Default Re: Noisy metal timing gear cured by torsional damper

Hi SAJ
As a result of PMing you and learning the source of your New Zealand made torsional damper I was able to purchase one from Errol McAlpine.
Fortunately the motor in my speedster is set back 4" in the chassis which simplifies replacing the pulley, although I did have to lift the motor to clear the front cross member.
My motor had similar characteristics to yours, quiet at idle but with a very loud clatter from the timing gears under load and vibration periods through the rev range.
The torsional damper was a revelation and the car is now a pleasure to drive.
We have just completed a 300 mile trip cruising around the 60mph range and thundering up the steeper hills (Kaimais and Bombays) in either the 41% overdrive or occasionally having to drop down into top gear for tight bends or steeper inclines.
The change is a simply fantastic!
