ZF 4699.819.005 GP19 | OEM Genuine Part

Overview

The ZF 4699.819.005 GP19 is a genuine OEM gear pump assembly designed for integration within ZF heavy-duty powershift transmissions. This component, identified by SKU 4699.819.005, serves as the primary hydraulic pressure source, delivering lubrication and clutch actuation fluid throughout the transmission system. Positioned directly on the transmission housing, it draws oil from the sump and pressurizes it for distribution. For optimal assembly integrity, this unit is often paired with the 4699019004 GP19 pump element and the 4699101161 HOUSING to ensure proper sealing and flow dynamics.

Symptoms of Failure

• Hydraulic pressure loss during operation – A worn GP19 pump will fail to maintain adequate pressure, leading to sluggish clutch engagement and reduced machine performance.
• Erratic gear shifting or slipping – Insufficient lubrication from a failing pump causes intermittent gear slippage, particularly under load in construction machinery.
• External oil seepage around the pump mounting – Deteriorated seals or housing cracks allow transmission fluid to leak, often visible as drips near the pump interface with the 4699102187 INPUT shaft area.
• Whining or grinding noise from the transmission – Cavitation or bearing wear within the pump generates high-pitched sounds, indicating imminent failure of the 4699103125 OUTPUT drive components.

Technical Specifications

Compatibility

This genuine ZF part is engineered for use in the following transmission models commonly found in construction machinery such as wheel loaders, dozers, and graders:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310

Always verify your transmission serial number before ordering. The 4699.819.005 replaces earlier pump variants and requires compatible 4699101161 HOUSING and 4699102187 INPUT components for correct fitment.
