[diesel_mercedes] Piston Fitment

 

As it turns out , they way you fit German pistons is different from how Americans do it :

Americans measure the side clearance between the cylinder wall and the piston as the narrowest point , if within specification , it's good to go , call it a day .

Germans , however , measure every piston in the shop with a micrometer and write it on each piston or in a book then measure the bore and match them up ~ the similar result is much closer the German way and is why these engines (and those VW's 40 years ago) last so long .

Coupled with fabulous piston quality in both materiel and initial manufacture , often the Mercedes pistons are unworn after 1/2 million miles of service .
