Overview
The ZF 4657.183.353 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly includes all necessary loose hardware, seals, and fasteners required to secure and align the main transmission housing sections during rebuild or repair. The SKU 4657.183.353 sits at the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring proper clamping force and preventing fluid migration between cavities. Without this loose parts set, the structural integrity of the WG210 assembly is compromised, leading to premature wear of internal components.
Symptoms of Failure
- Transmission fluid seepage at housing joints: When the 4657.183.353 loose parts degrade, you will notice oil weeping between the HOUSING REAR PART and the main casing, especially after thermal cycling.
- Abnormal gear engagement noise: Worn fasteners from this kit allow micro-movement between housing sections, producing a distinct clunking sound during shift transitions under load.
- Intermittent pressure loss in hydraulic circuits: Loose or missing components from the 4657.183.353 set cause misalignment of oil galleries, resulting in erratic clutch pack application and delayed shifts.
- Vibration at the bell housing interface: Degraded hardware leads to uneven clamping, transmitting driveline vibration through the HOUSING REAR SECTION to the chassis.

Compatibility
This 4657.183.353 LOOSE PARTS kit is engineered for the ZF WG 210 series, but it also cross-fits select models in the WG180 and WG200 families due to shared housing architecture. Specifically, it is compatible with WG180, WG200, and WG210 transmissions manufactured after 2008. The kit interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, and it is required when replacing either the HOUSING REAR PART or the HOUSING REAR SECTION. Always verify your transmission serial number before ordering.
