Marine engine bearing set designed to restore bottom-end reliability for Yanmar 4LH series, Ellas-Wohnwelt Crankshaft and Connecting Rod Bearing Set. Replacing worn bearings can cut vibration and reduce the risk of sudden failure, reassuring owners and technicians. Is the set the practical choice for a full crank-and-rod service?
⚡ At a Glance
- • Durability: Includes crankshaft bearing, connecting rod bearing and Trust Bearing for bottom-end support
- • Best for: Owners and technicians performing maintenance or overhaul on Yanmar 4LH series engines
- • Not ideal for: Engines outside the specified Yanmar 4LH and 4LH-STE family
Set comprises crankshaft, connecting rod and Trust Bearing listed for Yanmar Marine 4LH and 4LH-STE applications. Components supply essential support for rotational and axial loads in the engine bottom-end.
Smoother crank rotation – with Crankshaft Bearing
Crankshaft bearing fits around the crank journals to provide a low-friction surface and maintain radial alignment under load. The bearing material and clearances allow oil film formation to separate metal surfaces during rotation.
Reduced friction leads to quieter running and less wear on journal surfaces, making it easier to return an engine to reliable operation after an overhaul.
Stable con rod support – with Connecting Rod Bearing
Connecting rod bearings sit between the rod and crank pin, sharing combustion and inertial loads across a replaceable surface. Properly sized bearings maintain clearance and oil film to prevent metal-to-metal contact.
Consistent rod bearing condition preserves engine compression and minimises knocking, which helps maintain power and longevity in daily use or under load.
Axial load control – with Trust Bearing
Trust Bearing manages axial forces on the crankshaft, keeping endplay within acceptable limits and preventing unwanted shaft movement. Correct axial support reduces wear to seals and adjacent components.
Effective axial support reduces seal wear and the chance of shaft misalignment, contributing to smoother shaft operation during sea trials and extended service intervals.
