Component Work to be carried out
Intervals & Lifetime
[operating hours]
System oil Laboratory analysis 3000
Main fuel and lubricating oil filters
Check filter elements - in particular for white metal particles (clean or
replace filter as necessary). Follow manufacturer’s instructions
3000
Cooling water
Calculate quality, concentration of inhibitor and pH value (follow
instructions of inhibitor manufacturer)
weekly
Bedplate (Group 11xx) Check pre-tension of foundation bolts, first check after 1500 Op. h. 12000
Check condition of rubber gasket in the vertical oil drain to sump tank (see
SPC 9722), first time at the earliest opportunity after ship delivery. 30000 (replacement
recommended)
Estimated lifetime: Bedplate foundation bolts engine lifetime
Crankcase
Visual examination, 100 Op. h. after overhaul works: search for white
metal particles from bearings and for abnormalities in general.
1500 - 3000
Main bearing (Group 12xx)
Bearing shell inspection is only necessary if bearing clearance, crankshaft
deflection, wire check, oil analysis or crankcase inspection indicates
excessive wear or damage
at indications of excessive
wear or damage
Bearing edge check by wire 6000
Check bearing clearance see 0330-1 6000
Estimated lifetime: Main bearing shell
9000 (replacement if
required)
Thrust bearing (Group 12xx) Check axial and vertical clearances 6000 - 8000
Check bottom drain for free passage 6000 - 8000
Thrust bearing pads inspection is only necessary if bearing clearance, oil
analysis or crankcase inspection indicates excessive wear or damage at indications of excessive
wear or damage
Estimated lifetime: Thrust bearing
engine lifetime
(replacement if required)
Engine stays (Group 97xx)
Friction type: Check pre-tension of screws and remove corrosion marks
from friction elements, first time after sea trial
6000 - 8000
Hydraulic type: Check oil pressure at the gauge monthly
Tie rod (Group 19xx)
Check pre-tension, if necessary re-tension, first time after one year of ship
delivery
24000 - 30000
Estimated lifetime: Tie rod engine lifetime
Cylinder liner (Group 21xx) Measure liner wear (in installed condition) at every piston removal
Remove cylinder liner as necessary
Replace O-rings at every liner removal
Replace (soft iron) joint ring between cylinder liner and cylinder cover at every piston removal
Replace O-rings of water guide jacket and transition tubes at every liner removal
Check condition of antipolishing ring at every piston removal
Grind off wear ridge in bore at every piston removal
Refinish lubricating grooves as necessary
Clean scavenge ports and refinish their edges as necessary
Estimated lifetime: Cylinder liner Up to 90000
Lubricating quill (pulse lubrication,
group 21xx)
Check function and tightness at every piston removal
Check function of non-return valves at every piston removal
Gas admission valve (GAV, group
21xx)
Perform pressure check of gas manifolds for each engine side individually.
Tightness of the GAVs, the vent valve and the shut-off valve can be
confirmed by this check
12000
Overhaul/replace compression spring including valve seat lapping 30000-40000 (or 5 years)
Visual check of compensator gas inlet pipe 6000
Estimated lifetime: Rail valve 30000-40000 (or 5 years)
Estimated lifetime: Housing and servo drive engine lifetime
Piston rod gland (Group 23xx) Clean rings, establish wear at every piston removal
