    so this weekends job is hone, assemble rods and pistons, and install.

    just this minute putting the pistons and rods together and i notice this:

    as you can see, pin is all the way in, right up to the circlip.

    the other side:

    Not in far enough to put the other circlip in. Doh

    my first thought was to a recent post of tufftys with 2 different 20mm pins, different lengths.
    so im guessing mine are too long for my AGU pistons?? The seller probably found the same thing out

    ****.

    what can i do now?

    :wub:

    seems to me you can buy wrist pins in pretty much any size you need, i've found some tool steal items from probe industries.

    these i have are 2.4 inches/mouses pube under 61mm.
    Do the pins have to sit perfectly inbetween the circlips? i.e. no side to side movement whatsoever?

    maybe il just get these machined down?

    there is a little wiggle room on them, not hard to the circlip as std no

    They are 9.5:1 pistons. Ive clearly been given the wrong pins with these.
    There is definately no wiggle room bill. As you can see its butted right up to the circlip on t'other side.
    I dont suppose theres a set of pins lyong around your workshop bill??
    Tuffty, do you happen to know the length of that correct pin in your picture?

    Ahh yes i misinterpreted your answer.

    Pins i have here are 2.4inch/61mm.

    At a guess the correct size is prob 58-59mm judging by the room i need and tufftys picture.
