ZF 4642.302.006 COVER for WG 150 | OEM Genuine Part

Overview

The ZF 4642.302.006 COVER is a critical sealing and protective component engineered specifically for the WG 150 series transmission. This OEM genuine part mounts directly to the main transmission housing, serving as a barrier against contamination and fluid loss while maintaining internal pressure integrity. As a precision-machined cover, it interfaces with the shift mechanism and valve body area, ensuring that the transmission’s internal environment remains stable under high-torque industrial applications. The SKU 4642.302.006 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged covers in heavy-duty drivelines.

Symptoms of Failure

• External oil seepage around the cover perimeter: When the 4642.302.006 gasket surface degrades, transmission fluid escapes, leaving visible wet spots on the housing. This is a common long-tail search query for “ZF WG150 cover oil leak repair.”
• Gear engagement hesitation or slipping: A compromised cover can allow debris ingress or pressure loss, leading to delayed shifts or clutch pack slippage during load changes.
• Abnormal transmission noise: Loose or cracked covers vibrate against the TRANSMISSION HOUSING, producing a distinct rattling or humming sound at operating RPM.
• Visible corrosion or warping: Prolonged exposure to heat cycles causes the cover to distort, breaking the seal with the TRANSMISSION HOUSING and accelerating fluid contamination.

Technical Specifications

Compatibility

This cover is primarily designed for the ZF WG 150 series transmission, but it also fits select models in the WG180 and WG200 families where the cover mounting pattern matches. It is commonly used in municipal trucks, construction loaders, and agricultural tractors. For proper fitment, always verify the housing interface against the TYPE PLATE affixed to your transmission, which lists the exact series and revision. The cover secures using GROOVED STUD fasteners, ensuring consistent clamping force across the mating surface.
