ZF 4699.004.062 GK25 | OEM Genuine Part

Overview

The ZF 4699.004.062 GK25 is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This part functions as a critical interface within the gear train assembly, ensuring smooth power transfer and load distribution under extreme operating conditions. Specifically, the SKU 4699.004.062 serves as a guide or support element that maintains proper alignment of rotating shafts inside the transmission housing. When installed correctly, it reduces vibration and wear on adjacent components, directly contributing to the longevity of the entire driveline system. This part is commonly found in ZF’s modular transmission families used in wheel loaders, graders, and dump trucks.

Symptoms of Failure

• Transmission oil leaks around the housing interface: When the 4699.004.062 wears or cracks, hydraulic fluid may seep past seals, leaving visible puddles under the vehicle. This is a common long-tail search query for “ZF transmission oil leak repair.”
• Gear slipping under load: A degraded GK25 component can cause misalignment, leading to intermittent gear engagement. Operators often search for “transmission slipping when accelerating” as a symptom.
• Unusual whining or grinding noises: Worn surfaces on this part create metal-on-metal contact, producing high-pitched sounds during gear changes. This aligns with searches for “ZF transmission whining noise fix.”
• Increased vibration in the driveline: Loss of structural integrity in the 4699.004.062 allows excessive play, causing noticeable shaking through the chassis, especially at low speeds.

Technical Specifications

Compatibility

This part is engineered for use in ZF transmission models that share the GK25 housing architecture. Based on its design and application in construction machinery, the 4699.004.062 is compatible with the following ZF transmissions: WG180, WG200, WG211, and WG250. These models are widely deployed in heavy equipment such as loaders, dozers, and excavators. Always verify your transmission serial number before ordering.

During installation, the 4699.004.062 GK25 works in conjunction with several adjacent components. The 4699101098 HOUSING provides the primary structural enclosure, while the 4699301184 HOUSING serves as a secondary support shell. The 4699301015 HOUSING COVER seals the assembly against contaminants, and the 4699301085 COVER protects the internal mechanism from debris ingress. Proper torque sequencing of these parts is essential to avoid premature failure.
