    There were actually several because there were a couple different versions of the bolt. The early 256-14991-00-00 version had a screwdriver slot across the head. These came on carbs up to about '77 .....

    The plain head bolt used from '78 through '80 has a couple different numbers, don't know why. They would be 1A0- or 1A8-14991-00-00 .....

    Thanks for the advice and the parts #s !!!
    Found 2 of the plugs 1A8-14991-00-00 on Ebay for $9.19 each and only $5.00 shipping
    And got 2 of the copper gaskets from Partzilla (Of course there shipping is outrageous )
    Thanks again

    Shift shaft seals and bushings came in today
    This process went quite well using brass washers and a socket extension
    I thought I read here somewhere to use petroleum free grease as the lube when putting them in but then I thought there in place to stop oil from leaking out (so regular grease it was)
    I also saw in other posts where the seal had a spring in the seal
    These didn't ? Neither new or replacement And I also thought that the seal would be a really tight seal on the shaft too as in really need to push it in ? IMG_20210913_152452682.jpg IMG_20210913_154037176.jpg IMG_20210913_154113583.jpg IMG_20210913_154544561.jpg IMG_20210913_162810964.jpg
    Anyway score one for the parts replacer :cheers:

    Niche cycle gave me no hassle refund for the drain plugs I bought that were wrong
    I'm impressed another site bookmarked for me

    Actually, many of us apply Yamabond to the O.D. of our seals. This lubes it for install as grease would but has the added benefit of helping to seal it into the case .....

    Then, before inserting the pushrod, you can fill the seal lips with grease .....

    good work. I suggest polishing the old shaft......... Chuck it in a drill, rubbing compound on a rag.

    After a 4 hr lunch with friends ( you'd think we'd run out of BS after 2)
    Back at the bike minor progress /shift shaft seal done /chains back on and safety wired ( That little chain link clip pliers is great!)
    Front sprocket nut is back on ( I just hammered it on with a electric HF impact gun ) I think it will be tight enough
    Next parts replacer question As long as I have the side cover off I thought I might as well clean the rotor a bit
    THE 2 Screws are on tighter than shit but I have the Impacta JES screw driver that should take them out by just putting the screw driver in the screw and whackin it with a hammer ( It supposedly turns it just a fraction loose at each hit ) Each screw was wacked dozen times
    Any other suggestions maybe a little heat from a hair dryer on the screws ? Better impact tool ( I have a bigger toolbox so I got room for more tools)
    Anyway a few small /minor victories for the parts replacer :smoke:

    #3 bit!!!! A #2 will f'k the screw heads. Not sure what you have there? a hand impact wrench usually looks like this.

    On #3 good ole USA Phillips bits are "just fine" work perfectly. Other than that hammer away. Note when reinstalling; there is a pin in the crankcase at about 7 o:clock the stator has a slot that must sit over the pin. I use the impact hammer to lightly seat the screws "home". No need to go crazy on cleaning up the rotor face. 2M did some research and brush dust (graphite) on the rings actually improves the electrical connection 'tween rotor and brushes. If you just gotta clean; blue magic or some other metal polish is best, sand paper is too coarse.

    Yeah, I've dealt with them a couple of times and been impressed by their quick service and reasonable shipping.

    My impact is an old one with HUGE bits way to crude for this job
    I may just quit being anal about the rotor and move on it's not that bad or get another impact wrench that will handle the JIS bits that I have

    The Impacta really doesn't seem to be moving the screws at all

    A ramp type impact like pictured above sells for about $10.........
    Most impacts are 3/8" drive a 3/8" x whatever size your bits are 6 point socket would have you in business. (I do that fairly often, haven't broken a socket, yet)

    Yes, the drive size. I have several and while most are the 3/8" drive, I do have a 1/2" drive one as well. It works the best, better than the 3/8" drive ones. Most of mine are Vessels, picked up used and dirt cheap off eBay. These are the "Cadillac" of hand held impacts in my opinion and, in fact, I think they're the ones who invented the tool.

    Doesn't hurt to lube your impacts when you get them and every couple years or so. There's a ramp inside that works better when it's slippery

    And don't forget to twist it counterclockwise to "load it up against the ramp." If it's not, all your energy from the hammer will be wasted taking up all the internal slack, with nothing left to actually loosen the screw.
