Product Description
199-4538 199-4539 200-3372 Swing Drive & Motor Assembly for Caterpillar 330C 330D 336D High-Torque Swing Reducer
Product Overview

The swing motor assembly and planetary reducer are the power centers for the Caterpillar 330/336 series. These units are designed to handle the immense inertia of a loaded 30-ton excavator upper structure, ensuring precise positioning and rapid cycle times.

Our assemblies are precision-matched to specific configurations:

199-4538: Standard for 330D series Swing Drive groups.

199-4539: Common as the primary reduction gearbox for 330C/330D.

200-3372 / 200-3373: Specific to the 330D/336D Swing Motor groups.

Maintenance & Expert Advice
Product Selection Tip: To ensure a 100% match, please provide your excavator's Serial Number (S/N). The hydraulic flow configurations can vary based on the machine's region of origin or specific attachment requirements.

Lubrication: Always use Caterpillar-recommended hydraulic oils (such as CAT HYDO Advanced) to maintain the critical lubrication film between the internal pistons and the distributor plate.

Inspection Cycle: It is highly recommended to check gear oil levels and seal integrity every 500 operating hours. Any unusual grinding noise or sluggishness usually indicates the need for an internal gear mesh inspection.

Key Features & Benefits

  • High-Torque Planetary Drive: Features a multi-stage planetary gear system (sun gears and planet carriers) that delivers massive starting torque, allowing the machine to start and stop rotation smoothly even with a full bucket.

  • Zero-Drift Braking System: Integrated with high-precision valve groups and a spring-applied, hydraulic-release parking brake. This system prevents "Swing Drift" when working on inclines, ensuring operator safety and site precision.

  • Heavy-Duty Durability: Internal gears are induction-hardened to resist fatigue, while the external housing is cast from heavy-duty steel. Premium floating seals and roller bearings protect internal components from the abrasive dust found in mining and demolition sites.
