    I have a KH/Onza 05 hub and crank set and I was cleaning it. Everything
    went fine until I got to the inside of the crank.

    1. There is that big bolt inside keeping me from cleaning the splines.
    Any ideas how I can clean in there? (I also need to put grease back
    in)

    2. The "split washer" is inside the crank and I want to get it out to
    clean it. Any ideas on how to do this?

    3. The "ring-shaped bolt", pinch bolt or what ever that piece on the
    end of the crank is called won't come off. How do you take this off? I
    putting allen/hex keys in the holes and tried to “turn” (more like pull
    with all my strength) the doughnut shaped “bolt” in a clockwise
    direction. I couldn’t get it to turn.

    4. This 'site' (http://www.krisholm.com/techsupport/hubassembly) tells
    the order that the pieces go on the hub. I took off all these pieces. I
    also took off a small metal washer/shim/spacer. This piece is really
    small. I don't remember where it went on the hub (I.E. after the bearing
    but before the thingamajig) and the site doesn't say as far as I can
    tell. Do you guys know where it goes?

    5. I’ve taken off all the grease. When I put the grease back on I want
    to put it on all the surfaces that touch another surface right?

    6. Do I put grease on the outer rim of the bearing that sits in the
    bearing holders and frame?

    7. Any other tips on greasing, cleaning, reassembly, and pinch bolts
    would be nice.

    Thanks j45

    I'm unsure about any of the other questions, but I think I know the
    answer to question 4. From memory, the really thin spacer goes in
    between the cranks and part F of the diagram. It sort of rests on the
    splines and is the last thing to go on before the cranks.

    I'd be interested in an answer to question 3 as well. Previous
    unicyclist.com posts indicate that the ring thing on the end is a dust
    cap and can be removed with a pin spanner. Its threads are left-handed
    (opposite of normal). (That was also from memory.) I assume the answers
    to 1 and 2 are obvious once you solve 3. In my case, a cursory effort
    did not remove it and I haven't cared enough since then to try harder.

    jeez man, how did this get so burried? this forum was once full of tech
    help, now its mostly boasting of personal drama, sarcasm then
    applause.

    anyway, i got my crappy camera and went the inlaws house to post some
    help for you.

    what you do in fact need is a pin spanner, the one i have is made by
    Park Tools.

    Kris needs to change what he says about using a allen wrench to tighten
    the caps. it is both the wrong tool for the job and wont get it tight
    enough.

    This is a good diagram someone posted before. I think it was Roger at
    UDC.

    That's what Kris says about getting off split washers:

    As you say, the split washer is stuck inside the crank when you take the
    crank off. After you unscrew the ring washer on the outside of the
    crank arm, just take a flat-head screwdriver and use it to gently tap
    the split washer out of the crank.

    Though: Mine seems to be stuck.
