I need help!
 

I'm rebuilding a 13b in my trans tech class. and i have one question
How do you get the huge socket or nut off?
It's the nut or socket that holds the flywheel on?

MazdaTrix has a BFW...big F'n wrench for that. It is actually cheaper than buying the huge 2.125" socket and 3/4 inch drive to run it. It also comes with a metal strap that you can drill 2 holes in so the flywheel will be more secure and not move. If your engine is like the last 2 I have done, you may want a sledge, aka BFH, to get more force on the big wrench. Hope this helps.... Mazdatrix part number is 49-22000 ~$36.

That pretty much answers it.... Big Mutha F*cking Wrench.

I may be very wrong but I believe it's something like 350 lb/ft of torque on it...
Just have some means to immobilize the flywheel.
