I am finally getting around to tearing this engine down from a donor 52 3600 that was left without a a head out in the weather for heaven knows how long. The cam is broken in place. Pistons are glued to cylinder walls, one rod is broken. I am down to clutch, crank, cam and block. Can’t turn the crank to get to the clutch housing bolts. Can’t turn the cam to get to the cam retainer. I’ve taken all main and rod bearings off crank. I have no aspirations of saving any of this for use as an engine. Maybe some cam door handles or a crank coffee table. You’ve seen those glass topped ones around. I’m stuck and about to
Get the torch out. Before I do that any ideas on how to get the crank freed up. I do not want to waste time on freeing the pistons if possible.

Cut the crank into behind the rear main brg'

Drill and tap the cam gear for a crowfoot puller like the one used for a harmonic balancer. If the cam gear is the fiber type, just break it off with a pry bar. Once the cam gear is off getting to the thrust plate bolts isn't a problem. PB Blaster or Kroil in the cylinders, followed by heating the piston crowns with a torch will usually free them up enough to turn the crank. I like to use the chisel end of a shepherd's crook wrecking bar between the flywheel teeth and the bellhousing to help turn the crankshaft. Once the pistons free up a little, things usually move along pretty quickly.

The flywheel and then the bellhousing can be removed if won't rotate. Get out your 1/2" drive U-joint and 6" extension, I have done it.

This one sounds like a better candidate for a boat anchor than cool decor. Removing any more parts will shrink your potential market since a lighter anchor will not be suitable/desirable for the bigger boats.

I don't disagree. Another hour or so and it's off to the scrap pile.

Maybe it isn't just me. There are many parts of these old engines which stand out as pieces of art in my eyes. My favorite is the original brass accordion bellows t-stats.

Certainly a beauty to behold!

Nice to look at- - - - -utterly worthless in a pressurized cooling system! Those things were designed for maybe 4 PSI, maximum!

Thanks Fellas for the ideas. In the end Jerry’s point about the fiber cam gear was key. I beat it off got to timing plate screws then everything came apart fairly easy with a little help from the torch. All the bolts and screws are bagged up. Just never know when they might come
In handy. It turned out the cam was broken in two places...must have been a rough ending.

So now you got me thinking about taking all of the moving parts of my old unusable 216 and put them all together as they are supposed to go except there will not be a block or head in the way of viewing the assembly of parts. Kind of like a T-rex skeleton at the museum.
I have a welder and a dream...

I like it. Great tool for showing young'uns how an engine works. For display purposes, once assembled steam clean. Wipe down with cleaner then cold blue it. Build a nice oak or walnut display table and set it in a prominent place in the living room. I LIKE IT!

I was thinking about hanging it from the ceiling in the garage like its floating in mid air.
It will be heavy, but I have some sturdy aircraft cable t hang it with.

Now your being creative. Sounds pretty cool.

It would make a great Christmas or birthday gift for the wife. I'm sure she would appreciate is, mine always has kind comments when I suggest similar ideas.
