no place to put weights all over. Either you weld a piece of steel to the pressure plate or you screw a bolt into en empty hole on flywheel.

The POINT IS that if you have to change the flywheel or the pressure plate or both or if you get a new rotating assembly and want to reuse the the old parts you CAN balance them this way without having to take them to a machine shop. If you happen to have one close to where you live who can do a dynamic balance.
In my case there is none.

I have used a tire balance machine to balance my setup. They have adapters that will allow you to balance anything if the center hole is clean without burrs. Static is a good place to start but spinning the assembly is better also if you have the clutch plate centered in the assembly. off centered off balance.
