Dale, not sure if this went through so I'm sending it again. (incase you get
deja vou reading it).


Dale,
You will also need the counter weight based on which rotors you have (year
and turbo/na).  I haven't seen these on e-bay which is surprising because
they really should go with the flex plates.  I guess people are keeping them
with the engines because it will require removing the e-shaft nut.  Besides
the counter weight, you will need a bunch a metric bolts to attach the flex
plate to the counter weight, a flange (crush plate looking washer), and an
e-shaft nut.

To tighten the e-shaft nut you will need the proper sized (very big) socket
(I forget the size you can find that on the mazdatrix web site).  I got a
socket from McMaster Carr for about $30.

You will also need some way to keep the e-shaft still while tightening.
Mazdatrix sells a tool that works OK, or you can make a breaker bar.  Be
careful, I almost ruined my flex plate trying to use a home-made breaker
bar.  The flywheel is much more amenable to a home made breaker bar than the
flex plates.

Good Luck,
Dave Leonard


Hi All,

   Okay, now the "newbie" in me is really going to show.
Earlier in the year I picked up an engine - for a rather
"friendly" price.  As time has gone along, I'm finding
more a more things that I missed on the pre-purchase
inspection.  I still got a good deal for a "bare block",
but now I'm having to find parts "blind".  I don't know
what they're supposed to look like.

   The flywheel end of my eccentric shaft is just a taper
with a key.  So I'm missing some sort of a hub upon which
my new flexplate (Thanks, Dave L.!) is supposed to mount.
My handy-dandy Chilton manual yields not a clue.  Yeah, I
know, I need to stop at Checker and pickup the Haynes
book.

   So, before I start searching the local Mazda dealer
for parts and pieces, I need to know if I even got a
useable flex plate. Here are two photos of my "new" part.
Can someone tell me if I got the right one for 86-88?  Or
how to identify it?  And how to indentify the counter-
weight?  The torque converter mount holes are about 1-9/32"
apart.

ADVthanksANCE,
