Quick question here, while assesing my parts supply to build the new motor for the '78 I find myself really short of nice rocker assemblies, shafts and arms. Problem is all 3 of my cores a '77, '78, '79 have had less than ideal care as oil changes etc have gone in their lives. The '77 and '78 have about 150k on them the '79 is unknown. Now the thing is this, out of all of them, 12 rocker assemblies I might have a mere 2 arms with their related half of a shaft that show only "polish" and no ugly wear. The rest all have some varying evidence of galling, with some having at least one nasty scrape that will EASILY catch your fingernail, some with a couple of scrapes per rocker, some with nasty pitted galled patches of metal. Sometimes the arm is better than the shaft, usually both are about even. I am in a quandary as unlike bug parts, you just don't go out and buy sets of T4 rocker assemblies for $100 or so. If I stick to the best set out of what I got, how should I clean em up? A bit of hand honing with emery cloth I figure? The other thing of course is only the loaded side of the shaft toward the head has wear. I could I imagine flip over the shafts to wear the previoulsy unloaded side. The only difference I see is that the mounting holes are chamfered on the side toward the head but I don't see that chamfering the other side would hurt. Anyway anybody with advice, please do tell. I also seek wear specs on the shafts and bore in the arms, mine all feel a tad loosish, the Haynes manual (the only one I got at the moment) only gives a spec for the shaft so far as I can tell. Oh I note that the '78 still runs fine with it's shafts being some of the worst of the lot so maybe this isn't such a big deal, sure looks bad though. John
