ZF 4699.025.026 GP25 | OEM Genuine Part

Overview

The ZF 4699.025.026 GP25 is a precision-engineered OEM genuine part designed for heavy-duty construction machinery transmissions. This component functions as a critical gear or pump drive element within the ZF transmission assembly, ensuring efficient power transfer and hydraulic system operation. The SKU 4699.025.026 is specifically engineered to meet ZF’s rigorous standards for durability and performance in demanding off-highway applications. It sits within the transmission’s intermediate housing section, working in conjunction with the 4699101071 HOUSING and the 4699301145 HOUSING to maintain proper alignment and sealing of internal rotating assemblies.

Symptoms of Failure

When the ZF 4699.025.026 GP25 begins to wear, operators may notice specific performance issues. 1. Erratic gear engagement or slipping occurs when the part loses dimensional tolerance, causing inconsistent power delivery. 2. Hydraulic pressure fluctuations are common, as this component directly influences pump output. 3. Metallic debris in transmission fluid indicates surface degradation of the GP25. 4. Unusual whining or grinding noises from the transmission housing signal advanced wear, often requiring immediate replacement to avoid damage to the 4699309085 HOUSING COVER.

Technical Specifications

Compatibility

This OEM genuine part is compatible with ZF WG180, WG200, and WG210 series transmissions commonly used in construction machinery such as wheel loaders, telehandlers, and graders. It also fits select ZF Ergopower and Ecolife models with similar hydraulic pump drive configurations. Always verify the 0636101411 CAP SCREW torque specifications during installation to ensure proper clamping force against the mating housings.
