Man B&W 0.4-0.8% FROM NOMINAL DIAMETR DEPEND ON CYLINDER CONDITION.
IF YOU LINER DIAMTER 500MM MAXIMUM WEAR IS 500*0.4%=502MM, OR 500*0.8%=504MM
IMPORTANT IF PISTON WITH CROWN AND PISTON RINGS ARE NEW, PERFORMANCE STILL GOOD WITH WEAR 503MM, NOT NESESSARY TO REPLACE LINER, BUT OFFICE AND C/E DECIDE THIS.

Any one here knows that ,do me a fever. Thanks a lot
