Well, I got an answer from the people over at  POR-15

Sorry we do not recommend any of our products inside a crankcase. Thanks, Mike

So does anybody have a recommendation other than the glyptol  (apparently only made in red?)
I need something brushable, I have no spray equipment.

Moving on  to other concerns... what is the best way to extract the main crank bearings?  Will I need a press to remove them safely?  I want to get the castings ready to paint.

Once the retainer bolts are pulled, the main bearings are usually only a slight interference fit in the castings. You might need a little bump from an appropriate driver or piece of hardwood to get them loose from the housings.

Check on electrical insulating spray "varnish", (this product is actually an epoxy resin). It comes in spray cans so no brushing needed.

@TX  Re main bearing removal (sleeve type bearings):
Mine did not come out so easily. new ones did not go in easily either. Checked for burrs, out-of-round, etc, none, just a very tight fit!
See this thread http://listerengine.com/smf/index.php?topic=7256.msg81907#msg81907

If we came up against a bearing/housing combination as problematic as yours Hugh, we would certainly go for the hydraulic press. It is my understanding that that situation is uncommon and might indicate parts that were not machined to normal specs.

Irregularities will sometimes crop up with just about anything that is dependent on the human touch and judgment, we appreciate your reports and feedback!

Thanks Gary, I think the "difficult to remove problem was related to those bearings being gooped in there for 60+ years.
I attribute the re-installation  reluctance to slightly oversized Indian replacements.
Just a guess on both counts, and in any event, they came out and went back in. Engine turns easily after setting up correct brg. housing spacing.
Now, to find some time to add a generator so I can give it a load for break-in.

Cheers,
Hugh

Will try to get the bearings out today, if the damn rain will stop. 
As to spray on types of varnish
Anybody ever use this:

Yes... that is a phenolic epoxy and will work great inside the crankcase.

Tried a couple of different pcs of hardwood to loosen up the mains...no joy..
Got one soaking now to loosen up the ancient goo...
Will a lye solution attack the bearings?
Other mandrels to try?

Is a hydraulic press available to you? That will certainly work. Otherwise, we sometimes use a socket with correct diameter and a hammer to knock them loose. Blocks of wood will work to cradle or support the housing.

Lye will eat the surface of your bearing and should not be used for cleaning same unless you are discarding the old bearings and don't care about their condition.

I will have to scrounge around to find someone with a press.  As to sockets that size, I am sure a diesel shop has tons of big sizes,
not me.  Just never have to work on stuff that large...(till now) ;D
I have all kinds of oddball shapes of steel laying around the blacksmith shop, but I haven't come up with anything
even close to correct diameter.  I am hoping to extract the bearings without damage to keep as spare parts.
Heck, I am still hunting an experienced welder to fix the bearing mount.
Its a good thing these are a labor of love....they can tun into money pits quickly!  :o

Yep, as a hobby these are captivating and fascinating machines. But as a business? - Difficult to justify in purely financial terms these days. The time invested can easily get out of hand even with very good parts resources. We do it because we enjoy it and derive considerable satisfaction from keeping some of the old iron productive.

We have frequently made our own tooling for specialized sizes or applications. Round aluminum stock is very useful for this purpose, but you could also do quite a bit with hardwood in a lathe. Wood can be less expensive and easier to work with than metal and for making one-time-use tools can be perfectly functional.

Hi TxB

I got mine main bearings out, and refitted them, by using a 12 tonne bottle jack on it's side between the - 12" x 6" door posts of my (200 year old, stone built with walls two feet thick) barn.

I first tried it vertically, as in the post (on here somewhere)  for straightening crankshafts but the lintol started to rise, there's only a a tonne or so of tin roof above it.

I found the cap of an old propane cylinder fitted as a 'dolly' and made support from timber offcuts.

Cheers
Stef

Re: the paint question, there's no reason to use anything other than a good quality oil based paint.  This isn't a gasoline engine.  Diesel won't attack paint.  In fact, the oil used in the vehicle that the paint pigment flakes are suspended in is very similar to diesel.  However, if you plan to use biodiesel, then residual alcohol could be a problem.  I have two engines that I painted the inside and outside of using Rustoleum paint in a quart can in 2005, and the paint is fine.  No reason to use expensive two-part epoxies unless you want to.

The cost on the spray epoxy enamel... negligible in the grand scheme of things. Easy and effective - about $8 to $10 a can. You can coat about 2 to 3 engines inside with 1 can.

+1 for the red electrical varnish (generic Glyptol).  Cheap and a very nice glossy finish inside.  Thanks to 38ac for the tip.
