Tin Man


I worked at it for weeks, but I wasn't able to get the engine free before removing it from the frame. I'll have to get the head off once it's in the vice. Although, I do think that it's frozen in the right cylinder. I could hear the left move as I rocked the crank.
 
For one piston to move with the other one frozen in the bore would mean SERIOUS issues in the rods, crank, or at least one piston pin bore!

Could be. I'll have to get the head off to get a peek inside. Do I need Whitworth's for this?

Yes. The most problematic is the nut on the underside of the head, between the barrels at the rear. This is 1/4 Whitworth or 5/16 BSF (0.525", 13.34mm) and you will need to thin down the outside of a box end wrench on a grinder to get it in there.

I've ordered a set of Whitworth sockets and wrenches. I should have them by the New Year. How, pray tell, do I get the proper torque on it when reinstalling the head?
 
Good man. I have had mine since the 80s.

Then about 5-6 years ago, I inherited a whole whack of WW/BSF tools from my father in law, who used to be a machine operator for a hosiery company in the 50s-70s. A load of wrenches and 1/2" sockets up to 1 1/8". Happy!

That would be helpful.
 
I purchased the bike from an old vet biker by the name of Bird. He gave me a title and a lien release with the bike. I thought that I could register it but failed to notice that the lien release was not notarized. The title was last transferred in 1983 by the original owner, Mr. Greene. The second only put 2300 miles on the bike before he parked it. From the looks of the valves, I suspect it was burning oil and fouling plugs on the right side. I don't know if the 2nd owner ever paid Mr. Greene for the bike.

Through the marvel of the internet, I learned that Mr. Greene had made his transition to the Great Beyond about 8 years ago. I thought that I would never get the title. But as luck would have it, I found his widow on Facebook and she was kind enough to notarize the form for me. Her comment about the bike was that she loved it because it "roared like a man"! I've promised to stay in touch with her throughout the build. Thank you Shelia! You're the best.

Maybe someone knows the history of this bike.

I'm now the 3rd owner.

The right exhaust port is fine:

The bottom is debride in preparation for splitting the cases:

All cleaned up:

The lump is frozen because there was an inch and a half of water in the right cylinder. I hope that the bores can be saved:

I love the disassembly stage, lots to explore.

You were the one that said it was bad news to have one bore frozen.

Everything was tight and intact. I wonder how the water got into the engine. It may have been the hurricane it sat out in, the weekend before I could pick it up, but it looks like it has had water in it for a long time.

He also said he liked it when everrything was cleaned up. The guy's just hopelessly in love with these old crocks! :lol:
 
It's bad news because it's going to be either A) hard work, B) a long process, or worst of all, C) BOTH!

You are right again. I think both.
 
Thanks Tin Man for lessening my angst over my own build. Sometimes it helps to see one that is more challenging. Best of luck.
 
I am sure you will enjoy every minute of it - I did and still not quite there, looks a great project - enjoy!
 
Crank shaft end play is in specs on tear down.

Camshaft has too much end play:

Pistons ar STD, so it looks like the barrel can be saved.

Timing gears and chain appear to be in great shape.

I've really been slowed down on this project. First with the titling issue, which is now solved, and now my sailboat still needs to be repowered. The 40 year old 12hp diesel locked up over the winter (the salt water has not been kind to it), and now my father is in intensive care. Time and money are at a premium, as always. My apologies to Leo and Don for slowing down my purchases.
