Floating piston pins - Fitting of conrods
Posted: November 13th, 2006, 12:07 pm
I have some peugeot sport Mahle forged pistons that have fully floating pins. (They are designed for a 1294cc 205 Rallye)
I am not using these right now. However I have been offered a set of modfied connecting rods that have been modfied to fit forged pistons. The measurement of the small ends are claimed to be 20mm.
I measured the pins on my pistons (with a digital slide) and I measure 19.98, 19.97.
I have little knowledge of the tolerance in the fitting of floating pistons. Does this sound like a good fit for my pistons. Or am I better off getting someone to machine my standard conrods to fit (which are normally a smaller interference fit)?
Thanks
Christopher
