King Engine Bearings CR6699CA0.75 Connecting Rod Bearing Set +0.75mm Undersize for Cummins 6B Series

The King Engine Bearings CR6699CA0.75 is a complete connecting rod bearing set engineered for Cummins 6B Series diesel engines. This set is produced in a +0.75mm undersize dimension, designed specifically for use with crankshafts that have been reground to the corresponding undersize specification during engine rebuild or reconditioning.

King's CA (Copper-Aluminum tri-metal) bearing material is a premium alloy construction that delivers an optimal balance of strength, fatigue resistance, and conformability. The tri-metal design layers a copper-lead or copper-aluminum based overlay over a steel backing, providing excellent load-bearing capacity suited to the demands of heavy-duty diesel applications like the Cummins 6B Series.

Key Features:

• +0.75mm Undersize — engineered for engines with crankshafts reground to +0.75mm undersize during rebuild
• Tri-Metal CA Construction — copper-aluminum alloy material for superior strength and wear resistance in heavy-duty diesel engines
• OE-Replacement Grade — manufactured to meet or exceed original equipment specifications for the Cummins 6B Series
• High Fatigue Resistance — engineered for the high cylinder pressures and loads inherent to Cummins inline diesel engines
• Precision Tolerances — tight manufacturing tolerances ensure proper oil clearance and long service life
• Lead-Free Compliant — King's CA material line utilizes lead-free alloy compounds for environmental responsibility
