Overview
The ZF 2094.306.001 SWIVEL SCREW is a precision-engineered OEM genuine fastener designed for the hydraulic control assemblies within ZF WG100, WG130, and WG131 transmissions. This swivel screw acts as a critical pivot point and sealing interface, allowing fluid to pass through a rotating joint without leakage. It is commonly found in the valve body or clutch piston circuit, where it secures a hydraulic line while maintaining a leak-proof seal under high pressure. The SKU 2094.306.001 is manufactured to ZF’s exacting tolerances, ensuring reliable oil flow and preventing cross-threading during installation. When paired with a 0631329086 SPRING PIN, this assembly provides a vibration-resistant connection that withstands the thermal cycling of heavy-duty industrial transmissions.
Symptoms of Failure
- Hydraulic fluid seepage at the valve body joint: A worn swivel screw often causes slow oil leaks around the transmission housing, leading to low fluid levels and erratic shift quality.
- Intermittent gear engagement or slipping: When the swivel screw fails to maintain a sealed connection, pressure drops in the clutch circuit, resulting in delayed or incomplete gear engagement under load.
- Metallic debris in the transmission pan: A fractured swivel screw can shed small metal fragments that contaminate the oil, accelerating wear on adjacent components like the 0750117075 TAPER ROLLER BEARING.
- Audible clicking or rattling from the transmission: Loose swivel screws create a distinct noise during gear changes, often mistaken for worn differentials such as the 5838109007 DIFFERENTIAL assembly.

Compatibility
This swivel screw is specifically designed for the ZF WG series of powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It may also fit WG180 and WG200 transmissions where the valve body uses the same hydraulic port geometry. For differential-related assemblies, always verify fitment with the 2095209019 DIFFERENTIAL unit, as variations in housing thickness can affect screw length requirements.
