What kind of sound worn coupling/coupler in supercharger gives?
I have MPII supercharger that is driven about 4-5000 miles (+10% smaller pulley..)
It has been giving slight sound kinda like marbles rolling inside supercharger at idle.. noise goes away as revs go up... say few hundred rpm's. (or I can't hear it anymore)
Pulley in snout feels solid without any feeling that could indicate bearing failure..
Should I worry about this?
edit: I inspected supercharger oil month or 2 ago... there was guite lot of metal "dust" in it, so something is going on. I removed most of the oil and replaced it with clean one. Has worn coupler done this? (I have no idea if MPII has "rubber" or spring loaded version of coupler.)
