ZF 4657.183.161 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.161 LOOSE PARTS kit is an OEM genuine service package specifically engineered for the WG 210 Series transmission. This assembly consolidates critical fasteners, seals, and positioning elements required to secure internal sub-assemblies within the gearbox. As a loose parts set, it provides all the necessary hardware to reattach the TRANSMISSION HOUSING and the HOUS.FRONT SECT during a major overhaul. The SKU 4657.183.161 is a direct factory replacement, ensuring that every bolt, washer, and pin meets ZF’s exact torque and metallurgy standards. Without this kit, reassembly of the WG210’s main casing is impossible, making it indispensable for any rebuild or repair project.

Symptoms of Failure

When the components within the 4657.183.161 loose parts set degrade or are lost, operators will notice distinct operational issues. Oil seepage at the transmission housing joint is the most common symptom, often caused by worn sealing surfaces or missing fasteners. A second indicator is gear engagement hesitation or grinding, which occurs when the HOUSING REAR PART shifts out of alignment due to loose bolts. Third, abnormal vibration during load shifts suggests that the CYLINDRICAL PIN has sheared or backed out, allowing internal components to drift. Finally, intermittent loss of hydraulic pressure can result from a loose oil feed passage, directly traceable to missing cap screws from this kit.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the ZF WG 210 Series transmission, but it also fits select variants within the WG180 and WG200 families. The kit’s fasteners and pins are dimensionally identical to those used in the WG180 (up to serial number 45000) and the WG200 (all revisions). For the WG210, it is the only approved service kit for securing the TRANSMISSION HOUSING and HOUS.FRONT SECT. Always verify your transmission’s serial number against ZF’s parts catalog before ordering, as later WG210 units may require an updated kit.
