Overview
The ZF 4657.183.362 LOOSE PARTS kit is a critical service set designed specifically for the WG 210 series transmission. This OEM genuine assembly includes all necessary fasteners, seals, and positioning elements required to secure and align the main structural components of the gearbox. Positioned at the junction between the HOUS.FRONT SECT and the HOUSING REAR PART, this kit ensures proper clamping force and oil-tight integrity. The SKU 4657.183.362 is a factory-original loose parts bundle, meaning each component is individually packaged to prevent cross-contamination during rebuilds. Without this specific kit, the transmission housing assembly cannot maintain its structural rigidity under high torque loads.
Symptoms of Failure
- Oil seepage at the housing split line: When the loose parts in kit 4657.183.362 degrade or are improperly torqued, transmission fluid will weep between the TRANSMISSION HOUSING and the rear section, leaving visible drips on the bell housing.
- Abnormal gear engagement noise: Worn or missing fasteners from this kit allow micro-movement between the HOUSING REAR SECTION and the main case, producing a distinct metallic clatter during 2-3 shift transitions.
- Intermittent loss of hydraulic pressure: A compromised seal from this loose parts set causes internal cross-leakage, resulting in delayed clutch pack engagement and erratic shift timing under load.
- Visible fastener corrosion or stripping: The cap screws and cylindrical pins in this kit are prone to galvanic corrosion in wet environments, leading to stripped threads and loose housing joints.

Compatibility
This OEM genuine part is engineered for the ZF WG 210 transmission family, but its loose parts configuration also applies to the WG180, WG200, and WG250 series due to shared housing bolt patterns. The kit specifically interfaces with the TRANSMISSION HOUSING and the rear structural sections. It is not compatible with the Ecomat or Ecolife series. Always verify the housing casting number before ordering; the 4657.183.362 kit is designed for transmissions with a 6-bolt rear cover pattern.
