Seized 1973 400 cu in

[PERoss73Sat]

I bought a 70 Satellite Sebring with a seized engine. I put a mixture of ATF and Marvel mystery oil in each cylinder. I want to get a socket on the main bolt in the front to rock the engine with some leverage to get it loose. I can't find the right size socket. I tried 1 and 1/16 and 1 and 1/8 and both were too small. I also have a 32mm socket which was too big. How can I find out what size that bolt head is?

1 1/4..

1 1/4..

Thanks!

32 mm is 1.25"

32 mm is 1.25"

The 32 is slightly bigger at 1.26". Kinda like yards and meters

 

[RemCharger]

Technically it's 98 ten thousandths of an inch bigger. So while it's less than blonde c- hair, it's still not  exactly the same. I agree.

 

[dadsbee]

Probably more like a Brunetts c hair.. but ya. If it's a 6 point should be zero issue...

This above and/or how worn it is. Trying to break that thing loose, not gonna work most likely

I'm seeing about 45 thou on the 1 1/4, and about 50 on the 32.

Or how rusty the bolt is.....I mean cap screw

 

[RemCharger]

Wow.

I suppose to answer the question properly, a guy could take it down to a machine shop and have the head examined and measured.

I'm afraid you're right, but hope springs eternal that those extra 10,000ths might make the difference. Otherwise I gotta save my pennies for a new engine.

If the engine is out instead of doing it by the crank bolt you can use the flex plate. I have seen people weld straps on the flex plate close to the bolt holes so you can slide a pipe in and use a pipe to break it free. It was on an engine dolly...

its even easier if you use the old torque converter/leave it bolted to the flex plate/and then use a Large Long breaker bar inserted into the vertor Slot/snout Sideways to move the crank back and forth.

to the Op,make sure the plugs are all out and cylinders have oil or tranny fluid in them to soak.

I got it loose with equal parts ATF and Marvel Miracle oil and a long breaker bar. Took a couple weeks of soaking and a lot of wiggling.

People always tell ME to have my head examined....
