The Hyundai XKAH-00855 Gear Pump Assembly is an original equipment manufacturer (OEM) hydraulic component engineered for Hyundai Construction Equipment (HCE) mini excavators. This gear pump serves primarily as a pilot pump in the hydraulic system, facilitating smooth and efficient fluid circulation essential for operations such as boom, arm, and bucket movements.
Key Features and Specifications:
- Compatibility: Specifically designed for Hyundai 7-Series and 3-Series crawler excavators, including models R55-7, R55-7A, R55-3, R60-7, and similar variants (e.g., DX55-7 under Doosan branding due to affiliations). It may also cross-reference with updated part XKAH-00917 for enhanced applications.
- Construction: Built with durable casings, precision gears, seals, and plates to withstand high-pressure environments typical in excavation machinery. It aligns with AP2D28/AP2D25 series standards for flow rates around 2000 cc/min at 1500 rpm, ensuring optimal hydraulic efficiency.
- Performance Benefits: Provides reliable pilot pressure for main hydraulic pumps, reducing wear and improving overall machine responsiveness. Ideal for 7-8 ton class excavators in construction, landscaping, and utility work.
- Maintenance Notes: Regular inspection of related components like O-rings (e.g., XJDD-00859) and casings (e.g., XKAH-00858) is recommended. This part is backed by Hyundai’s quality standards for longevity and safety.
