Bryan Posted June 16, 2022 Report Share Posted June 16, 2022 Was checking out my camshaft (again) against the new bearings I have. Measuring all with .003 clearance, which is the max limit in the service manual. The 53 Dodge camshaft measures exactly the same as the 48 Dodge engine camshaft measured. 1st - 1.9980", 2nd - 1.9660, 3rd - 1.9350 Rear - 1.248" I would think if these camshafts were worn I'd be seeing different numbers between the two. I oiled the first new bearing with gun oil, rubbed it thin with my finger and tried it on the first journal. Can't feel any play. Anybody know if .003 in the book is like the ring gap clearances? Book says one thing but in practice might be more? Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted June 16, 2022 Report Share Posted June 16, 2022 How did you measure the clearance? If you measured the journals with a mic, and the same with the insides if the bearings, keep in mind that the bearings will compress slightly once installed. It would be more accurate to mic the bearings after installation, then calculate your clearance. 1 Quote Link to comment Share on other sites More sharing options...

Didn't know they compress. Any kind of data on how much they change, installed vs uninstalled? Thanks. Quote Link to comment Share on other sites More sharing options...
