ZF 4699.001.167 GK10 | OEM Genuine Part

Overview

The ZF 4699.001.167 GK10 is a genuine OEM component engineered for the hydraulic control system within ZF heavy-duty powershift transmissions. This part functions as a critical valve or shift element, directing oil flow to engage specific gear sets under load. It sits within the transmission valve body assembly, directly interfacing with the HOUSING to regulate clutch pack pressure. The SKU 4699.001.167 is precision-machined to OEM tolerances, ensuring reliable shift timing and torque delivery in construction machinery applications.

Symptoms of Failure

When the ZF 4699.001.167 wears out, operators often notice these specific failure modes:

• Erratic gear engagement or delayed shifting – The part loses hydraulic sealing, causing sluggish clutch fill times during direction changes.
• Internal transmission oil leaks – Worn sealing surfaces allow pressurized oil to bypass, often pooling around the HOUSING COVER joint.
• Torque converter shudder under load – Inconsistent pressure regulation leads to clutch slip, particularly in low-range gears on excavators or loaders.
• Overheating transmission fluid – Continuous slip generates excess heat, accelerating degradation of the O-RING seals.

Technical Specifications

Compatibility

This genuine ZF 4699.001.167 GK10 is designed for use in the following ZF transmission models commonly found in construction machinery:

• ZF WG180 – Wheel loader and grader applications
• ZF WG200 – Medium-duty articulated dump trucks
• ZF 4WG200 – Four-speed powershift variants
• ZF 6WG250 – Heavy-duty excavator and dozer transmissions

Always verify the BREATHER condition during replacement, as a clogged breather can cause pressure imbalances that accelerate wear on this valve component.
