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.

I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
