    Default Cone Shovel Kickstart Tin Primary

    I want to dich the open chain drive and go with a belt. I want to use a tin primary cover, the cover with-out the big lump over the front pulley. Not really sure what I have here and what I will need.

    You will need a 1 1/2" belt drive, and an inner primary made for the alternator case. Paughco used to make them, and maybe they still do. That inner primary will accept any of the various style outer primaries available. It's a pretty simple set-up.

    You could also put the tin primary over your existing chain drive, if you use a solid motor sprocket in place of the compensating sprocket assembly that you have now.

    Still in their cat ..

    PN 754
    For the ‘Old School’ look on 1970–early 1984 engines when no electric start is used. Some spacing may be required between motor and inner primary. Takes the place of aluminum inner primary. For rigid frame use, but may also be used on swingarm.

    Boy are they proud of it, two bills, don't remember it being that spendy. Can I use an early outer cover with that, like PN 760?

    One other thing, I seem to remember having a short output shaft or some such on my Pan's transmission. Will I need that? Do I already have one?

    Paughco 750 will be a bolt on deal ...

    Pretty much any that are made for 36 and up Tin inner primary covers will work ...

    69 and back tranny mainshafts might be a problem (Causing alinement issues) .... That inner was designed for 70-up

    If you do use the 754 on a cone motor, you would need to use the 65-up eared tranny case with the 70-up mainshaft and a support bearing on the case ...

    Change one thing and 10 others will need to be changed to make that one work ..

    If your chain drive lines up, the new belt drive will as well. You don't need to worry about the shaft lengths.

    His chain will not line up ...
    Motor is a 70 up cone (Alternator)
    Tranny is a 64 and back ...

    Be 3/8" difference between the year models ...

    Will cross that bridge when I come to it I suppose.

    That cover is bad ass, but out of my league price-wise.

    Well Jesse you have an eagle eye. Yes there is a bearing support.

    I bought a Primo Rivera belt drive from you about ten years ago for a Panhead was a real nice piece.

    Looks like it. I sorta fell into this bike, I don't even know if it runs yet. I have some other projects in line ahead of it, but when the time comes, I'll get with you on a belt drive. Thanks for all the help fellas!
