I don't know where you measured - the bolt comes out and don't forget
to take that big flat washer that's under the bolt out BEFORE you try
the puller! Once the bolt is out, there is a centering hole in the
end of the crank that the puller sits into. Mine is fairly long and
the 88 MJ is set up so that the puller screw rides just uder the
radiator. That means you are turning the puller with your knuckles
right next to the radiator - and that sucker can bite.

I drilled a couple of holes in a 3 foot piece of 5/16 bar stock I had
laying around and bolted that to 2 of the smaller (about 1/4 inch, but
metric 6-8 mm?) holes in the middle part of the damper. That rotated
over against the frame and held things nice and solid while I used a
big breaker bar and socket on the bolt. Same for touquing it back.
If you do use the puiller, be careful with the bolts that you use to
attach it to the damper. Mine were drilled all the way thru and if
the bolts are too long you can punch them into the timing cover.
That's a standard RH bolt, BTW. Also, it's a lot simpler to see what
you need to do if you parctice the setup on the new one to get an idea
of where all the holes are. DON'T FORGET THAT WASHER - someone here
worked for a considerable time before he got around to taking that
sucker out and was amazed how easy it was after that <g>.

Given a choice, I would have pulled the radiator and used an impact
wrench but every one I did had a/c so I would have had a skid plate
and the condensor to pull in addition to the radiator - easiler to
take a little time and make the holding tool.

Re: guess harmonic balancers don't last that long.
 

I will second that, some of those can be a real bugger to get off. I
have seen and heard of lots of broken pullers over the years.

To get the main bolt, you can use a long wrench braced against the frame
and the starter motor.

Basically if the pulley isn't wobbling and if the timing mark is still
correct, then I would leave it until I 'had' to take it off or something
else off.
