ZF 4616.306.068 INTERMEDIATE PLATE for WG65 | OEM Genuine Part

Overview

The ZF 4616.306.068 INTERMEDIATE PLATE is a critical structural component within the WG65 series transmission, serving as the central mounting interface between the main gear housing and the torque converter assembly. This OEM genuine part ensures precise alignment of planetary gear sets and hydraulic circuits. The SKU 4616.306.068 is machined from high-strength cast iron to withstand extreme torsional loads and thermal expansion during heavy-duty operations. Without this plate, the transmission cannot maintain proper gear spacing or oil flow distribution.

Symptoms of Failure

• Oil leaks between housing sections: A warped or cracked intermediate plate causes transmission fluid to seep past the mating surfaces, often visible as drips near the bell housing.
• Gear slipping under load: When the plate loses its flatness tolerance, clutch pack clearances shift, leading to delayed engagement or complete loss of drive in forward gears.
• Metallic grinding noises: Fractured mounting lugs allow the plate to shift, causing gear teeth to contact the TRANSMISSION HOUSING during rotation.
• Overheating transmission fluid: Distorted oil galleries restrict hydraulic flow, resulting in elevated sump temperatures and burnt clutch plates.

Technical Specifications

Compatibility

This intermediate plate is specifically engineered for the WG 65 Series transmission family, including models WG180, WG200, and WG250. It is also compatible with certain WG65 variants used in ZF’s off-highway and construction equipment applications. Always verify the casting number on your existing plate before ordering. The plate interfaces directly with the TRANSMISSION HOUSING and is secured using HEXAGON SCREW (M10x30), HEXAGON SCREW (M10x45), and HEXAGON SCREW (M12x50) fasteners.
