    I think I can see some dust. There must be dust - is that a hair?

    Jealous.

    Ignoring the playful antics of the more experienced members - I will continue the process.

    Disconnect battery - I repeat - disconnect battery.

    Remove primary drain bolt and washer to drain primary case - I put my bike on a portable lift to keep it straight and left it overnight. In the meantime I removed the derby cover, footrest, gear lever and primary chain inspection cover. Pictures show location of drain hole and magnetic bolt + nylon washer.

    Note filings on magnet and nylon washer. Both are effective components.

    Large phillips used for inspection cover - impact is not necessary and should be avoided if possible.

    Cover is removed from spline complete with footrest mount and bushing. Mine had loads of gasket sealant and was slightly reluctant. I am guessing the previous person reused the gasket along with extra sealant. I used a plastic "thing" to get it off.

    Mine's not that light, but I'm used to hydraulic. Hopefully, will improve with more use.

    Non standard bolts removed - shorter than standard. These will be replaced with OE spec. See part numbers above.

    After removing bolts the cover was loose. I did not use any force to remove the cover - just gave it a tap with a rubber mallet and a gentle nudge with a driver.

    Cover removed shows from the left - compensator, primary chain adjuster, clutch and starter pinion gear. The pinion gear shaft sits in a needle roller bearing in the cover and has a thrust washer on the end - 31502-65. Mine shows damage - the starter has not been engaging correctly and this is evidence of that problem. Further investigation is required.

    7/16 quarter turns until loose (no pressure on plate) one bolt already felt loose. The others were dragging on the loctite. I did them evenly and slowly at first and then speeded up with a ratchet.

    The top left bolt mounting on the hub is broken. I thought it felt loose!

    I have to ask myself if I snapped it off, but it did not appear to resist like the others + it's only blue loctite. The question is - Can it be repaired or do I need a new one?

    Re: Shovelhead Primary (FXEF late 84)

    Looks like a guide for the outer plate, and an old brake. If you have the broken part, (I'm seeing that you have) any half decent welder should be able to re-attach. A new clutch part might prove more difficult to source and more expensive. Not the end of the world, and sometimes expected from previous owners.

    Re: Shovelhead Primary (FXEF late 84)

    Thanks Simon, getting it repaired was my line of thought. The adjuster settings are fixed so it will have to be accurate.
