Model: 4M10G70
Part Number: 1004713403
Brands: Baudouin
Engine Model: 4M10G70
Engine Type: Marine and industrial diesel
Scope of application: marine propulsion, marine auxiliary, generator sets
On the Baudouin 4M10G70 the cylinder head closes the combustion chamber, carries the valve train and routes coolant around the injector and valve bridges. Part 1004713403 is the head for this rating, used in marine propulsion and auxiliary installations.
The head is where heat and pressure meet. Combustion pressure pushes down on the deck while the casting is heated unevenly, and the gasket must hold while the metal expands and contracts. A head that has warped or cracked passes coolant into the cylinder or compression into the water jacket.
Although the 4M10G range shares many parts, the cylinder heads differ between ratings in injector bore and port detail. Fitting a G88 or G110 head to a G70 changes combustion characteristics and often 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 on machined faces and packed in a foam-lined carton.
A cooling system pressure test and a combustion gas test confirm the diagnosis in minutes and save stripping a healthy head.
Match the engine plate, the old casting number and the injector type. On engines that have been rebuilt before, the head may be from a later production run. 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 can be machined once if enough material remains. Cracks between valve seats, at the injector bore or across the deck are not economically repairable. A repaired head that fails again usually takes the gasket with it.
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 that raw water flow is adequate and the exchanger is clean. On a working boat this simple check saves a great deal of unnecessary work.
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 service interval that sounds generous on paper arrives within months.
Heads are fixed to a timber skid with the deck covered and the valve train protected, then banded so nothing moves in transit. Stock heads normally leave the warehouse within three to five working days.
An overhaul is the right moment to have the injectors checked and, if needed, replaced. 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 when the injector was the cause.
Check the injector seat in the head for carbon build-up and pitting. A seat that no longer seals lets compression escape past the copper washer, which shows as a chuffing noise and a hard-to-diagnose misfire. Cleaning or re-cutting the seat while the head is on the bench is far easier than doing it later.
No. Each rating has its own head casting. Ask us for the matching part.
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 before stripping.
Browse the Baudouin cylinder head category, and pair the head with the 4M10G cylinder block 1004708401 or the 4M10G camshaft 1004720472.
Baudouin 4M10G70 Cylinder Head (1004713403). 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.
Confirm the injector bore depth matches the injectors in use. Shimming an injector to compensate for a different bore is a common shortcut that produces smoke and hard starting.
Numbers beginning 1004 are numeric-series numbers used on later WP7 and WP8 production, where mounting detail changed without a change of nominal type. On this engine, confirm the 4M10G70 application against the engine plate before ordering.
Have the head checked for flatness and, where necessary, pressure tested before assembly. A crack that does not leak cold will open once the engine reaches temperature.
Ordering note. Packing is export grade: each unit is wrapped, boxed and palletised for sea freight, with the part number marked on the outside so the receiving store can book it in without opening the carton.
