ZF 4660.231.011 OIL FILLER PIPE for WG92 | OEM Genuine Part

Overview

The ZF 4660.231.011 OIL FILLER PIPE is a critical fluid delivery component engineered specifically for the WG 92 series transmission family. This OEM genuine part serves as the primary conduit for introducing transmission fluid into the main sump, ensuring proper lubrication and hydraulic pressure within the gear train. Mounted directly to the TRANSMISSION HOUSING, this pipe channels oil from the fill port to the internal reservoir without turbulence or aeration. The SKU 4660.231.011 is precision-machined to match ZF’s exacting tolerances, guaranteeing a leak-free seal when paired with the correct O-RING and SCREW PLUG assembly.

Symptoms of Failure

• External oil seepage around the fill neck: A cracked or corroded 4660.231.011 pipe often causes slow fluid loss, leaving visible drips on the transmission housing and undercarriage.
• Difficulty filling or overfilling transmission fluid: A blocked or deformed filler pipe prevents proper fluid flow, leading to inaccurate dipstick readings and potential gear slipping under load.
• Whining or groaning noises during gear engagement: Insufficient oil volume due to a compromised pipe starves the hydraulic system, causing cavitation and audible distress from the valve body.
• Burnt transmission fluid odor: A restricted filler pipe can cause low fluid levels, leading to overheating and accelerated wear on clutches and bands.

Technical Specifications

Compatibility

This oil filler pipe is designed for the ZF WG 92 series, which includes models such as WG92, WG180, WG200, and WG250. It integrates with the HOUSING assembly and is frequently replaced alongside the TUBE and TUBE components for complete fluid circuit restoration. Always verify fitment with your specific transmission serial number before installation.
