Title: 0.010" undersize camshaft? Post by: ardiesse on October 26, 2019, 07:54:38 PM Does anybody have a camshaft with 0.010" undersize journals?
Tried fitting a replacement camshaft to a motor which came minus camshaft, without success. The alternative is to replace the cam bearings with a standard-size set. But I don't want to do that (yet).

I'm beginning to lean that way. I have a contact in Echuca who has machined up some cam-bearing-removing-and-installing drifts. But otherwise it wouldn't cost that much to have an engine shop remove and replace the cam bearings. Rob Title: Re: 0.010" undersize camshaft?
