You are most welcome Steve.
Yes, the crank timing belt pulley gave me a hard time too
This was the way I removed the one from the 2 litre Pinto that I have just stripped.
Once the alternator belt pulley was removed I cleaned the nose of the crank shaft with some fine abrasive paper ( Just enough to remove the worst of the surface crud )
Once nice & clean I grabbed my small plumbing blow lamp & warmed up the pulley, concentrating the heat on the pulley & taking great care to avoid heating the crank itself. ( It'll help if you can rotate the crank whilst you are doing this )
No need to go stupid mental with the heat, the pulley should expand a little quite quickly.
Just hot enough to make you say " Ouch that burnt my friggin fingers " when touched.
Once nicely warmed up, put the blow lamp to one side & squirt some easing oil on the pulley ( Put plenty on there, it will soon work its way under the pulley onto the surface of the crank)
Once nicely lubricated put the heat back onto the pulley & warm up once again ( Again, turning the crank if you can )
When warm enough turn off the heat & grab a couple of large flat screwdrivers/flat levers & gently lever on the back of the pulley, if done evenly the pulley should start to move & will most likely ease its way off.
If you only have One screwdriver/lever just keep rotating the crank & gently lever the pulley a bit at a time.
Once it has moved enough onto the clean face of the crank the pulley should come off more easily.
In an ideal world A slide hammer & pullers would be the tool to use but how many of us have one of those in the tool box.
If you don't go stupid with the heat, no harm will come to the pulley or crank .... Dull Red, means you have gone absolutely mental with the heat,
that said you'll have a job to get that much heat with a small blow lamp.
