ZF 4642.231.118 OIL LEVEL TUBE for WG150 | OEM Genuine Part

Overview

The ZF 4642.231.118 OIL LEVEL TUBE is a precision-engineered component designed specifically for the WG150 transmission series. This OEM genuine part serves as the primary conduit for monitoring and maintaining proper fluid levels within the transmission sump, ensuring optimal lubrication and hydraulic pressure. Located on the side of the main TRANSMISSION HOUSING, the tube provides a clear visual reference for oil volume, which is critical for preventing overheating and gear wear. The SKU 4642.231.118 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal and long service life in heavy-duty industrial applications.

Symptoms of Failure

• Transmission oil leaks at the tube base: A cracked or corroded oil level tube often causes fluid to seep around the connection point, leading to low oil levels and potential gear damage.
• Inaccurate fluid level readings: When the tube becomes blocked or distorted, operators may overfill or underfill the transmission, resulting in erratic shifting or gear slipping during load changes.
• Visible oil mist or spray near the housing: A compromised tube can allow pressurized oil to escape, creating a fine mist that coats adjacent components like the TRANSMISSION HOUSING and TYPE PLATE.
• Increased transmission operating temperature: Insufficient oil due to tube failure reduces heat dissipation, causing the system to run hotter than normal and accelerating seal degradation.

Technical Specifications

Compatibility

This oil level tube is primarily engineered for the ZF WG150 series, but it also fits select variants within the WG180 and WG200 families due to shared housing architecture. It is a direct replacement for units equipped with the GROOVED STUD mounting system. Always verify your transmission model before ordering; the tube interfaces with the main housing casting and requires proper alignment with the oil pan gasket surface.
