can't find where but someone gave me the numbers for the 470HC piston (wossner code is 8552) and gave the height over the pin as 13.0mm but i have measured 4 pistons now, the first was 12.7 and the last three were 12.4mm.
so by my records, the 8602 (550) is 13.3mm, the 8551(650) is 12.7mm, the 8552 (470HC) is 12.4mm. so who ever gave me that "13.0mm" i think was having an odd one!
