ZF 4644.306.598 PLATE for WG150 | OEM Genuine Part

Overview

The ZF 4644.306.598 PLATE is a precision-engineered component designed for the WG150 series transmission. This OEM genuine part functions as a critical interface element within the clutch or valve body assembly, ensuring proper fluid distribution and mechanical alignment under high-torque conditions. The SKU 4644.306.598 is manufactured to exact ZF tolerances, providing a direct replacement that maintains original equipment performance. When installed alongside a TRANSMISSION HOUSING or a TRANSMISSION HOUSING, this plate ensures secure sealing and structural integrity within the gear train.

Symptoms of Failure

• Erratic gear engagement or slipping under load: A worn 4644.306.598 plate can cause inconsistent hydraulic pressure, leading to delayed or rough shifting, especially in heavy-duty applications.
• Transmission fluid leaks near the housing interface: Degradation of the plate’s sealing surface often results in visible oil seepage around the TYPE PLATE area, requiring immediate inspection.
• Unusual metallic noise during gear changes: If the plate becomes warped or develops cracks, it may produce a grinding or clattering sound as it contacts adjacent components like the GROOVED STUD.
• Reduced transmission efficiency and overheating: A failing plate disrupts oil flow, causing elevated operating temperatures and potential damage to internal assemblies.

Technical Specifications

Compatibility

This plate is primarily engineered for the ZF WG150 transmission series. Based on its design and mounting pattern, it is also compatible with the WG180, WG200, and WG210 models that share the same hydraulic circuit architecture. For proper fitment, verify that the SHIFT SYSTEM and VALVE BLOCK in your assembly match the OEM specifications for the 4644.306.598 plate.
