installing new SC, can't get the M7 pulley of the old SC
Hi everyone,
Well my title is my question. My wife broke down 250 miles away from home, and it was the supercharger seizing at 105 miles. I just changed the oil in it 10k miles ago, so I guess when the seals go, they go regardless of oil quantity or quality. I did hear an odd rattle as she drove off on her trip, and noticed that it stopped burning a small amount of oil, which had been visible out the tail pipe. I should have done the math..
I am in luck and have a spare supercharger on the shelf (we both drive r53/52 with 105k)
I'm hoping to transfer the m7 pulley over, but I can't pull it off after removing the 4 bolts. I heated it with a torch and very lightly pried to see if I could separate the two halves, but not a budge.
Any tips, or will I be buying a new pulley ? :-)

my suggestion....
hit the bolts on the pulley with a bit of HEAT...
they are USUALLY put on with some LOCKTITE (if a pro did the install)...and heat can soften it a bit....
Carefull....too much can go up the shaft and cook the seal on the SC...then again..it is junk....and will be replaced IF you decide to rebuild it.

got it!
Hi guys. Thanks for the responses. It turns out it was much more simple (in theory) than I was making it. On the M7 pulley, there are two extra holes, that looked smooth on the inside to my aging eyes. These actually have threads, and allow bolts to be threaded down to pop the two halves apart.
No, they didn't pop apart right away. Yes I twisted an allen key.. then out came the trusty torch. There was no chance in rebuilding this sc since the lobes seized. The torch worked wonders.
Car is now back on the road! Now I need to figure out which wheel speed sensor is causing my triple light dilemma. Maybe I'll just change all 4...
