Accidentally bent drive pulley when trying to remove...

[RED-Z06 2,248]

Ive fought alot of these cast pulleys, i usually start with knock er loose about a half hour prior to loosen the set screws, rust.  Then once those are out; fill the holes with more knock er loose.  Then ill tap a couple chisels in behind the pulley, or flathead screwdrivers, just looking for slight outward pressure.  Ill put a drift of some type on tge crank end and give it a whack..the softer metal drift, such as brass, protects the crank.the slight crank endplay us your friend here, once its moving it when ill put a bit of heat on the pulley..nothing crazy, just looking for some expansion, they usually slip off.  Ive never broken a pulley but ive had many that were already broken...jaw pullers will do that

@Alrashid2  have a set screw on that  ?  KROIL  is the best lubrication  creeper ever , also like to remove set screw , and leave it at 12 o'clock , so you can refill  screw hole , inhance creep , this anything that I have had an issue with , do not expect an immediate response , do this on a area that you have access to , and is in use , kroil tracking is easy to follow , on a vibrating engine , would also favor  a very solid leverage attempt to start , when you can overpower a frozen pulley , with solid leverage , its strength against strength , a split  bearing puller , will probably do it , pete
