Connecting Rod Bushing 38mm

The Connecting Rod Bushing 38mm ID (OEM # 4766404) is a critical component engineered for precision and durability in engine assemblies. Crafted from high-grade materials such as bronze alloy or steel-backed sintered metal, this bushing ensures optimal load distribution and articulation between the connecting rod and the crankshaft or piston pin. Its 38mm inner diameter is machined to exacting tolerances, guaranteeing a seamless fit for engines requiring OEM part # 4766404. Designed to withstand high cyclic stresses and temperature fluctuations, it plays a vital role in maintaining engine integrity, reducing metal-to-metal contact, and prolonging the lifespan of internal moving parts.

This bushing excels in minimizing friction and wear, thanks to its advanced surface treatments and anti-galling properties. Its robust construction ensures stable performance under extreme pressures, making it ideal for high-RPM applications in both automotive and industrial engines. The precision bore and interference-fit design prevent rotational slippage, while its thermal stability maintains dimensional accuracy even during prolonged operation. Whether used in passenger vehicles, heavy machinery, or performance engines, this component enhances fuel efficiency, reduces vibration, and supports smooth power transfer across the drivetrain.

OEM-certified and rigorously tested to meet factory specifications, the 38mm connecting rod bushing (part # 4766404) is a direct replacement for original equipment, ensuring compatibility with specific engine models from manufacturers that utilize this exact part number. Its design accounts for critical factors such as lubrication retention, alignment precision, and fatigue resistance, making it a reliable choice for rebuilds or repairs. Always verify compatibility using your engine’s service manual, VIN, or OEM database, as applications may vary across brands like Cummins, Caterpillar, or automotive OEMs. This bushing is a trusted solution for maintaining engine performance, reducing downtime, and avoiding premature component failure.
