Model: 4M10G70
Part Number: 1000156637
Brands: Baudouin
Engine Model: 4M10G70
Engine Type: Marine and industrial diesel
Scope of application: marine propulsion, marine auxiliary, generator sets
The 4M10G70 is the lowest-rated engine in the Baudouin 4M10G family and is widely used for auxiliary duty, driving generators on working boats and in small industrial installations. Part 1000156637 groups the parts that wear together for a complete rebuild: pistons, rings, liners and the gasket set.
Although the G70 shares many parts with the G88 and G110, the pistons and rings are matched to its rating. Using a higher-rated kit produces the wrong compression ratio and changes combustion, which shows up as smoke, poor economy and higher exhaust temperature.
Confirm the engine serial number when ordering. Engines rebuilt before may carry a later head or a different piston batch, and the kit should match what is actually fitted.
On a genset, frequency droop under load is a useful indicator: an engine that has lost compression cannot hold its rated output, and the governor opens the rack further, raising exhaust temperature.
Three details decide the fit: engine model, compression ratio and head casting. Send photographs of the engine plate and the old piston crown and our team will confirm the variant before shipping.
Clean the heat exchanger and check the raw water impeller while the engine is apart. On an auxiliary engine that runs at steady load, a partially blocked exchanger is often why the engine was running hot before the rebuild. Check the injectors too: a leaking injector washes the bore and causes the wear that prompted the overhaul.
Run the rebuilt engine at varying load rather than holding a fixed generator setting. Break-in is usually done over the first twenty to fifty hours with load gradually increased and oil changed early. Holding rated load immediately glazes the bores.
Log 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 more useful than a generic service interval. The same log supports warranty discussions.
Kits are heavy but compact, with pistons and liners packed in foam-lined boxes and the gasket set flat to keep the head gasket uncreased. Tell us about consolidation so we can plan the load.
An engine that has worn one liner has usually worn all of them similarly. Mixing one new liner with the rest produces uneven compression, which on a genset shows as rough running and unstable frequency.
Individual parts look cheaper when only one cylinder needs attention, but the comparison is misleading. An engine that has worn one liner has usually worn all of them to a similar degree, and the labour to strip and rebuild is the dominant cost, not the parts.
Doing the job once with a matched kit is almost always cheaper than doing it twice with mixed parts. The kit also removes the risk of a mismatch between liner finish and ring type, which is the most common cause of oil consumption immediately after a rebuild.
Engines rebuilt before may already carry a later head or a different piston batch. Give us the engine serial number and a photo of the old piston crown and we will confirm the kit before it ships, rather than after it arrives at the yard.
No. Each rating has its own piston specification.
The standard kit covers pistons, rings, liners and gaskets. Bearings are separate.
Yes, the gasket set includes the head gasket.
Usually three to five working days for an experienced workshop.

Baudouin 4M10G70 Piston (1000156637). Heat and pressure both arrive at this component first. The ring grooves control oil and compression, and the bowl decides how efficiently the fuel burns.
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 1000 come from the newer numeric series used for assemblies and later-production parts. This series replaced several earlier numbers, so a cross-reference check is worthwhile. On this engine, confirm the 4M10G70 application against the engine plate before ordering.
Clean the ring grooves to bare metal before fitting new rings. Carbon at the bottom of a groove holds the ring proud and produces the same blow-by as a worn bore.
Ordering note. Payment terms and shipping method are confirmed in writing before dispatch, including the port of loading and the estimated transit time.
