ZF 4699.801.094 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.094 GK10 is a critical OEM genuine component engineered for the internal shift mechanism of heavy-duty ZF transmissions used in construction machinery. This part functions as the primary actuation hub within the valve body assembly, directing hydraulic pressure to engage specific gear sets. The SKU 4699.801.094 is precision-machined to exact ZF tolerances, ensuring consistent clutch pack engagement under high torque loads. It sits directly between the 4699101080 HOUSING and the 0501329881 HOUSING COVER, forming a sealed chamber that regulates oil flow. Without this genuine GK10 unit, the transmission cannot achieve proper shift timing, leading to drivability issues in excavators and wheel loaders.

Symptoms of Failure

• Delayed or harsh gear engagement – When the 4699.801.094 wears, hydraulic pressure bleeds internally, causing a noticeable lag when shifting from neutral to forward or reverse. This is a common search query for “ZF transmission slow engagement fix.”
• Intermittent gear slipping under load – A worn GK10 allows clutch packs to partially disengage during heavy digging or lifting operations. Operators often report “transmission slipping in third gear” as a primary complaint.
• Contaminated transmission fluid – Internal wear debris from the actuation hub can circulate through the system. This symptom frequently triggers searches for “metal shavings in ZF transmission oil.”
• Erratic shift patterns – The part’s degraded sealing surfaces cause unpredictable pressure spikes, leading to rough upshifts or missed downshifts, especially in cold weather conditions.

Technical Specifications

Compatibility

This 4699.801.094 GK10 is designed for ZF’s WG series powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG210 models used in brands like Liebherr, Caterpillar, and Volvo CE. The part also serves as a replacement in certain 4WG200 and 5WG210 variants. Always verify the transmission serial number against the OEM parts catalog, as the GK10 was updated in 2018 to include improved sealing geometry. For earlier models, the 4699001080 GK10 may be required instead.
