    Scott, what kind of torque wrench are you using? Is it a dial type?

    Snoman, measure your washer thickness. When I changed from Riva coated to Jerry's I had only 75 inlbs. with the Riva's. They measured .081 thick. When I checked Jerry's 1 was .083 and 1 was .095 thick. I had to pm Jerry because I thought I had a bad washer because I was at 250 inlbs. Jerry to told me to sand a little off (very little)the L ring washer next to the nut. That brought me down to 180 inlbs. That was with a couple little strokes on some fine emory cloth. I checked it the other day after 4 or 5 hours and it is at 150 inlbs. The rest of the parts on my sc have 30 hours on them.
    Hope this helps.

    if you put 22ft lbs on a supercharger nut, ok that is telling you its tight, it does not put the required load on your clutch, thats why you have to test then re tighten, add shims if necc

    No way after ten hours. Did you try turning it a few rotations before checking the slip moment? If you installed the new spring washers you should not have needed to shim on top of that. I didnt bother to check what mine was after the last install. I just popped in the new spring washers and ran it. RPM's came right back up. Try rotating it with a ratchet 8-10 times and rechecking.

    here is something that can change also and you will never know! the base that everything sits on. meaning the colar on the shaft can wear also. you cant really see it but it does wear! and these guys are right abouthte spring thickness measure each washer and make sure its very close to the next one. some of these washers are not the same fromt e factory!

    but a quick question for all you who have seen this.

    I study what comes out of my race ski really good to see any changes form before.

    saw this ????????????????????

    the hole in the 06 shaft has a hole it it like allthe others, but there is a colar in that shaft that has the same oiler hole. mine has slipped and only half of the hole os open for the roller bearings to get oil!

    who else has seen this!
