Model: 4M10G110
Part Number: 1005045623
Brands: Baudouin
Engine Model: 4M10G110
Engine Type: Marine and industrial diesel
Scope of application: marine propulsion, marine auxiliary, generator sets
The 4M10G110 is the most powerful rating in the Baudouin 4M10G range, which means the cylinder head sees the highest combustion pressure and heat load of the family. Part 1005045623 is the head specific to this rating, carrying the valve train, injectors and coolant passages.
Because the G110 runs at the highest fuelling, any weakness in the head shows up sooner. A deck that is slightly out of flat, or an injector seat that no longer seals, produces symptoms at full load long before it would on a G70.
The 4M10G range shares many castings, but heads differ between ratings in injector bore depth and port detail. Fitting a G70 or G88 head to a G110 changes combustion characteristics and typically produces hard starting, smoke and coolant leaks at the rear of the head.
Heads ship with valves and springs unless a bare head is requested, oiled and packed in a foam-lined carton.
A cooling system pressure test and a combustion gas test confirm the diagnosis before the engine is stripped.
An overhaul is the moment to have injectors checked. A leaking injector both dilutes the oil and washes the bore, and on a marine engine the damage is often blamed on rings or liners. Check the injector seat for carbon and pitting while the head is on the bench.
Match the engine plate, the old casting number and the injector type. Send photographs of the old head and the engine nameplate and our team will confirm the variant before the consignment ships.
Minor valve seat wear can be re-cut and a lightly warped deck machined once if enough material remains. Cracks between seats, at the injector bore or across the deck are not economically repairable.
Marine engines are cooled through a heat exchanger, and a fouled exchanger raises coolant temperature without any pump fault. Before blaming the head for overheating, verify raw water flow and exchanger condition.
Keep coolant at the correct concentration, replace the pump impeller and thermostat on schedule and clean the exchanger at the recommended interval. Marine hours accumulate quickly, so a generous-sounding interval arrives within months.
Head bolts are torque-to-yield and must be replaced every time the head is removed. Reusing them reduces clamping force, which shows up as a gasket leak at high load and is frequently blamed on the gasket rather than the bolts.
Heads are skid-mounted with the deck covered and the valve train protected, then banded. Stock heads normally leave the warehouse within three to five working days.
Worn valve guides let oil pass down the stems into the cylinders, producing blue smoke at start-up and after idling that clears once the engine is working. That pattern is often mistaken for worn rings, and the rebuild proceeds in the wrong direction. Measuring guide clearance on the bench takes minutes and settles the question.
Guides are replaceable, and a head that is otherwise sound can be reconditioned by fitting new guides and re-cutting the seats. Do this while the head is off; leaving worn guides in place means the new gasket set is wasted on an engine that still smokes.
No. Each rating has its own head casting.
Yes, complete with valves and springs unless a bare head is requested.
No. They are torque-to-yield and must be replaced.
A pressure test and a combustion gas test confirm it.
Browse the Baudouin cylinder head category, and pair the head with the 4M10G110 overhaul kit 1005174218 or the 4M10G cylinder block 1004708401.
Baudouin 4M10G110 Cylinder Head (1005045623). The head carries combustion pressure, the valve train and the injectors, and it has to seal all three against a block that expands at a different rate. It is the most highly stressed casting in the engine.
Compare the old head gasket with the new one before the engine is stripped: fire ring position, coolant hole pattern and thickness. If any of the three differ, check the casting number against the engine plate.
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.
Fit new head bolts every time. They are torque-to-yield fasteners and reusing them reduces clamping load exactly where the gasket needs it most, under load at working temperature.
Ordering note. Every shipment leaves with a packing list matched to the invoice, which matters when a rebuild is waiting on one seal and the whole pallet has to be cleared through customs.
