ZF 4644.231.023 OIL LEVEL TUBE for WG180 | OEM Genuine Part

Overview

The ZF 4644.231.023 OIL LEVEL TUBE is a precision-engineered component designed specifically for the WG180 series transmission. This genuine OEM part ensures accurate fluid level monitoring within the transmission sump, preventing both overfilling and underfilling that can compromise hydraulic pressure and gear engagement. Positioned along the side of the TRANSMISSION HOUSING, the tube provides a direct reading path for oil level checks. The SKU 4644.231.023 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal and reliable performance in heavy-duty industrial applications.

Symptoms of Failure

• Oil leaks around the tube base or connection point: A cracked or corroded oil level tube often results in visible fluid seepage, leading to low transmission oil levels and potential overheating.
• Inaccurate oil level readings causing gear slipping: When the tube becomes blocked or deformed, operators cannot verify proper fluid volume, which may cause intermittent gear slippage under load.
• Contaminated fluid entering the transmission: A broken tube seal allows dirt and moisture to bypass the O-RING and enter the system, accelerating wear on internal components.
• Difficulty during routine maintenance: A warped or damaged tube prevents proper dipstick insertion or sight glass clarity, complicating scheduled fluid checks.

Technical Specifications

Compatibility

This oil level tube is primarily engineered for the ZF WG180 series transmissions. It is also compatible with the WG200 series when used with the appropriate OUTPUT FLANGE and DISCONNECTION assembly. For installations requiring secure fastening, pair this tube with a HEXAGON SCREW (M8 x 20 mm) to ensure proper torque and vibration resistance. Always verify fitment against your transmission’s serial number before ordering.
