This OEM thrust bearing (part 6304704X) is a precision-engineered crankshaft axial thrust control component designed specifically for Shacman H3000 heavy-duty commercial trucks equipped with Cummins engines. The 6304704X thrust bearing controls the axial end-play of the crankshaft within the engine block, absorbing forward and rearward thrust forces generated by clutch actuation and gear reactions to maintain proper crankshaft positioning under all operating conditions.
Manufactured from premium high-grade multi-layer bearing materials with exact dimensional specifications, precision forming processes, and specialized surface coatings, this 6304704X thrust bearing withstands continuous high axial clamping loads, extreme oil film shear stresses, severe thermal cycling, and prolonged intensive service during demanding heavy-duty commercial vehicle applications.
Replacing a worn, scored, or excessively end-play thrust bearing with this genuine 6304704X component restores proper crankshaft axial positioning and prevents crankshaft walk damage. The OEM part number guarantees exact dimensional specifications and factory-engineered quality specifically validated for Shacman H3000 Cummins truck engines.
