Can't open a Comet 40 series for cleaning

[DFWRealist]

Hey guys....

I bought a Manco SuperDeuce with a Comet 40 series torque converter.
I checked YouTube to see how it comes apart and how to clean it but, no matter what I try... I simply have not been able to get it to come apart or even loose.

I have used a lot of penetrating oil, tried a pipe wrench with driver fixed in a vice and still... Nothing.
Here are a few pics I just took.
On the top, the 1 3/4" nut has two welds that look like they are holding it on.
I checked several pics online and some had the welds and some didn't.
Is that the problem?

Should I grind the welds away and after cleaning, re weld it?

Also, I haven't counted the teeth on the big sprocket on the axle but the jackshaft sprocket has 9 teeth.
What should the ratio be? I am putting in a new Predator 301cc engine.

Thanks!

Nope, leave the welds untouched..
(the only thing they do is stick the nut to the outer bell to not loose said nut as easily.. it's not really needed [hence chinese copies don't care] but it's what distinguishes original comets from clones rather easily)

And yes, if the rust on the backside is something to go by, you'll need a lot of patience and penetrating oil to get it loose

First: put it on an engine and secure it, spin it up and see if the inner sheave is still moving
if it is, it's indeed only the threads that are seized;
if it doesn't, chances are the moveable sheave itself is seized to the outer bell;
in that case, the seam between the outer bell and moveable sheave asks for penetrating oil as well

Outstanding! I just put it on the new engine to see what it would do... It seemed to spin and move as a torque converter is supposed to (It has all the surface rust still so, I didn't put a belt on it).
It slid all the way over when I revved engine to full throttle and smoothly moved back at idle.

So at this point... What should I do to get it loose?

What size is your axle? One inch? With a keyway? Slide the converter on the axle to hold the insides while you work on the outside with a pipe wrench.

Might need a shock with a hammer on the wrench.

Thank you, guys!
I got it loose and cleaned. It really needed it.

I ended up putting it in a vice and made a makeshift tool that fit in the bore and used a big air impact wrench. Took a minute but, it finally gave and it was easy from there.
