Overview
The ZF 4657.183.410 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 210 series transmission. This assembly group contains the essential loose hardware and small components required to secure and align the main structural elements of the gearbox during a rebuild or major repair. The SKU 4657.183.410 sits within the transmission’s core housing assembly, acting as the fastening and positioning interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT. Without this genuine parts kit, proper torque retention and alignment of the HOUSING REAR PART and the HOUSING REAR SECTION cannot be guaranteed, leading to premature wear.
Symptoms of Failure
When the components within the 4657.183.410 kit degrade or are missing, operators will notice distinct operational issues. The most common failure symptom is transmission fluid seepage at the housing mating faces, often mistaken for a gasket failure. A second critical sign is abnormal gear engagement noise or clunking during shifts, caused by loose fasteners allowing housing sections to shift. Third, you may experience intermittent loss of hydraulic pressure due to misalignment of internal oil passages. Finally, vibration at the bell housing during acceleration indicates that the loose parts have fatigued, compromising the structural integrity of the WG210 assembly.

Compatibility
This OEM genuine loose parts kit is engineered for the ZF WG 210 series, but its application extends to several closely related transmission models. The 4657.183.410 is directly compatible with the WG180, WG200, and WG210 series gearboxes. It is also suitable for select variants of the WG150 and WG250 where the housing bolt pattern matches. Always verify the specific housing casting numbers before installation, particularly when mating the HOUS.FRONT SECT to the HOUSING REAR PART.
