Give it a tap, hard ish on tbs side of the hub, it's a taper locking one so will pop , or a touch of heat
Whatever you do don't feck the thread in the end of the crank or its worth nothing but weigh in value
Heat, hammers and swearing didn't work. Finally got a 3ft bar on the puller and it went, firing it across the garage, out of the door, across the path, across the road and into someone's garden! Knock, knock, excuse me can I have my engine bit back please.
