Continuing with the original question in this thread: LOOKING FOR SMART WRENCHER to answer what exactly could I have f—ed up by using heat to break this nut free?
Son and I took off his front transmission pulley yesterday and absolutely had to use heat - even with the locking tool and a four foot breaker bar.
I used map gas and applied at least 60 seconds of steady heat. Didn’t cherry it, but she got hot!

Hey, you will not have damaged anything. These suckers are just so tight.
I had to loosen mine , fought with it for 4 hours.
Breakerbar, socket , etc.. all . No success . Even got my fingers hurt when the socket slipper off. Don't ask.
Was sick of it. And went next morning to the hardware store. Bought an electric impact hammer. Took literally 5 second to loosen the nut.
To reinforce : get the right tools to get the job done. Old saying.

Interesting responses... I'm talking about the transmission sprocket on a 6-speed '09 Street Bob. Page 5-18 of my service manual covers removal of the transmission sprocket. It shows using the special tool I just ordered. It says :
5. Remove transmission sprocket
a. See figure 5-39. Remove 2 screws and lockplate. (I looked at the figure and it looks exactly like what I see on my bike. I removed the 2 screws and the lockplate.)
b. See figure 5-40. Secure sprocket using FINAL DRIVE SPROCKET LOCKING TOOL. ...
NOTE: Sprocket nut has a right-hand thread. (it actually has right-hand in bold).
c. Install PILOT (this came with the special tool) on mainshaft.
d. Remove the sprocket nut using MAINSHAFT LOCKNUT WRENCH.
So my service manual CLEARLY STATES that this is a right-hand thread. This is going to **** ME OFF if I find out the service manual is wrong. Can someone else look in the service manual and verify what I'm saying is true? The link that was given above shows someone removing the nut on a '02 Ultra Classic. My bike is an '09 Dyna Street Bob. I'm REALLY WONDERING about whether or not this is right or left-hand thread but my service manual DOES say right hand and I'm not confusing this with the clutch hub nut. My clutch hub is on the floor and the inner primary is already off. Thanks for any further input.

At least ones I worked on.

Nice underhanded cut and paste.
Here are the actual posts from that thread:
