Which site is that? Any link to an interesting (and perhaps thread-related) topic there?
Dana, Here is one of the welding sites KoO posts on , (I'm sure there is others ) http://weldingweb.com/forum.php
I have read some fascinating and quite technical threads on freeing stuck engines over on smokstak ,
Have you ever looked at This Thread at the first site? It was supposed to start where Post 11 is (when two threads were combined), but the moderator got things reversed. It used to be the third-most viewed thread on site, may still be.
I have some old copies from Smokestack, back when it was just a hardcopy magazine.
Biggest engine I own and freed was a one-lunger with 6.5" piston and 32" flywheels, but it had no rust or corrosion so was fairly easy.
Never knew that about the Stak, will have to be on the lookout for some original issues
Have a 1930'ish T20 IH crawler with a 4 cylinder gas engine ( ballbearing crankshaft mains) ,When first acquired it was stuck pretty tight
with water down the exhaust etc, after popping the head off I decided it needed to come completely apart , Then I found this
View attachment 149147
My best guess is at some time in its life it was stuck (but good) . Then someone decided they would pull it with a much bigger machine and try
to break it loose , Well there is what happened
Is that looking at a bent rod, with the bottom of the piston showing on the top right? A bit less magnification might help.
Did you check out the thread I linked to in my post above? Saturday night should allow enough time to do it justice.
I downsized the pic above and added a couple more , This may help orient the view
I made it about halfway through your linked thread so far Dana, very entertaining
In the first picture, what had first looked like a lifter (without close inspection though) is now clearly a cam lobe. Is there enough good material in the cylinders to just rebore them?
I was rather pleased at the interest in and additions to that W.W thread; my contribution started at Post 11. I really need to go back and add a few new pictures of older machines I 'recently' acquired; even if they aren't super great models, one is an old Lincoln classic and the other was used building some great equipment.
BTW, you might consider cleaning that piston 'assembly' in oxalic or phosphoric acid and put it on display...
The cylinders ( wet sleeves) have been replaced with better used ones ( cleaned ridge reamed,and honed, resealed ) , The engine has been
mostly renewed and refreshed , The lower end is going back together , However my Travelall kinda took center stage for the past few years
I have been using my electrolysis tank to clean up a few pieces and parts lately though,
few pics ( after cleaning ) of main clutch pressure plate
and a few of a genuwine IH early 30's thermostat and housing
Had to pull the head off an old international in a 1950 Cleveland ditching machine a year or two ago. It was stuck so bad it took two of us to get it unstuck- one with a ten on sledge and the other with a four foot cheater. I told thing those pistols are extra thick! A little honework,new head gasket and a couple of valves and she s still chugging along. Does anybody remember what model the engines are that start on gas then switch to diesel?
And does anybody know how to turn auto correct off on a tablet?
I would love to learn that for all my devices!
THIS is exactly why much earlier in this thread I said to not monkey with it overmuch and pull the head!
I agree - if I can't soak it for a week and get it free then I just pull the head,mainly cause of its that bad it's probably going to need a hone, but op was asking ways to to free it without pulling the head. I do think that the next one I get that's locked up i am going to try some of that evap o rust in the cylinders though. I never used it for that,but it's worked well for other things, so who knows? Has any body else tried it?
Saw a video from the Wheels Through Time museum and they put a hot plate under seized motorcycle motors and once the engine warmed up they got them freed...
Found 3 bent pushrods as I was removing the cylinder head. 3 of the 6 pistons were seized. One of them freed up with a 2x3 and a hammer the others I had no luck with YET but will try again tomorrow. The cylinders really dont look all that bad.
You 'll get em. Any luck finding gaskets? I am guessing you pulled the crank as well??
The gaskets are hard to find as a complete set I have looked everywhere but ended up finding some through ebay one at a time. Yea no the crank isnt coming out on this one. Get it all freed up clean the cylinder bores and run it.
Glad you found them. There is a place out here in Odessa that makes just about any gasket you need. Found some for the gas/diesel I did up in Oregon or wasington. Maybe you can teach me something new. Unless you are driving them from the bottom past the rust ring,and haven't pulled the crank then how are you freeing them one at a time?
I'm in a similar sort of boat (thread over on triple-diamond forum) with my SD240--I'm more or less where you're at now. Are you driving the pistons out through the top with the rods disconnected from the crank?
I haven't been on here in a while because of other projects but I will try and keep up on the IH build. Yes I had to disconnect the rods and drive them up down and just about sideways with lots of penetrating oil. There was a bunch of junk in where the rings are and they were stuck right in so I had to work them carefully to get them to come out from the crank side. The engine I am working on is still in the truck so the crank is still in the engine. The problem I was having is two pistons were stuck and one was at the top of the cylinder and the other was at the bottom of the cylinder which didn't help because the crank wasn't putting all of the pressure straight on the piston like if it were half way in the cylinder.
