I got the supercharger off tonight. Wasn't that bad to get off....no worse than an L36 upper intake.
I then went after the lower intake. Again, not much different than the L36 lower. The lower intake gaskets were rather deformed. But, not anything worse than I expected on a 14 year old car. Supercharger gasket was cracked in about a dozen pieces.
I got the nose drive off the supercharger on the bench. 3 of the 6 holes in the coupler are egg shaped. I assume that'* what was causing the rattling and slop in the pulley (when spun by hand).
Where can I get a replacement coupler? Advance, Napa, Murray'*, AutoZone, GM, and Canadian Supercharger don't sell just the coupler. And, when I do get the coupler, is it directional? I noticed there are shoulders on 3 of the 6 holes in the coupler. Does that shoulder have to ride on the posts in the nose drive or the supercharger? Or, does it not matter?
And...I noticed there wasn't much oil in the supercharger. It didn't stink bad, either. What did come out was clean. The rotors feel very tight. No slop at all. However, the filler plug is stripped. I assume it used to be a 4 or 5 mm allen head. Should a machine shop be able to tap a new one in there? ...any precautions I should know of before I ask them to do it? I figure it'll get drilled out, a helicoil installed, and a plug to match.
