ZF 4657.183.045 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.045 LOOSE PARTS for WG210 is a critical OEM genuine component designed for the internal assembly of ZF WG series transmissions. This specific part number, 4657.183.045, functions as a precision-engineered kit of loose hardware and fasteners that secure the main housing sections together, ensuring proper alignment and sealing under high torque loads. Located within the central casing assembly, these parts work directly with the TRANSMISSION HOUSING to maintain structural integrity. Without this kit, the transmission cannot maintain the necessary clamping force between the HOUS.FRONT SECT and the HOUSING REAR PART, leading to premature wear.

Symptoms of Failure

When the ZF 4657.183.045 LOOSE PARTS begin to degrade or are missing during rebuild, operators will notice distinct failure modes. Oil seepage at the housing split line is the most common indicator, often appearing as wet streaks between the front and rear casing sections. Abnormal gear engagement noise occurs when the fasteners loosen, allowing micro-movement between the CYLINDRICAL PIN alignment points. Intermittent loss of hydraulic pressure can result from distorted sealing surfaces, while vibration during load shifts signals that the housing sections are no longer rigidly coupled. These symptoms typically worsen under heavy-duty applications, making early replacement essential.

Technical Specifications

Compatibility

This loose parts kit is specifically engineered for the WG 210 Series transmission family. Based on the part type and fastener geometry, it is also compatible with the WG180 and WG200 models that share the same housing bolt pattern. The kit is not recommended for WG150 or WG250 variants without cross-referencing the TRANSMISSION HOUSING dimensions. Always verify the presence of the HOUS.FRONT SECT and HOUSING REAR PART to confirm fitment. The CYLINDRICAL PIN included in this kit is a universal alignment component across the WG series.
