Re: Can't get crank pulley off...
Once the bolt is removed, you should be able to pull the crankshaft
pulley off - the section of crank which fits inside the pulley is not very
long. On my '91 200q, a green threadlocking compound had been applied to the
crankshaft nose to lock the pulley in place, but I was able to get the
pulley off by hand without too much problem. I believe this threadlocker is
a factory application, so if your belt is original your pulley may also have
the threadlocker holding the pulley and crank together.
The only way to break this stuff is to apply a shear force (which you
did with the puller) or to weaken it with heat. If you use heat, be very
careful with the rubber in the harmonic balancer. You might be able to heat
the pulley core with a hot air gun and then try your puller again. Make sure
you pull on the center core (if possible). If you pull on the outer rim of
the pulley you may shear off the rubber isolating ring inside the pulley -
the flexible rubber will also reduce the effect of the puller.
You could also try spraying a penetrating oil on the pulley/crank joint.
Does it look like the joint may be rusted together? This would make it
difficult to get off.
Good luck! Let us know how you make out - I'm sure someone else has/will run
into this problem.
