One of the three “dogbone” springs on my pulley looks to be bent in an extended position. Anyone have any thoughts about how I might go about fixing this?
I am pretty sure it happened when I recently swapped the bearing. I could not get the old bearing out, so I had to take the pulley to a shop with a hydraulic press, and I’m guessing they weren’t careful.
The car drives fine but I imagine it has the effect of keeping the supercharger engaged all the time, because the pulley won’t spin free of the clutch assembly.
Buy a new pulley before that breaks and ruins your hood and oil filter housing. I would take the belt off if you don’t have another ride and have to go somewhere.
let me know if you want a stock pulley, I have one I just took off my car at 98K miles, it is in good working order, I replaced the bearing about 12K miles ago

I've been digging through these old posts and I did the same thing on my own press. I should have placed the face of the pulley where it is angled between the slot for the bearing and the outside for the belt face down the press. There is enough room on the ridge and it is strong enough to allow you to press the bearing out. Eventually that is what I did but I messed it up and it wound up costing me $434 as I ordered a 88mm pulley from UPD as it is slightly smaller and lighter but doesn't require any tune. The bearing wasn't *too* bad in mine so I'm kicking myself a bit, but I'll get over it.
I removed the bearing from the pulley again and am going to save it as I didn't use the hammer method and it will still be fine for reuse at some point later in the future. These are the type of mistakes that one hopes to avoid but sometimes no amount of trolling through these forums for gathering information can prevent them.
