Diagram ref no 10, 11 & 12.
Each bearing shell is produced with smooth, low-friction bearing surfaces and consistent wall thickness to maintain correct rod-to-crankshaft clearances when installed in the rod big end. The standard size designation indicates these bearings retain factory bore dimensions, ideal for engines where no crankshaft undersize machining has been performed.
Big end bearing shells provide the low-friction interface between the connecting rod and crankshaft journal. They help to support dynamic engine loads and maintain a stable lubricating oil film that protects both the rod and crankshaft from metal-to‐metal contact. With proper oil flow and clearance, these bearings help ensure reliable rotation and reduce wear under normal and high-load conditions.
Installed in pairs inside each connecting rod’s big end bore, these bearing shells support the rotating crankshaft by maintaining correct clearance and offering a durable, smooth surface for the journal to ride on. Their design promotes even oil distribution and stable hydrodynamic lubrication - essential for wear resistance, smooth engine operation, and long service life.
Big end bearings are central to engine bottom-end integrity. They endure high loads, RPMs, and constant motion. Over time or due to lubrication issues, bearings can wear, lose material, or show surface degradation - leading to increased clearances, knocking noises, reduced oil pressure, and accelerated wear of the crankshaft journal.
Replacing worn bearings with OE Match shells during a rebuild restores proper oil clearances and hydrodynamic lubrication, helping protect the crankshaft and rod journals from premature wear while supporting smooth, reliable engine operation.
When to replace:
• Engine is undergoing rebuild or overhaul
• Bearing wear, noise, or rod knock detected
• After lubrication or oil starvation incident
• During high-mile preventive maintenance
• When crankshaft journals are within standard size (no undersize needed)
