    Default Replacing clutch on the Sporty

    Late model Sportsters have developed a reputation for a clutch failure that is sudden and fairly catastrophic. In the center of the clutch pack is a double steel riveted together with flat springs between. It softens the clutch engagement I understand. Unfortunately it also fails, filling the basket with the brass rivets and springs, sometimes even the steel plates break. I am sure it is uncommon, but several posts about it on the XLForum convinced me to change mine as a preventative measure.

    I am waiting for the brown truck to show up with my Energy One extra plate kit. All the clutch makers offer a kit to eliminate the spring plate by adding 2 steels and another friction. Maybe it is to add grip, as the stock clutch is only good to about 85 hp? Maybe it's because of the problems?

    Up on the table


    Off with the primary cover!


    So that's what's in there!


    My high tech clutch spring compressor. Saved me $45 to $100.....


    Yeap, it worked!



    The infamous spring plate...mine looks fine to me.


    but, the frictions on either side of it were worn like they don't apply pressure evenly?


    I suppose they would have lasted another few thousand miles, but this wear might be the cause of failures? There would be metal to metal contact here soon.

    The primary chain tension adjuster was pretty worn, I replaced it. Less than $25, amazing! (Less than the gasket.)


    More when the kit arrives!

    Two words for you sprinkster: MUFFIN PAN

    Gasman can tell you the importance of magnetic muffin pans and how they work. And he uses one for self defense.

    Bonus points for the high tech spring compressor.

    Give me a call when you get that done I will drop off the R1 for full suspension, slipper clutch and valve rebuild. Thanks.
