ZF 4699.025.167 GP25 | OEM Genuine Part

Overview

The ZF 4699.025.167 GP25 is a precision-engineered genuine OEM part designed for integration within heavy-duty ZF transmissions used in construction machinery. This component serves as a critical intermediary within the gear train assembly, ensuring consistent torque transfer and smooth power distribution under extreme load conditions. The SKU 4699.025.167 is specifically calibrated to maintain the exacting tolerances required for long service intervals in excavators, wheel loaders, and graders. When installed, it works in concert with the 4699101164 HOUSING and the 4699301250 HOUSING to form a sealed, lubricated chamber that protects internal gears from contamination and wear.

Symptoms of Failure

• Erratic gear engagement and delayed shifting: When the 4699.025.167 wears, operators often report a noticeable lag or hesitation when shifting between forward and reverse gears, particularly under load. This is a common long-tail search query for “ZF transmission hesitation under load.”
• Metallic grinding noise from the transmission housing: A distinct whining or grinding sound, especially during acceleration or deceleration, indicates that the GP25 component has lost its surface hardness or developed pitting. This symptom is frequently searched as “grinding noise ZF WG200 transmission.”
• Hydraulic fluid contamination with metallic particles: Internal degradation of this part releases fine metal shavings into the transmission oil. This is often detected during routine oil changes and is a key indicator of “ZF transmission metal shavings in oil.”
• Oil seepage around the housing cover interface: If the GP25 component shifts out of alignment, it can compromise the seal between the 4699309122 HOUSING COVER and the main casing, leading to visible oil leaks near the bell housing.

Technical Specifications

Compatibility

This genuine ZF 4699.025.167 GP25 component is engineered for direct fitment into the following ZF transmission models commonly found in construction machinery: WG180, WG200, and WG211 series. It is also compatible with certain variants of the ZF 4WG-200 and ZF 6WG-250 power shift transmissions. Always verify the transmission serial number before installation. For secure mounting, the 0636101411 CAP SCREW must be used in conjunction with the housing assembly to prevent vibration loosening.
