Group Component Work to be carried out Intervals
2303 − 1 Piston rod gland − Clean rings, establish wear at every piston removal
2708 − 1 Cylinder cover − Check combustion space for damage at every piston removal
2722 − 1 Injection valve − Check externally for tightness before starting engine
after a longer standstill
− Check spray pattern, opening pressure, tightness
condition of nozzle tip, readjust opening pressure

spindle and valve seat
(without dismantling of exhaust valve)
at every piston removal
2751 − 4 − Check condition and wear of valve spindle
(if necessary regrind seat by machining)
24 000 − 36 000 Op. h
− Check piston seal ring / air spring & rod seal ring /
guide bush
