PC40-8 2nd Stage Planetary Carrier Assembly Komatsu Mini Excavator Swing Reduction Gearbox Repair Part

The PC40-8 2nd Stage Planetary Carrier Assembly is a replacement component designed for swing reduction gearbox repair and maintenance on compatible Komatsu mini excavators.

The planetary carrier supports the planetary gears within the reduction mechanism. Correct component selection is important for maintaining compatibility with the original swing reducer assembly.

This product is intended for replacement and repair applications. It is not a complete swing reduction gearbox.

The product image describes the component as hardened steel. Please confirm the exact material grade, heat-treatment specifications and other technical details with the supplier before relying on them for equipment selection.

This component is listed for the Komatsu PC40-8 mini excavator. Actual compatibility should be verified against the machine serial number, swing reducer version and original part number.

Before ordering, compare the existing component's overall diameter, center bore, mounting holes, gear engagement and locating features. These checks help identify the appropriate replacement and reduce the risk of ordering an incompatible part.

During swing reduction gearbox maintenance, inspect the related planetary gears, bearings and mounting surfaces as appropriate. Worn or damaged components should be assessed according to the equipment manufacturer's service requirements.

Confirm that the required component is the second-stage planetary carrier rather than a first-stage carrier or a complete gearbox assembly.
