Re: crankshaft pulley removal

Frank,

The crank is not, at that point, tapered. So, in theory, the pulley should
just pull off. However, as we all know, the best laid plans of mice and
men...

I doubt you'll bend the pulley. It's cast so is more likely to break before
bending. I would also be wary of using levers. The thing you're levering on
is most likely the timing cover, which is cast alloy, and also likely to
break.

When I last did this, I put a bit of about 1' of 1x1 behind the pulley, and,
using both hands, used it like a slide hammer through the grill.
Fortunately, my pulley wasn't stuck. However, had it been, I was planning to
make up a wooden frame to fit behind the pulley and to get a hub puller to
pull on that (the idea being to spread the load of the 'pull' across the
rear face of the pulley).

Hope that helps.

Ross
