I got an m90 about a month ago but the rotor case was damaged in shipping. NBD, I got a refund. So I got a different rotor case to swap. Swapped them today. Undid the bolts and hammered on the case to get it loose. Then used a crow bar to start lifting th snout and rotors out. I placed the assembly on my benched and, about 5 minutes later, noticed alot of oil leaking. So I'll need new supercharger oil I guess. The bearings on the new rotor case were not in as good condition as I thought. The little rubber seal was deteriorating. So, I took the bearings out of my new one (used a socket to hammer them out, no damage). But ended up going to "All Star Auto Parts" in Redlands, CA to have them install the bearings. I didn't want to mess that up. I read that some high temp wheel bearing grease would work fine for this application so that's what I used to re-grease. Put it all back together. Only used 4 bolts though. I originally was missing two but decided to not put all of them back since I'll need to take it apart to put oil anyway. So if anyone would like to give me any pointers or suggestion for this restoration, that would be great
