Part Number: 1004708401
Brands: Baudouin

Scope of application: marine propulsion, marine auxiliary, generator sets, industrial power units
Every dimension in an engine is referenced to the block. It holds the crankshaft in its main saddles, supports the liners, provides the deck for the head and contains the coolant and oil galleries. Part 1004708401 is the cylinder block shared by the Baudouin 4M10G70, 4M10G88 and 4M10G110 engines, used in marine propulsion, auxiliary and industrial generator applications.
Because the block sets the geometry, it also sets the quality ceiling of a rebuild. A block with a warped deck or misaligned main bores destroys new bearings and gaskets regardless of how carefully everything else is assembled.
The three 4M10G ratings share this casting, which makes spare planning straightforward for operators running mixed fleets. Confirm the engine plate and the old block number before ordering: early and late production batches can differ in engine mount pads and in the front cover pattern.
Blocks are stripped, cleaned and measured before being offered. The checks are dimensional and pressure based, and the measurements can be supplied with the shipment.
Blocks ship cleaned with machined faces oiled and protected. Liners, cam bearings and gallery plugs can be fitted before crating on request.
A deck machined more than once may fall below minimum height, and a crack through a main saddle cannot be welded reliably because welding distorts bore alignment.
A pressure test plus a line bore check settles the question in most cases.
Match the casting number, front cover pattern and engine mount holes. Send photos of the old block from three angles with the engine plate and we will confirm the casting before loading.
Marine engines are cooled by raw water through a heat exchanger, and the block sees more corrosive conditions than a road engine. Check the water jacket for corrosion around the liner seats and the core plugs, and replace core plugs that show rust through. A block that has been run with poor coolant chemistry is often beyond saving even when the bores look acceptable.
The most common mistakes are fitting liners into a bore that was not cleaned properly, skipping the deck flatness check and reusing gallery plugs with old sealant. Each produces a failure soon after the engine returns to service.
Blocks are bolted to a timber base, banded and marked with lifting points, with the deck shielded. Freight is charged on volume as well as weight, so tell us whether the block travels with other parts.
Coolant quality prevents liner pitting, oil quality prevents bearing wear and healthy engine mounts prevent cracking. Replace a failed damper promptly and keep the heat exchanger clean so coolant temperature stays in range.
Marine blocks often carry more corrosion than road blocks because of the raw water circuit and the humid engine room. Before assembly, inspect the core plugs and the water jacket for rust breakthrough, and replace every core plug that shows staining. A plug that fails at sea is far more serious than one that fails on land.
Clean the oil galleries thoroughly and check the mating face of the heat exchanger and oil cooler for pitting. Refit gallery plugs with the correct sealant and confirm that every one is present before the crank goes in, because a missing plug means no oil pressure at first start.
It is supplied bare by default. Liners, cam bearings and gallery plugs can be fitted on request.

Baudouin Cylinder Block (1004708401). Every clearance in the engine is measured from this casting. That is why a replacement block is checked for deck flatness and main bore alignment before it is packed, and again when it arrives on site.
Ask for the casting number from the old block and compare it with the new one. Blocks from different revisions accept the same crankshaft and still refuse the brackets and front cover you already own.
Numbers beginning 1004 are numeric-series numbers used on later WP7 and WP8 production, where mounting detail changed without a change of nominal type.
Clean every oil gallery with brushes and confirm flow before assembly. Swarf left in a gallery destroys new bearings within minutes of the first start.
Ordering note. Inspection reports can be provided for castings and crankshafts on request, covering the measurements taken before packing.
