One New Aftermarket Replacement Planetary Carrier Assembly for Caterpillar (Cat) 330B Series Excavators
This aftermarket replacement planetary carrier assembly (Carrier AS) is a critical component of the final drive system on Caterpillar 330B-series track excavators. The planetary carrier supports the planet gears within the final drive gearbox, transmitting high-torque output from the hydraulic travel motor to the undercarriage drive sprocket. A worn or damaged carrier causes sluggish travel, uneven track speeds, and drivetrain noise -- replacing it restores full propulsion performance. This part is identified in the Caterpillar parts catalog as a Carrier Assembly (Carrier AS) within the final drive group.
