yeppa, sort of figgerd any one called zippo would understand

Harmonic balancer for the diff. Don't ask me exactly what it does or how it works. When I asked the question last, all I got was smart alec responses from enlightened ones whom did not have an answer. Ha ha, mock you muthers, but there was no reasonable answer as to how a harmonic balancer actually works.
Is there anyone that can actually give an educated response??

Cheers,

Jason

DUH as i said. "Harmonic" = vibrations. "balancer" well high frequency vibrations you don't balance you just add mass to dampen or absorb, IE suck them up.

in simple terms is a hunk old cheep metal that's attached in such a way as to make vibrations not noticeable to the diver and occupants.
the same arrangement is found all over the place, motorbike handle bars for example.

ops sorry i forgot the educated response bit



Structural Vibration - Analysis and Damping

its a vibration dampener it works by suspending a mass thats free to move (within limits) against something that can vibrate in ways that you dont want.

when the primary item starts to vibrate the mounting system for the weight (in this case a gearbox mount and a lump of steel) the inertia of the weight and the flexability of the mount absorb and remove some of the motion of the primary item.

Cheers to all the educated. Thankyou
