Just had the smog pump seize- I know, how odd . So I have the thing apart and wondering how I remove the "bad stuff" and turn it into a fan belt tensioner. Excuse my lack of terminology, but I am looking at a rotating "barrel" on the inside with the allen bolts holding the housing for the bearing as well as the "barrel". BTW it is full of grit, grease and rust- mainly accumulated power steering fluid. Thanks.
