I turned over this little piggy to the shipper on September 2, in Newcastle, WA. She got here yesterday. They wanted a commercial address on this end so I gave them Ocean State Harley-Davidson’s in the next town over, Warwick, RI. Amy Bishop and other friends there kindly helped me load the bike into the back of the old Ford for the final 3 miles of the journey.
After 20 days on trucks and sitting around in warehouses in Washington, Illinois and Massachusetts, all my stuff was still aboard. No pilfering. It would have been a pain having to replace a few hundred tools, parts, camping gizmos…
First thing I did was dump engine parts on the porch table and have a closer look. Consider it a coincidence that I happened to sort through them on the obituary page. The iron piggy has miles to go yet, continents to cross. Up and over craggy mountain ranges and down across blistering deserts. But maybe with an oil cooler next time.
You can see where the inner cam bearing failed, chewed on the top of the camshaft on the left. Stock INA bearing, not the full-rollered Torrington. Maybe the heat would have killed a Torrington, who knows? That damaged shaft operated the valves on the forward jug, where I heard the ominous tink tink tink…
Bearing bits went through the oil pump. That’s the pressure gerotor on the left, scavenge on the right.
The pump housing is scored as well, no surprise. I wonder what I had for oil pressure in the high desert of eastern Washington when the engine let me know a major failure was imminent? Will be equipped with an oil pressure gauge next time.
I put a dial indicator on the pinion shaft yesterday, where it passes through the cam support plate. I was expecting to measure runout at .030+, found .002 instead. That tells me two things: The MoCo did a nice job press-fitting this crank at the factory and my bottom-end bearings are still sound. That’s fairly remarkable, I think, after 70,000 punishing miles and a cam bearing failure. Trouble is, I’m sure some stray metal got down into the cases, so when I say the bearings are sound I mean sound for now. The magnetic drain plug looked pretty hairy when I drained the oil.
I’m tempted to put the cam chest back together with new parts and just run it, but the unaccounted-for bits make an argument for tearing it all down for a major overhaul over the winter. So does the look of my lifter bores. I’d have to split the cases to get the bores honed to a standard oversize. Haven’t measured there yet but just by feel I believe I’m missing metal.
Finally, here’s one last pic requested by a friend and fellow biker, Bill Stenger, in Pennsylvania, who wanted to see the trusty old Ford from the front.
