Wow, I can't believe it could be that difficult to remove = a pulley!  Is there a way to know when I put the pulley back in, = whether those thrust races moved and will therefore be messed up or no= t?

I guess I'm going to have to get= my Haynes book out and see if there is a schematic which shows what you're= talking about.  So if you ever need to pull that pulley you have to b= asically pull the engine and stand it on end?!  Surely the Mazda engin= eers could have come up with a better mouse trap to preclude having to= do that; couldn't they???
=0A

One other quest= ion; as you know I have one of the bed mounts that Fred Breese actually del= ivered and I am getting close to the point where I'm going to want to mount= the engine on it and not pull it off again.  I went to the Mazda deal= er in Norman and paid some crazy money $19 or so each for the stock oil pan= gaskets (one for each side).  I now am wondering if I should just use= some ultra grey permatex as I have seen some guys mention on the newsgroup= ; or what about running some silk thread down both sides of halves&nbs= p;(like I learned at my A&P some years ago) just like when yo= u put Lycoming case halves back together after a tear down...
