..... Some engines are noisy and some are quiet...it has to do with the centers of the cam bush holes, idler shaft, and crankshaft main bearing. Ones which are slightly farther apart, are noisy, closer together are quiet.
sorry to drag this old post up the line again however there`s something I need to know:
Aren`t there any bigger (or smaller) gears (camshaft, crank, intermediate) available ?
See, at my ole Shovelhead I once needed to exchange the wheel of the camshaft.
But there are 5 different sized gears available. The diameter differs by 0.01"
With some hardenend steel-pins I borrowed from my local Indie-Shop I was able to find out the correct sized gear (which are color-coded).
Is there something similar available for our ole engish girls ?
Either the tappets or the gears is it intermediate, cams, crank are giving me headache....
btw: Is there a way to get the camshaft out without taking the tappet-block off (and therefoe the cyl.-head) ??
