    Series 2/2a piston

    Hi All.

    Hope someone out there would have the details im chasing.

    I require if possible a complete detail spec on the pistons that was used in the Series 2 2a petrol motors. I know it strange, but trying to help a friend out.

    The details are the exact measurement of the piston including ring grooves and gudgeon pin size.

    Thanks in advance.

    Robert

    There are original and after-market replacements where different manufacturers can have different spacings and particularly for the oil/scraper ring.

    Surely what you want is the height of the piston and the centre of the gudgeon pin.

    I can try to measure some over the weekend but not before Friday.

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.
