Got this stuck 50 Olds 303 motor & Hydramatic + other goodies from a guy, it looked better in the truck then i opened it up with 30 bolts to remove from the torque converter/ flywheel, my plan is to lift the trans & crankshaft as one then remove the bolts and get at the crank bolts remove the hydro Ever thought about starting a motor that's been sitting open it's hard to know whats inside, well a picture is worth a 1000 words Took the oil pan what you see is cotton, jute carpet mat the mice stored & a mouse lots grease & oil - none of it is dirt Rob said it was a Rat motor
Was told you can't get the Hydramatic off a a motor that's stuck had a few ideas that worked Had trouble with 2 rod nuts near the cylinders took a long time to get them out next knocked the 2 dowel pins into the block to separate the block and trans rotated the flywheel & crank to remove the 30 converter bolts the 30 bolts were removed It's apart - block with the stuck pistons - flywheel - Hydramatic & crankshaft might try to knock the pistons out of the block later
Damn, that's even uglier than the Canadian alum. flathead I had until a few years ago. Neglect and weather sure take their toll........
Don't worry, it will all be worth it! Get some hardwood blocks, a big ass hammer and get to work knocking out the pistons!
Don't knock out the pistons. If you cylinder walls are not busted now, they will be when you are done. Either melt the pistons out with a torch, or take a drill and drill holes in them until you can knock the centers out, then a hacksaw blade until you hit the rings, and a cape chisel to collapse the piston onto itself. Those early olds can be bored a long way and that block is more than likely savable if you don't wreck it taking the pistons out.
A few years ago I field-pulled a hydro off a '56 Pontiac motor that was set up, same deal, pop the pan, pull the crank with the trans. I have to think once in a while you'll get one that's stuck in a position you can't get on some rod bolts, but for the most part you can get enough room that if you have to you can spin the trans case (or the bellhousing some cars use with the Hydro) around to get to the converter bolts. Easier than moving the rest of the car's going to be, that's for sure.
For that block. I've got a little outboard boat engine which had been dipped in the sea water quite a few times and was left sitting for quite while. Crankshaft and all was seized. Left it soaking in Diesel for one night and did the jub. Maybe sticking the block in Desel for up to a month might do the trick???? Just my 2 cents.... HC.
We tried to knock out some real bad stuck pietons and the block cracked in the process. So we did another one by drilling out the center of the pistons then take out the rest with a hammer and a drift. That worked and we saved the block. It was a 409.
had two rod nuts in a no access position i thought till Chuck came over, we used a 9/16 universal socket barely got it on, then the breaker bar and a pipe did the trick next step was to chisel the nuts, glad the breaker came through
