I have had some luck with this problem.
I decide to get the impact wrench at Sears this past weekend. This was after I had tried a few different methods to remove the clutch with no success. Like may dad says "you can never have too many tools". I have been wanting to get one of these anyway.
I got an air powered 400 ft/lbs Craftsman and it is a solid unit.
I had never used one before so I was curious what would happen.
When it first spun the nut, the bell housing went with it, but it quickly loosened the nut and off she came.
I used some Emory cloth to buff the inside of the bell housing and the clutch pads, which were glazed a bit. May I add that these are some wimpy looking pads on the stock unit.
I cleaned the dust off the parts and put it back on the bike. I used the impact wrench to tighten the nut.
I test drove it after this and was not overly impressed, but on my ride to work today, I was. There is much less "slipping" and the scooter seems to have better pick up.
Has anyone installed a "performance" or "racing" clutch on their Super 8? After seeing what the stock looked like, I may want to upgrade.
