ZF 0501.326.930 STEERING GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.326.930 STEERING GEAR is a critical OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This part functions as the primary control mechanism for directing hydraulic flow within the gearbox, ensuring precise engagement and disengagement of gear sets. Positioned within the valve body assembly, the steering gear (SKU: 0501.326.930) directly interfaces with the main housing to regulate shift timing and pressure. For optimal sealing and structural integrity, this component is installed alongside the 4699101049: HOUSING and the 4699301188: HOUSING, which provide the necessary mounting surfaces and fluid channels.

Symptoms of Failure

When the ZF 0501.326.930 steering gear begins to wear, operators will notice distinct performance degradation. Common failure indicators include:

• Erratic gear engagement or delayed shifting – The steering gear loses its ability to modulate hydraulic pressure, causing rough or unpredictable gear changes.
• Internal oil leaks around the valve body – Worn seals on the steering gear allow transmission fluid to bypass, often pooling near the 4699301128: COVER.
• Transmission slipping under load – A failing steering gear cannot maintain consistent line pressure, leading to power loss during acceleration.
• Unusual whining or grinding noises – Metal-on-metal contact within the steering mechanism generates audible distress signals, especially in cold start conditions.

Technical Specifications

Compatibility

This steering gear is specifically designed for ZF’s WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It may also be retrofitted into WG180 and WG200 series with minor modifications to the 0636015047: HEXAGON SCREW mounting pattern. Always verify housing alignment using the 4699101049: HOUSING as a reference point.
