ZF 4642.121.017 OIL PIPE for WG150 | OEM Genuine Part

Overview

The ZF 4642.121.017 OIL PIPE is a precision-engineered fluid conduit designed for the WG 150 Series transmission. This OEM genuine part ensures consistent lubrication and hydraulic pressure delivery to critical internal components, including the clutch packs and valve body. By maintaining a steady flow of transmission fluid, the 4642.121.017 oil pipe prevents overheating and reduces friction during gear shifts. Installed within the lower valve body assembly, this part works in tandem with the 4642101109: TRANSMISSION HOUSING to seal the hydraulic circuit. The SKU 4642.121.017 is a direct replacement for original equipment, guaranteeing a perfect fit without modifications.

Symptoms of Failure

• Transmission fluid leaks near the oil pan: A cracked or corroded 4642.121.017 oil pipe often causes visible drips or puddles under the vehicle, especially after prolonged operation.
• Delayed or harsh gear engagement: When this pipe becomes blocked or deformed, hydraulic pressure drops, leading to sluggish shifts or sudden clunking noises.
• Overheating transmission: Restricted oil flow through a damaged pipe reduces cooling efficiency, triggering warning lights or burnt fluid odors.
• Low fluid level without external leaks: Internal cracks in the pipe can divert oil into the 4642301205: TRANSMISSION HOUSING cavity, causing gradual fluid loss without visible drips.

Technical Specifications

Compatibility

This oil pipe is primarily engineered for the ZF WG 150 Series, but it also fits select variants of the WG 180 and WG 200 transmissions due to shared hydraulic architecture. It is compatible with models manufactured between 2005 and 2020. For proper installation, ensure the 0730365125: TYPE PLATE is inspected to confirm transmission series, and use the 0631311009: GROOVED STUD for secure mounting. Always verify fitment with your transmission’s serial number before ordering.
