Model: 4M10G88
Part Number: 1004882176
Brands: Baudouin
Engine Model: 4M10G88
Engine Type: Marine and industrial diesel
Scope of application: marine propulsion, marine auxiliary, generator sets
The 4M10G88 sits between the G70 and G110 in the Baudouin range. Part 1004882176 is the cylinder head for this rating, closing the combustion chamber and carrying the valve train, injectors and coolant passages.
The G88 is a common choice for auxiliary and light propulsion duty, where the engine runs at moderate load for long periods. That duty profile is gentle on the crank but steady on the head, so coolant condition and injector sealing decide how long the casting lasts.
Heads differ between 4M10G ratings in injector bore depth and port detail. Fitting a G70 or G110 head to a G88 changes combustion and produces hard starting, smoke and coolant leaks. Always confirm the casting number against the engine plate.
When the head comes off, look at the valve seats before cleaning them. A seat that is pitted on one side suggests a bent valve or a worn guide, not just normal wear. Re-cutting the seat without addressing the guide produces a head that seals briefly and then leaks again.
Match the engine plate, the old casting number and the injector type. Photographs of the old head and the nameplate let our team confirm the variant before shipping.
Light seat wear can be re-cut and a mildly warped deck machined once. Cracks between seats, at the injector bore or across the deck are not repairable in a way that lasts.
Check raw water flow and heat exchanger condition before blaming the head for overheating. On a boat, a fouled exchanger is far more common than a cracked head.
Head bolts are torque-to-yield and must be replaced every time. Reusing them reduces clamping force and produces a leak at high load that looks like a gasket failure.
Heads are skid-mounted with the deck covered, then banded. Stock heads normally leave the warehouse within three to five working days.
A pressure test fills the water jacket with air or water at above operating pressure and looks for loss. It finds porosity, cracks through the jacket and cracks from the jacket into a port. It does not find a deck that is warped but still sealed, which is why flatness is measured separately with a straight edge.
The two tests answer different questions and both are needed. A head can pass the pressure test and still fail in service because the deck is out of flat by enough to lift the gasket under load.
Before fitting a head, the deck must be bare metal. Old gasket material, carbon and sealant residue all keep the new gasket from seating. Use a scraper and a suitable solvent rather than a rotary abrasive, which can remove metal and change the flatness you just measured.
If the head is being replaced because of valve damage, the valves, springs and retainers should be renewed as a set. Reusing springs that have lost tension with new valves produces a valve train that floats at high speed, and on a marine engine that shows as a misfire at full load rather than at idle.
Ask us for the valve kit that matches the G88 casting when ordering, so that head and valve train arrive together and the workshop is not waiting on a second shipment.
No. Each 4M10G rating uses its own casting.
Yes, unless a bare head is requested.
No. They must be replaced every time.
Pressure test and combustion gas test.
Browse the Baudouin cylinder head category, and pair the head with the 4M10G88 overhaul kit 1004934489 or the 4M10G88 piston 1004934487.
Baudouin 4M10G88 Cylinder Head (1004882176). 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.
Photograph the deck, the casting number and the old gasket. Those three images usually identify the revision before anything ships, and they are far cheaper than a returned head.
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 4M10G88 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. Mixed pallets are accepted, so a single order can carry the block, the gasket set and the small seals together instead of arriving in three shipments.
