My 1956 Ford 850 (not 350, as I posted a minute ago) has suddenly developed an engine vibration at around 1200 rpm. I've got it apart now, so I can't do other tests, but it vibrated at that speed even in neutral. An oil leak that developed at about the same time might be related or it might just be that I inadvertently overfilled it, because it stopped once the dipstick stopped showing a little bit overfull. A tractor mechanic doubts my theory, that it's a main bearing going, and my tests for play on the crankshaft pulley tend to agree -- they show hardly any play at all. He thinks it might be a clutch problem. Any ideas?
