ZF 0736.304.024 SCREW PLUG for WG65 | OEM Genuine Part

Overview

The ZF 0736.304.024 SCREW PLUG is a precision-engineered sealing component designed specifically for the WG 65 series heavy-duty transmission. This OEM genuine part functions as a critical closure point within the transmission housing, preventing fluid loss and maintaining internal pressure integrity. Positioned typically in the lower sump or side access ports of the WG65 gearbox, the 0736.304.024 screw plug ensures that lubricating oil remains contained during high-torque operations. When installed alongside the 4616101066 TRANSMISSION HOUSING, this plug creates a reliable seal that withstands extreme thermal cycling and vibration. The SKU 0736.304.024 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged plugs in commercial vehicle and industrial powertrain applications.

Symptoms of Failure

• Oil seepage around the plug head: A worn or stripped 0736.304.024 screw plug often causes visible oil weeping, especially after extended idle periods or under heavy load.
• Transmission fluid level drop without external puddles: When the plug loses its sealing edge, fluid may escape as a fine mist, leading to gradual level loss and potential gear slipping.
• Corrosion or thread galling on removal: Failed plugs frequently exhibit rust or aluminum transfer, making future service difficult and risking damage to the 0636011118 HEXAGON SCREW mounting points.
• Increased operating noise from low lubricant: A compromised seal allows air ingress, aerating the oil and reducing hydraulic pressure, which manifests as whining or clattering from the WG65 gear train.

Technical Specifications

Compatibility

This screw plug is engineered for the ZF WG 65 series, but its thread pattern and sealing geometry also suit several other ZF commercial transmissions. Compatible models include the WG180, WG200, WG210, and WG250 series, where the plug serves as a drain or fill port closure. It is also used in select ZF Ecolife and AS Tronic mid-range gearboxes. For proper fitment, always verify the thread pitch and housing depth against your specific unit. The plug works in conjunction with the 4616301307 HOUSING and 4616301309 HOUSING assemblies, which share identical port dimensions on the WG65 platform.
