Crankshaft Pulley/Pulley Engine Tin Question

[isomeades]

Hey There,

Working on getting the new (to me) engine in my bus set up as close to properly as I can manage, fixing all the jerry rig shenanigans we had from my "side of the road" install. I knew I was going to have to face this at some point, and that time has come.

Here's the issue today - The crankshaft pulley is seized, and I mean seized, in place on the crankshaft. I've tried removing it with the classic 2 large screwdrivers, applied heat, applied ice, anything I could think of, it didn't budge. So, following the advice I saw here on the forum, I went and got a set of 2 jaw pullers, and used those on it (after heating the pulley wheel with a torch to increase my chances. No Dice. In fact, it actually started to bend the pulley around the stamped puller holes. See the photo below...

Now my dilemma is this. I don't currently have the pulley engine tin mounted on the engine. I have the piece off my old engine, which does mate up properly with the '72 type 1 conversion tin I have (it seemed to match up fine when the previous engine was installed). How am I going to install it?

My Dilemma

As I see it, the options are

A) Figure out how to get the pulley wheel off (suggestions, anyone?)

B) fins some way to install the tin without removing the pulley wheel. I can see this would almost certainly involve splitting my engine tin in two so I can even get it in place, and I can't see any way of accessing the bolt holes for it behind the pulley wheel short of cutting new holes in the pulley wheel. Has anyone ever been in this situation before? And if so, any suggestions?

Thanks, and any help or ideas are appreciated.

Drive some wooden wedges between the pulley and the engine block as close to opposite each other as you can. Now hold a socket (that will just fit through the bore of the pulley) on the end of the crankshaft and give it a good whack with a hammer.

I would use some penetrating oil like liquid wrench over night. Then try using the bolt to tighten it then loosen it then tighten it then loosen it etc., to see if I could not get a little more movement.

also, I think you want the jaws facing in, not out.

Heat cool oil , heat cool oil, heat cool oil, heat cool oil, heat cool oil.

Use a 50-50 mix of ATF and acetone for oil

Heat for 60 seconds on high propane blast or mapp gas.

Cool for an hour

try the method suggested by wild things,you can also use your puller in combination with the wood wedges,and smack the puller screw,being careful to protect the crank shaft end.it's the smack that pops it free.

I use an air chisel with a blunt rod in the center of the bolt hole to "shock" the crank. I have a second person try to wiggle the pulley off with two large levers. Be careful not to booger up the threads.

I've seen those bend the hub on a badly seized pulley. But then I guess you're not gonna reuse it anyway.

If you heat cool oil is it still considered “cool oil”?

I've had really good luck with this type of Penetrating Oil/Loosener.
Seems like a Gimmick, but isn't. There are other brands out there selling the same stuff, so I guess the Formula isn't under a Patent anymore.
Word of warning ,it does smell a bit, use with good ventilation.
I consider it my Hail Mary type stuff for very rusted items, just follow the directions for the amount of time required for the spray ON.

I broke several exhaust studs on a sports car. A friend, an automotive machinist, who it went to, to drill the broken studs out, handed me a can of Liquid Wrench, and told me to put it on it, go get lunch, come back and see it the remnants would come out. They came out by hand. Many of these oils have chemicals in them that change the rust form from red to black. The black form of rust is a smaller molecule, and less binding than the red version. Kroil, PB Blaster, Liquid Wrench, and many more - they all work well. Some folks try WD-40 but is is not a lubricant. It is mostly solvent like a parts washer with some oils and things that help keep flash rust away.
