One New Aftermarket Replacement Shaft-Pinion for Caterpillar (Cat) 345B Excavators
This pinion shaft is a key component of the swing drive group on Caterpillar 345 Series excavators. The swing drive pinion shaft transmits rotational force within the swing drive planetary assembly, enabling the upper structure of the excavator to rotate horizontally during operation. Replacing a worn or damaged shaft-pinion restores proper swing drive function and helps prevent further drivetrain damage.
