ZF 4644.231.176 OIL LEVEL TUBE for WG200 | OEM Genuine Part

Overview

The ZF 4644.231.176 OIL LEVEL TUBE is a critical fluid management component engineered specifically for the WG200 series transmission. This OEM genuine part ensures precise oil level measurement and proper lubrication circulation within the transmission housing. Located on the side of the main gearbox casing, the tube provides a direct channel for dipstick access while maintaining a sealed environment. The SKU 4644.231.176 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and reliable fluid containment in heavy-duty industrial applications.

Symptoms of Failure

• External oil seepage around the transmission housing – A cracked or degraded tube allows transmission fluid to escape, often visible as wet spots near the dipstick port.
• Inaccurate fluid level readings – When the tube becomes blocked or distorted, the dipstick no longer reflects the true oil level, leading to overfilling or underfilling.
• Gear slipping under load – Insufficient lubrication caused by a compromised tube can result in intermittent power loss or delayed engagement during operation.
• Burning smell from overheated transmission fluid – A failing tube may restrict oil return flow, causing localized overheating and a distinct acrid odor.
