I bought this old tractor a couple days ago, almost perfect sheet metal, fenders, everything but batt. box. Starter and generator are like new rebuilts. It's been in a shed for the last six years and has'nt run.
When I looked at it the manifold was busted bad and tappets sounded loud even over the exhaust roar. So tonight I pulled the valve cover and there's no sign of oil in there from recent years. The rockers and valve tips, along with the guides are junk. It's got good oil pressure on the gauge. Is the oil passage possibly plugged or a cam bearing spun and what lubes the cam lobes if there's no oil to the top?
This is just a nice straight old tractor, still six volt, gas tank even looks new inside and out. The good news is I don't need it, I was just trying to find a big brother for my Super C.
 
I assume the oiling system is like my CASE tractors. Are the oil journals in the common rocker pipe/shaft lined up properly? You have to push the rockers aside to notice,

The center cam bearing provides lube for the rockers. One way to check is to drop a small rod, preferably unfluxed brazing rod, down the oil supply hole in the head. Turn the engine over 2 revolutions and if the rod doesn't drop when the cam slot rolls by - the opening in the bearing hole is blocked or the bearing has spun. It is also possible that it never was installed correctly.

Oil from the rocker assembly runs down the push rods to lube the cam followers. Cam lobes also are lubed by oil slung off of the rod journals of the crankshaft. If the oil pressure is good as you say, the cam is probably fine.
 
Thanks for that brazing rod tip, that gives me someting to go on and I sure hope your right about that cam being ok. Jim
 
Theman's idea of the rod is a perfect test.
Do it with a hand crank, or other non starter means with the plugs out slowly. If done rapidly, a piece of brass rod can be cut off in the passage!
Be sure the center passage for the oil is clear. Checking all the stands to be sure the correct one is in the center is also a good idea. JimN
