Another alternative is to use a hand impact tool. Only downsize is it will put stress on the countershaft bearing. If you’re willing to go this route; HF sells them. Make sure to get the 1/2’ drive set. That way you can use an impact socket. Good luck!
Link to the HF hand impact. These come in handy for other jobs too.

I do actually already have that, I was using it previouosly to deal with ancient screws that i'm worried about stripping out.
Does that actually have a better chance at working than a power tool?

Got a Harbor Freight near you? If not- Amazon or Ebay will work... or you can probably find something used that will do the job on your local Facebook Marketplace or Craig's List..
unfortunately, for the money any new tool will cost me I could just about pay the shop an hour of labor to swap it out for me, which It looks like is exactly what's going to happen. I'd rather do that than risk making it worse with my continued fumbling.

Useful to know RedB.

This is actually the second time ive changed a front sprocket. It was hard but it moved the first time. This time its like its welded on.
Have you considered if its a reverse thread?
Left hand threads are common on spining things!
RE: Front sprocket bolt cant be moved - misterprofessionality - 03-09-2023
I don't think I've ever heard of a front sprocket like this having a reverse thread....the first time I removed it i don't believe it had a reverse thread. if anybody else can confirm that or tell me different i'll take the L, but i'm pretty certain it doesn't have a reverse thread.

Service manual torque table says: thread dia. 10mm, torque 40 lbf.ft and the remarks column is empty. The later means it’s not a left handed thread. Also not word one on “being left” on page 3-21.
Of course jto is right with his remark BUT it’s a matter from where you look. When our engine pulls the sprocket forward (call this a right turn as seen from the inside) it tightens the screw.

You've had it off before? The plot thickens...
Did you tq to spec upon reassembly?
40lb/ft is half of what I tq my lug nuts to.
RE: Front sprocket bolt cant be moved - misterprofessionality - 03-09-2023
I did, assuming i used the torque wrench correctly. that was maybe 4 years ago now though.

Usually left hand threads are on a right hand side chain front sprocket.
