36mm.  This is a good excuse to get a 1/2" socket wrench with a 16" (?, it's
long) handle and adjustable head ;)  You will need an extension since it's
deep in there.

Hmm, one of my shop manuals said it could be pulled straight off but didn't
specifically mention a puller.  I believe the Bentley said to use a puller.
it doesn't come right off then use a puller (you'll probably need one).  Is
an ambiguous enough answer for you??

You will need a torque wrench for tightening the bolt properly.  Also, there
a paper shim (gasket) that fits between the pulley fan and its seat.  I
know about the early models, but mine had a dowel in the mating surface so
fan could be placed exactly back.  Mark your pulley fan against the crank
with a
grease pencil (China marker) just in case.  This is especially important if
had your engine balanced!

I know for me that getting the bolt out with the engine in the car is
since my bolt is Loc-Tite'd in there at 125-ft/lbs (NOT recommended for a
engine!).  I made a pulley lock and you can see it on my Type Three Tech
(http://www.geocities.com/MotorCity/Speedway/1641/ ,about mid-page).  If you
make something like it, it will definitely help.  You DON'T want to use a
or wrench or screwdriver wedged in there to hold you pulley fan since you
have a
very good opportunity for chipping the fan blades.  Trust me.
