12a flywheel bolt
 

12a guys is there a mazda order 54mm 3/8 socket, or what r u guys doing to get off the flywheel bolts? where could I order one?

Sears, it's also 2-1/8". That size socket takes a 3/4" drive, pick up the 3/4 to 1/2" adaptor. You will not get the flywheel nut off using 3/8" anything.

yeah no kidding, specially at 300 foot pounds.

Dont make the mistake of buying a 2 1/4, it works, but its sloppy.

you can order one at lordco, jet makes one for 50 dollars, my price was $30

yeah, that shit sucks the big one..i got mine off just using a basic impact..it took a minute, but it worked..haha, i just got done rebuilding a 12a..it was fun..

:AA:

if you dont hae an impact gun, mazdatrix sells(or you could make) a flywheel stopper that bolts to the block and prevents the flywheel from turning when you are trying to remove the flywheel. to me, it was worth the $20 i paid for it. its definatly paid for itself.

the 2 1/8 from sears works - about $28

When I was working on my 12A I got the 2 1/8" socket from Sears, and then also got this 3/4" Torque wrench for a steal off of E-bay. It is exactly like this one...

I was very surprised at the quality of the torque wrench. It works great, and I was sure that I had torqued down that dern flywheel nut the proper amount...

hammer and chisel. Buy yourself a 1/2 cold chisel and grind down the tip so you dont slice the flywheel nut. Small but very handy particularly in junkyards.

Heres my answer. https://www.rx7club.com/1st-generation-specific-1979-1985-18/flywheel-stopper-547683/

No need for a flywheel stopper IF you have a hammer and chisel.

I know that this is an old thread but i just got a 55mm socket, failed to read the fine print and its outside diameter was infact 55mm
