Does anyone have a trick for removing a flywheel. The nut is off abd I
tried using the holes close to where the shaft comes
through by tapping
them for2-  3/8 -28 bolts and part of a puller the
screw.  After 3
attempts I pulled the 3/8-28 screw right out of the
flywheel.  I thought
about making a puller out of the old clutch but i
have to find some
steel that won't buckle.  I have numerous pieces of
channel and U chanel
that are twisted up beyond recognition. Thanks for
any help

You are not the only one with the twisted channel :)
Brute force. Once you have the nut off smack the
flywheel with
a ten pound sledge hammer as shown in this pic. It
will pop
right off. You won't hurt the e-shaft.

I just went thru this a couple weeks ago. I heated
the fw around the shaft with a propane torch. Then put
some preloading force on the outer rim with a lever
using the side housing as a fulcrum. A couple hits
with a mallet did the job. BTW those 2 holes in the fw
are already threaded for a metric bolt on mine. I had
a much worse problem getting the front e shaft bolt
out. Even broke a cheap socket.

Break the front bolt loose first with a tool
from Mazda that locks the flywheel. Then remove the flywheel
nut and flywheel. No need for heat. Just smack it with a large
enough hammer. A carpenters claw hammer is not heavy enough.
