Just posting a general question here. I have been working on autos and tractors for 50 years. I replaced many a failed camshaft in cars
years back. Mostly just Chevys back in the 60s and 70s. They were known for poor quality cams and lifters.
When it comes to farm tractors? I think I have only ever seen one worn-down camshaft in my life. That was on a Minne-Moline.
Up to this point, I have assumed that tractor/industrial camshafts were made of more hardened steel instead of the way Chevy cams were with
soft castings and a thin surface hardening.
I am asking this because of a Ford Jubilee I just picked up. Engine sounded fine after I got the fuel system cleaned up after many years
of sitting. To my surprise though. I pulled the valve cover off to adjust the valve-lash. I found one rocker with over 1/4" clearance.
It is not from a loose adjuster. Something is obviously wrong inside the engine. I suspect a worn cam lobe. I am going to pull the oil-pan
off today and peek inside. I never messed with Ford tractors much but also never heard any bad cam stories about them.
