ZF 4699.005.010 GK30 | OEM Genuine Part

Overview

The ZF 4699.005.010 GK30 is a critical OEM genuine component designed for heavy-duty construction machinery transmissions. This part functions as a precision-machined gear kit or shift assembly within the transmission housing, directly influencing gear engagement and torque transfer. Positioned in the upper valve body or clutch pack area of ZF powershift transmissions, the SKU 4699.005.010 ensures smooth hydraulic flow and mechanical synchronization. When paired with the 4699101044 HOUSING and 4699301111 HOUSING, this part forms the core of the shift control system, reducing wear on adjacent components.

Symptoms of Failure

• Delayed or harsh gear engagement: When the 4699.005.010 wears, operators often notice a lag between shifting and actual gear change, especially under load. This is a common long-tail search query for “ZF transmission slow engagement fix.”
• Hydraulic fluid contamination: Worn internal surfaces can shed metallic debris into the oil, leading to clogged filters and erratic pressure. Search for “metal shavings in ZF transmission oil” often points to this part.
• Intermittent slipping under torque: As the GK30 loses dimensional tolerance, the transmission may slip during heavy digging or climbing, a symptom frequently searched as “powershift transmission slipping under load.”
• Unusual whining or grinding noise: A high-pitched noise from the transmission housing during neutral-to-drive shifts indicates this component is failing, matching queries like “ZF transmission whining noise repair.”

Technical Specifications

Compatibility

This OEM genuine part is engineered for ZF powershift transmissions commonly used in construction machinery, including the WG180, WG200, and WG210 series. It also fits select models of the 4WG-200 and 6WG-200 transmissions found in wheel loaders, dozers, and excavators. For proper installation, ensure the 4699301054 HOUSING COVER and 4699301055 COVER are inspected for wear simultaneously, as these components share the same hydraulic circuit. Always verify your transmission serial number against ZF application charts before ordering.
