Description
High-Performance Crankshaft Thrust Bearing for Cummins Engines
The Cummins 3691445 crankshaft thrust bearing is a critical component designed to control the axial (end-to-end) movement of the crankshaft within the engine block. Engineered to withstand extreme mechanical loads and high thermal stress, this thrust bearing ensures precise crankshaft alignment, reducing friction and preventing catastrophic engine wear. This part is also available under the numbers: 171977, A3691445, 369144500.
Engineered for Heavy-Duty Reliability
Manufactured from premium-grade materials, this thrust bearing offers exceptional wear resistance and load-carrying capacity. It is specifically designed for heavy-duty applications, including Cummins ISX, ISX15, QSX, and X15 EPA17 diesel engines. Proper installation of this bearing is essential during engine overhauls to maintain correct clearance and protect your engine’s bottom end from premature failure.
Key Features and Benefits
