Hey guys, I'm thinking about picking up a set of UD pulleys and I'm wondering if I need any special tools for this job. I've heard you need some sort of puller to get the crank pulley off the motor but not sure if this is true or not. Any help would be appreciated.
The 4.6 motors need a puller as the harm. ball. is part of the pulley system. When we put UD on a buds 98 he got a new HB and we swapped them...needed a puller to do it.
On the 5.0 you just undo 4 bolts and you may have to tap or knock the old one off it its crusted on but its a simple unbolt/bolt on.
Thats a nice gain for pulleys. I only gained about .1, Don't even have them on my car anymore. Had to remove them to solve an issue with the belt rubbing itself after I removed my ac and smog pump.
