Hello out there!

My '82 Westy has developed a bad oil drip (qt per 150-200 miles, I
suspect it is the main seal behind the alt. pulley.

The manual shows using a puller to remove the part which carries the
pulley but does not mention how the pulley comes off.  I tried moderate
force but cannot loosen the pulley.  

Is there something obvious I am overlooking?

Thanks,
