Frage;
Ich habe einige Zilinder die verrostet sind aber weiter noch gut.
Wieviel bertägt die toleranz zwischen Kolben und Zilinder?
Zb. wenn ein Kolben 73,00mm als übermass hatt, wie gross soll
der durchschnitt von den Zilinder dann geschliffen werden?
Ist die Toleranz für alle Kolben-übermassen gleich?
Bitte um expertise, kann das nml. nur einmal machen!
Gruss,
Martin

Hi Martin,
Sorry für schreiben in english.
Its normally the manufacturer of the piston who tells the tolerance between piston and cylinder, depending on the materials and manufacturing methods used.
Those tolerances stated in the DKW wartime workshops manuals are for the original DKW pistons and they are not valid if you use a modern repro piston.
Normally the cylinder is grinded to exact measures, for example 72.50mm, 73.00mm, 73,50mm and the manufacturer of the piston has took care of the tolerance when manufactured the pistons.
Normally the tolerance is stamped on the piston dome, for example 72.85mm, when cylinder then is grinded to 73.00mm, the tolerance is 0.15mm.
