    Mine has started leaking oil from the disc fitted opposite the cable end.

    Has anyone taken one of these apart? What is involved in a rebuild? Are parts available and from where?

    It seems to me, these things should have a grease zert fitted, but they don't.

    Well, the Norton Gremlins struck, and i am forced to address this issue.

    I tached up the Atlas this evening and the tach suddenly dropped to zero. After reaching home I checked the cable at the tach and tach drive ends .... each was fine, but I found the sealing disc on the drive was gone, along with the gear that is driven by the camshaft.
    Walking up and down the highway in search of the missing parts was fruitless.

    An eBay search reveals the gear is available from an aftermarket supplier. I cannot find the sealing disc ..... anyone know part number or supplier?

    Slick
