Swing Device for Hitachi ZX470-5G Excavator | YB60000926

Product Overview

The swing device (also known as swing mechanism or swing assembly) is a critical genuine component that enables the upper structure of your Hitachi ZX470-5G excavator to rotate smoothly and precisely. This integrated assembly combines the swing motor, swing reduction gearbox, and parking brake into a single unit, delivering the torque and control needed for accurate positioning in mining, quarry, and heavy construction applications.

This is a genuine Hitachi original equipment part (Part No. YB60000926), manufactured to exacting OEM specifications for perfect fit, reliable performance, and long service life in the most demanding conditions.

Compatible Hitachi Models

Important: Please verify your machine's serial number range with our parts department to ensure correct compatibility, as swing device configurations may vary by production date and regional specifications.

Function & Operation

The swing device performs three critical functions:

1. Swing Motion: Converts hydraulic pressure from the main pump into rotational force (torque) to swing the upper structure

2. Speed Reduction: Planetary gears reduce speed while multiplying torque for smooth, powerful swing performance

3. Braking: Spring-applied multi-disc brake holds the upper structure securely when not swinging, and during parking

Common Failure Signs

• Insufficient swing torque or slow swing speed
• Excessive swing drift when stopping
• Unusual noise during swing operation (grinding, whining)
• External hydraulic leaks from motor or gearbox
• Parking brake failure - machine swings on slopes when parked
• Metal particles in swing gear oil
