ME997367 Mitsubishi BEARING SET,CONNROD, Price: 238.97$, Weight: 0.68kg

High-Precision Connecting Rod Bearing Set ?

This conrod big-end bearing kit is built for tight clearances and smooth running in popular Mitsubishi engines. It supports the rod on the crank journal, keeping the crankshaft centered and friction low during every power stroke. Designed to OE spec for rebuilds and performance refreshes, it restores quiet operation and stable oil pressure.

Why this part is needed ?️

These shells hold a precise oil film between the rod and crank. That film carries the load, prevents metal-to-metal contact, and controls heat. Fresh bearings protect journals, stop knock, and extend engine life.

How it works ?

Two half-shells seat in the rod and cap. With proper torque and oil, they form a hydrodynamic wedge as the crank turns. A tri-metal or Al-Sn layer conforms to tiny defects, while the backing keeps shape under high load.

What happens if damaged ⚠️

Worn bearings cause low oil pressure, dull knocking, hot spots, and metal flakes in oil. Severe wear can spin a shell, score the crank, or seize the engine—leading to costly machining or full replacement.

Signs and service tips ✅

Listen for rod knock on cold start, check copper showing on shells, and monitor pressure drops. Always replace as a full set, measure clearance with Plastigauge, use assembly lube, verify journal size, and torque to spec. Cleanliness is critical.
