ZF 4642.231.034 OIL LEVEL TUBE for WG150 | OEM Genuine Part

Overview

The ZF 4642.231.034 OIL LEVEL TUBE is a precision-engineered component designed for the WG150 series transmission. This genuine OEM part serves as the critical conduit for monitoring and maintaining proper fluid levels within the transmission sump. Positioned along the side of the main casing, the tube connects directly to the TRANSMISSION HOUSING (part 4642101047) and interfaces with the TRANSMISSION HOUSING (part 4642301207) to ensure accurate oil level readings. The SKU 4642.231.034 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal and reliable fluid management under heavy-duty operating conditions.

Symptoms of Failure

• Visible oil leaks around the transmission housing: A worn or cracked oil level tube often causes fluid to seep from the connection points, leading to low oil levels and potential gear slipping.
• Inaccurate dipstick readings or fluid level fluctuations: When the tube degrades, the internal channel may become blocked or distorted, resulting in false oil level indications that can cause transmission overheating.
• Gear engagement hesitation or slipping under load: Insufficient lubrication due to a compromised tube can lead to delayed shifts and erratic performance, especially during heavy hauling or frequent stop-and-go operations.
• Contaminated transmission fluid from external debris ingress: A broken tube seal allows dirt and moisture to enter the system, accelerating wear on internal components like the GROOVED STUD (part 0631311009).

Technical Specifications

Compatibility
