ZF 4699.019.002 GP19 | OEM Genuine Part

Overview

The ZF 4699.019.002 GP19 is an OEM genuine part engineered for precision fit within ZF’s heavy-duty transmission assemblies. This component functions as a critical interface element, managing hydraulic flow and mechanical alignment inside the gearbox housing. Specifically, the SKU 4699.019.002 sits adjacent to the 4699101152 HOUSING and works in concert with the 4699309059 HOUSING COVER to seal and stabilize the internal drivetrain. Designed for construction machinery applications, this part ensures consistent torque transfer and reduces vibration under extreme loads.

Symptoms of Failure

• Hydraulic fluid seepage around the transmission casing: Worn sealing surfaces on the GP19 allow oil to escape, often visible as drips near the housing joint.
• Intermittent gear engagement hesitation: A degraded 4699.019.002 disrupts pilot pressure, causing delayed shifting during heavy operation.
• Abnormal metallic rattling from the bell housing area: Loosened fitment leads to contact between the GP19 and adjacent 0636101411 CAP SCREW fasteners, generating noise.
• Reduced transmission oil pressure readings: Internal leakage past the GP19 lowers system pressure, triggering warning codes on loaders and excavators.

Technical Specifications

Compatibility

This GP19 component is designed for ZF’s WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, telehandlers, and graders. It also fits select variants of the 4WG-200 and 6WG-200 power shift units. The part interfaces directly with the 0631302212 CYLINDRICAL PIN for alignment and requires the 4699102187 INPUT shaft for complete assembly. Always verify housing compatibility using your transmission serial number before installation.
