ZF 4616.306.127 COVER PLATE for WG65 | OEM Genuine Part

Overview

The ZF 4616.306.127 COVER PLATE is a critical sealing and protective component engineered specifically for the WG 65 Series transmission. Positioned on the exterior of the gearbox housing, this OEM genuine part safeguards internal assemblies from contamination while maintaining proper oil retention. The SKU 4616.306.127 serves as a direct replacement for worn or damaged cover plates, ensuring the structural integrity of the transmission’s rear section. When installed correctly, it works in concert with the 4616105402: OUTPUT and the 4005303005: OUTPUT FLANGE to create a sealed, high-torque interface.

Symptoms of Failure

• External oil seepage around the rear cover: A degraded cover plate gasket or warped metal can cause transmission fluid to leak from the WG65 housing, often visible as drips under the vehicle after operation.
• Increased gear engagement noise: When the cover plate loses its rigidity, it can allow slight misalignment of the output shaft, leading to a whining or grinding sound during gear shifts.
• Contamination ingress near the output flange: A cracked or corroded cover plate permits dirt and moisture to enter the transmission, accelerating wear on the 4616101119: TRANSMISSION HOUSING and internal bearings.
• Vibration at the driveline connection: Loose or fatigued mounting points on the cover plate can transmit abnormal vibrations through the 0636011038: HEXAGON SCREW fasteners, indicating imminent failure.

Technical Specifications

Compatibility

This cover plate is primarily designed for the ZF WG 65 Series transmissions, including models such as WG65, WG80, and WG100. It is also compatible with select WG120 and WG150 variants where the rear housing interface matches the 210mm bolt pattern. For proper fitment, verify that the 0636011118: HEXAGON SCREW and 0636016015: HEXAGON SCREW fasteners are used during installation. The plate integrates directly with the 0631306085: CYLINDRICAL PIN for alignment and the 0634313118: O-RING for sealing. Additionally, the 0636304019: SCREW PLUG and 0634801152: SEALING RING are often replaced concurrently to ensure a leak-free assembly.
