Just bought an 88 B2200 but the crank pulley wobbles. I replaced it with another pulley and it wobbles just as bad.

So the pulley is not the problem. Could the crank be bent? it still drives and runs good once its warm. has a problem starting but thats another topic.

What else could it be? I dont know how the crank could be bent. the guy said it was never in a front end accident and there are no signs of on. I really dont want to sell the truck but time is short.

 

Maybe both pulleys are bad. Is there a woodruff key?
