    Hey Guru's
    I need to replace all the washers in my foot pegs as some how they are all wrong. I am trying to source locally and can you decifier the washer size from the part number? 9020110437 is the number so would it be 11mm id and 37mm od with a 4mm thickness.
    Glad to see all the Northern brothers getting out and putting miles on seeing it summer. Winter down here and raining for days!

    As far as I know, you cannot decipher washer size from the part number like you often can for bolts and screws. In your case, the 37mm od and the 4mm thickness are way too big.
    I measured a couple of my footpeg washers, and I think the correct size should be 10.5mm id, 24mm od, and 2mm thickness.

    As another example, here are the part numbers for 70, 71, and 72 footpeg washers from the parts diagram. The actual washer sizes in parentheses has no relationship to the parts number.

    If you're looking for some originals, they're easy to identify because they have the letter "B" stamped on them .....

    Holy cow - how the heck do these guys know this stuff?

    Anyhow - OEM part numbers very seldom convey anything about the physical characteristics of the part. They really are just an organizational tool to help keep track of bits and pieces.

    In most companies, the first few digits may indicate a part family (such as vehicle model or engine series) - and then the rest of the number is simply released sequentially as the part is designed or specified and ordered from an external supplier. For example, most late series XS650 parts begin with "447-" and this is the engine type of the post-1973 (i.e. 74-onwards) XS650 engine. The earlier bikes used a "256-" series engine which was different in some small but very important details. There is also a "533-" series engine which I think was only sold in Europe.

    Other parts on our bikes - such as standard items like nuts and bolts (and yes, washers) were simply given part numbers of up to 12 digits because these very same parts were used on many different motorcycle models (and some are still used today in fact).

    Cheers,

    Pete

    I use stainless steel heavy pattern washers, better than the originals. I also used some cone washers from the local plumbing store to replace the rubber bushings, so far so good. remove pegs from brackets weld grind, paint, contact area so pegs sit straight.
    What have you done to your XS today?

    Hey gggGary i have been researching this RV 'plumbing' set up as the Mikes's one are rubbish, but for the life of me i cant find the cones anywhere down here. Part of my cross eyed interwebing the last few days is tracking some down with out getting stung $$ for international shiping. They do look good tho.
    Cheers
