    ok so the piston number is only on the box and is,
    TS2100

    The rod number is
    625-5250.

    And it appears the bottom of the rod is locked in place too (bottom and top guided ??).

    The main issue is the roller bearings can move out of place too much due to the wider piston boss. So perhaps just the right kind of washer is what is need to keep them in place ?

    I had some of the big rods in a motor I tore down that had the wide base pistons with a skinny rod they had a thick washer on each side. I don't remember the thickness but I'd guess .080 to .100
    Measure the piston boss to boss, measure the rod width at top, subtract from the big number, divide by 2, add a little clearance.
    Now you need 12 of them. $ .02

    Hey Thanks Nice Pair, I'll get some hardened washers and put them in, just wanted to make sure that was acceptable to that.

    Cheers and Happy Xmas to all.

    You want to be careful, ck with somebody that knows the difference. (and can explain it to you) I believe those thick washers were a Mercury part
    What I did was a ways back and I don't remember all of it.

    I had some (as I remember) 5250 top guided rods (the rod end was wide) and I had a machine shop cut them down to the same thickness as the bottom guided rods and used bottom guided pistons. (I think that is the setup that uses those cute little washers to keep the needles from falling out.

    Have a great Christmas. NP
