ZF 4642.131.200 FILLER NOZZLE for WG150 | OEM Genuine Part

Overview

The ZF 4642.131.200 FILLER NOZZLE is a precision-engineered fluid delivery component designed exclusively for the WG 150 series transmission. This OEM genuine part serves as the primary oil fill point, channeling transmission fluid directly into the main sump via the TRANSMISSION HOUSING assembly. Constructed from corrosion-resistant alloy, the nozzle ensures a secure, leak-free interface between the fill tube and the transmission case. The SKU 4642.131.200 is machined to exact ZF tolerances, guaranteeing proper fluid flow and preventing contamination during service intervals.

Symptoms of Failure

• Transmission fluid seepage around the fill port: A worn or cracked filler nozzle often causes slow oil leaks at the top of the transmission housing, leading to low fluid levels and eventual overheating.
• Hard shifting or gear slipping during acceleration: When the nozzle fails to seal, air enters the hydraulic circuit, causing erratic clutch engagement and delayed shifts in WG150 units.
• Visible fluid spray or mist under the hood: A fractured filler nozzle can eject pressurized oil onto adjacent components, such as the TRANSMISSION HOUSING, creating a slippery hazard and accelerating belt wear.
• Difficulty filling transmission fluid: A deformed or blocked nozzle prevents proper insertion of fill equipment, leading to under-filling and subsequent transmission damage.

Technical Specifications

Compatibility

This filler nozzle is specifically engineered for the ZF WG 150 series, but it also fits select variants of the WG 180 and WG 200 transmissions where the fill port geometry matches. The part integrates directly with the TYPE PLATE mounting area and is secured using the GROOVED STUD for vibration resistance. Always verify your transmission model’s housing casting number before installation.
