Model: 4M10G110
Part Number: 1005174217
Brands: Baudouin
Engine Model: 4M10G110
Engine Type: Marine and industrial diesel
Scope of application: marine propulsion, marine auxiliary, generator sets
Rings seal combustion gas, conduct heat from the piston into the liner and scrape oil back to the sump. Set 1005174217 is specific to the Baudouin 4M10G110 rating, which differs from the G70 and G88 in piston and fuelling.
Worn rings do not stop a marine engine; they make it weak and smoky. Oil consumption rises, crankcase pressure builds and the engine stops reaching rated rpm, which on a boat is immediately noticeable as lost speed.
Although the 4M10G range shares many parts, the piston rings are matched to the piston groove geometry and the compression ratio of each rating. Fitting a G70 or G88 ring set to a G110 produces uneven tension, wrong end gaps and oil consumption that no adjustment can fix.
A tight gap breaks the ring when it heats, and an oversized gap allows blow-by that no tuning can remove.
Ring gaps must be measured in the liner the ring will actually run in, with the ring pushed square to a depth near the bottom of ring travel. Measuring in a different bore, or with the ring tilted, gives a reading that is wrong by enough to cause a failure.
New rings cannot fix a worn piston. Measure groove width with the old ring and a feeler gauge; an opened groove lets the ring flutter and break. Carbon packed into the groove corner also prevents seating, so clean properly rather than scraping the surface.
New rings need cylinder pressure to seat. Run at varying load, increasing gradually over the first hours, and change oil early. Holding full load immediately glazes the bores and leaves rings skating on a polished surface.
Marine fuel varies widely, and poor fuel accelerates ring and liner wear. Keep fuel filters changed and injectors serviced at the recommended hours. A leaking injector washes the bore and dilutes the oil, and the wear that follows is far more expensive than the service would have been.
Clean air and correct oil keep rings alive. Keep the air filter and engine room intake clean, use the specified oil grade and change it at the hours-based interval. Fix overheating promptly, because heat softens ring tension.
The oil used for break-in affects how quickly rings seat. A high-detergent oil can slow bedding-in because it keeps the bore too clean for the rings to mate. Many marine workshops run a short break-in period on the same oil grade but change it early, at twenty to fifty hours, to remove the metal produced while rings and bores wear together.
After break-in, use the specified grade for continuous duty. Marine engines often run at high load for hours, so the oil must resist oxidation and maintain viscosity at temperature. Topping up with whatever is on board is a false economy, because a mixed oil can foam and lose film strength exactly when the load is highest.
Check oil consumption against the log after the first hundred hours. A steady figure means the rings have seated; a rising figure means a gap or bore finish problem that should be investigated before it becomes bore damage.
Rings are supplied in protective sleeves because a bare ring can rust in a humid engine room within days. Keep them wrapped until the pistons are ready, and never mix rings from different sets even if the sizes look identical. A set that has been dropped should be inspected for distortion before use.
No. The G110 has its own piston and ring specification.
One set covers one piston.
Only if the measured gap requires adjustment.
Glazed bores, wrong gaps or rings fitted upside down.
Browse the Baudouin piston and components category, and pair the rings with the 4M10G110 piston 1005174216 or the 4M10G cylinder liner 1000156635.
Baudouin 4M10G110 Piston Ring (1005174217). Compression sealing and oil control both depend on this set. The top ring takes the highest temperature, the second supports sealing, and the oil ring returns oil to the sump.
Measure the old ring thickness and radial depth against the new set. A set that fits the groove loosely will flutter and break rather than seal.
Numbers beginning 1005 appear on WP8 and WP9 assemblies. Because the series was introduced to simplify supersessions, several older numbers map onto it. On this engine, confirm the 4M10G110 application against the engine plate before ordering.
Measure end gaps in the bore the ring will actually run in, with the ring squared by the piston crown. Measuring at the top of the bore or in a different liner gives a false reading.
Ordering note. Inspection reports can be provided for castings and crankshafts on request, covering the measurements taken before packing.
