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
(life time of nozzle tip about 6000 Op. h)
3000 Op. h
2728−1 Starting air valve − Check piping before the valve during operation,
if piping is too hot, dismantle starting air valve
weekly
− Remove and dismantle one starting air valve at
random. From its condition determine time of
overhaul for remaining valves
6000−8000 Op. h
− Make sure that nut on solenoid is tight,
if necessary tighten nut.
monthly
− Solenoid valve, random functional check
overhaul
6000 Op. h
18 000 Op. h
2751−1
to
Exhaust valve − General inspection of valve housing, valve
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
24 000−36 000 Op. h
− Check condition and wear of valve seat
(if necessary regrind seat by machining)
24 000−36 000 Op. h
− Random check of valve drive, outside and
inside pistons, damper, thrust piece
18 000 Op. h
− Random check of sc. conn. to measuring cone 18 000 Op. h

3103−1 Crankshaft − Measure crank deflection
− Always in case of grounding of the ship as well as
before and after every docking
according to
classification society
3130−1 Torsional
vibration damper
− Take a silicon oil sample from viscous vibration
damper (based on results of 1
st
sample, interval
for taking further samples will be decided)
first time after 15 000 −
18 000 Op. h
3130−2 − Inspection interval and dismantling of
GEISLINGER damper
acc. to instructions of
damper manufacturer
3140−1 Axial damper − Dismantling and inspection 36 000−48 000 Op. h
