Do you have a slide hammer?

You said you tried a puller? Did u try the puller with an impact gun? The impact will help break rust lose.Pb blaster penetrates and creeps beter than wd40 in my world. There is a loctite spray that freezes down to -45 degrees so the parts contract to allow the penetrating oil to seep in easier. You can ge it at advance auto $16 a can. I can confirm that it works better than pb blaster on real tough stuck s**t. Aint cheap though.

Gotta take the front washer off first .... should have came off with the bolt.

No the puller wouldnt even fit the gap isnt big enough and yea the washer wont come off either and it sucks because everything is ready to be sent off but this is the only thing holding me back

Try a little heat?

Try a little heat?

Use a torch or what? and how would heat help the rust or whatever issue is present?

Maybe smak it a bit with a brass hammer, or put a chunk of wood on it and hit the wood with the hammer to jar the sprocket loose .
Heat expands things and frees things up to loosen-it can be a great ally in the toolbox .. a blowtorch.

^This, go rent one.

I had the same issue, screw in some bolts into the threaded holes on the sprocket, use the bolt heads as the lip for a gear puller to grab. It should come right off after you get rid of the washer. I also agree that some heat will work wonders.

Spray a little BP Blaster on it and let it soak in. Next, apply heat to the sprocket. Get it warm but do not get the front case oil seal hot. Take a brass hammer and tap around the sprocket. The impact will help break it loose. A slide hammer arms should fit around it, as stated, you can rent one. I have also put the harmonic balancer back on the crank, placed a short 2x4 on the front case and used a pry bar under the balancer to walk it off.
