The 4M10G is the four-cylinder member of the Baudouin M10 marine engine family, used for propulsion and auxiliary duty on working boats and for industrial generator sets. Part 1004720472 is the camshaft shared by the 4M10G70, 4M10G88 and 4M10G110 ratings, carrying the intake and exhaust lobes plus the drive gear for the injection pump.
Valve timing on a marine engine matters as much as on a road engine, but the duty cycle is harder. These engines often run at constant load for hours, then idle while manoeuvring, then go straight back to load. That pattern puts steady thermal and mechanical stress on the valve train and makes lobe wear a real maintenance item rather than a rare failure.
Because the same camshaft serves all three 4M10G ratings, fleets running mixed engines can keep one spare. The ratings differ mainly in fuelling and boost, not in valve timing, which is why one profile covers them. Confirm the engine plate and the old camshaft number before ordering, since early and late production batches can differ in the pump drive gear.
Shafts are forged from alloy steel, heat treated, induction hardened on lobes and journals, then ground to the original profile. The checks that decide durability are done on every unit.
Shafts ship oiled and sleeved in a rigid tube, with bearings and thrust plate available pre-fitted on request.
On a marine engine the first sign is often a slight loss of rated speed or rising exhaust temperature at the same throttle setting, long before any noise appears. On land-based units the tapping at the valve cover is usually noticed first.
Measure lift before replacing parts. Adjusting clearance cannot recover a flattened lobe.
Match the part number, the engine rating and the pump type. A shaft from a different rating may fit but change valve timing and emissions. Check the number stamped on the existing shaft if the engine has been rebuilt before.
Marine engines run in a corrosive atmosphere and often with limited maintenance windows. Keep the breather clean so oil mist does not carry salt-laden air into the valve chamber, and change oil at the hours-based interval rather than a calendar interval. Check valve clearances at every major service, because a tight clearance burns a valve and hammers the lobe.
The camshaft is one link in a gear train. A worn crank gear or slack idler changes valve timing and hammers the lobes, so a rebuilt engine should have the whole train inspected. Measure backlash and look for a polished or stepped tooth pattern before fitting a new shaft.
Camshafts are long and slender and bend easily in transit. They ship in rigid tubes with journals protected, braced inside the carton so the tube cannot flex. If the shaft travels with heavy parts, tell us so we can place it where nothing rests on it.
Marine engines are usually maintained on running hours rather than distance, and the valve train is often the first thing neglected because it is hidden. A working boat that runs 2,000 hours a year reaches the equivalent of a truck's annual mileage in a few months, so valve clearances drift out of specification far faster than most operators expect.
Check clearances every 500 hours on continuous-duty installations and every 250 hours on engines that are started and stopped frequently. Recording the figures lets you see a lobe wearing before it becomes a failure, which is far cheaper than a mid-season strip-down.
Yes, the same profile covers 4M10G70, 4M10G88 and 4M10G110. Confirm the pump drive gear on early engines.
Yes. Used lifters match the old lobes and will scuff a new shaft.
Always verify pump timing after fitting a camshaft.
The shaft comes with its gear fitted. A bare shaft is available on request.
Browse the Baudouin camshaft category, and pair the shaft with the 4M10G crankshaft 1004743021 or the 4M10G cylinder head range.
Baudouin Camshaft (1004720472). The camshaft times the valves and, on most of these engines, drives the injection pump. Lobe profile and gear timing therefore affect both breathing and fuelling.
Photograph both ends of the old shaft before ordering, and note the gear tooth count where it is accessible. Fitment here is decided by the drive end, not by the bearing journals.
Numbers beginning 1004 are numeric-series numbers used on later WP7 and WP8 production, where mounting detail changed without a change of nominal type.
Fit new lifters, bearings and a thrust plate with the shaft. Used lifters carry the wear pattern of the old lobes and scuff a new camshaft within minutes of running.
Ordering note. Photographs of the actual unit can be sent before dispatch on request. That is the cheapest way to avoid a return when a casting revision is in doubt.
