Model: 4M10G88
Part Number: 1004934489
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 the G110 in the Baudouin 4M10G range. Many parts are shared across the range, but the pistons and rings are matched to the rating, which is why this kit is specific to the G88. Part 1004934489 groups the parts that wear together so a rebuild can be planned as one shipment rather than eight.
For a working boat, the logistics matter as much as the technical match. A shipyard window is short, and one missing gasket can keep a vessel alongside for a week.
Confirm the engine serial number when ordering. Engines rebuilt before may already carry a later head or a different piston batch, and the kit should match what is actually fitted.
On a marine engine the rated rpm check is quick and revealing: a propeller that used to reach 2,300 rpm and now stops at 2,200 is telling you the engine has lost power somewhere.
Three details decide the fit: engine model, compression ratio and head casting. A G70 or G110 kit will physically assemble but give the wrong compression ratio on a G88. Send photographs of the engine plate and the old piston crown and we will confirm the variant.
Clean the heat exchanger and replace the raw water impeller while the engine is apart. Scale in the exchanger is often why the engine was running hot before the rebuild, and leaving it means the new engine inherits the same problem.
Run at varying load rather than holding one setting. Break-in is usually done over the first twenty to fifty hours with load gradually increased and oil changed early. Holding full load immediately glazes the bores.
Kits are heavy but compact. Pistons and liners are packed in separate foam-lined boxes inside one carton, and the gasket set is packed flat to keep the head gasket uncreased. Tell us about consolidation so we can plan the load.
Individual parts can look cheaper when only one cylinder needs attention, but an engine that has worn one liner has usually worn all of them similarly. Mixing one new liner with the rest produces uneven compression, felt on a boat as vibration through the hull.
Marine fuel quality varies widely, and poor fuel accelerates ring and liner wear. Keep the fuel filters changed and the injectors serviced at the recommended hours. A leaking injector both dilutes the oil and washes the bore, and the rebuild that follows is twice as expensive as the injector service would have been.
Change oil at the hours-based interval, keep coolant chemistry correct and check valve clearances at every major service. Inspect the engine room ventilation as part of the routine, because a hot engine room raises intake air temperature and costs power.
Keep a rebuild log for every marine engine: hours at overhaul, parts fitted, clearances measured and oil analysis results. When the next overhaul comes, the records show what wore and how fast, which is far more useful than a generic service interval from a manual.
The same log supports warranty discussions and helps a new owner understand the vessel's history. For operators with several boats, consistent records make it possible to compare engines and spot one that is wearing abnormally.
No. Each rating has its own piston specification. Ask us for the matching kit.
The standard kit covers pistons, rings, liners and gaskets. Bearings are separate.
Yes, the gasket set includes the head gasket for the matching casting.
Usually three to five working days for an experienced marine workshop.

Baudouin 4M10G88 Piston (1004934489). This piston carries the combustion load and forms half of the combustion chamber. Its crown profile is matched to the rating, not just to the bore diameter.
Compare the old piston crown with the new one. Two pistons can share a diameter and differ in bowl shape, compression height or groove width, and a wrong bowl produces smoke with no other symptom.
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.
Check piston-to-bore clearance and ring end gaps in the actual bore. Measuring in a spare liner gives a false reading and is a common cause of oil use after a rebuild.
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.
