I need to reface the cam followers on my H. The contact surfaces and the unfinished areas of the body seem to be the same hardness in a file test. Are they case hardened or is the same hardness all the way through? Has anyone here ever tried to cut one? MikeM, you have any experience with these?

FWIW, we "resurfaced" rocker arm tips using a large scotchbite disc on an angle grinder.

We'd clamp the grinder in a vise for stability and carefully roll the rocker arm tip, by hand, attempting to keep the arm as parallel as possible to the spinning disc.

Obviously not a precise grinding operation but with some finesse the finished product can turn out ok.
 
I don't recall ever doing the ones on an H ? I used to have lots of H parts so I'd of likely just switched out for a good cam and lifters. But I see no reason it couldn't be done. I doubt very much needs to come off ? I have an attachment for the valve grinder to do rocker arms. It just holds them in one position and you still manually have to follow the curve. Good chance they could fit in it ? How bad is the cam ?
 
The cams are worn, too. I was young and new to them then and didn't know much. I noticed the pulley would wobble up and down so I pulled it thinking it was the right side bearing. Turned out the left side bearing was shot. It caused the cam gear to work up and down which caused damage to the crank and governor gears and governor bearing and shaft. Fan gears were shot, too, but I put new ones in. Gonna take about .030 to clean them up. I can work out a way to grind them, just want to be sure I don't lose the hardness. Do you have any parts left?

I have a main case keep inside I think it has the cam in it. I'll have to see if it is any better than yours.
