Overview
The ZF 4657.183.210 LOOSE PARTS for WG211 is a critical internal fastener and alignment kit designed to secure key sub-assemblies within the transmission housing. This OEM genuine part, identified by SKU 4657.183.210, includes the necessary bolts, washers, and positioning elements that anchor the TRANSMISSION HOUSING to the HOUS.FRONT SECT and the HOUSING REAR PART. Without this loose parts set, the structural integrity of the WG 211 series gearbox is compromised, leading to misalignment of rotating components.
Symptoms of Failure
- Transmission oil seepage at housing joints: When the 4657.183.210 fasteners lose torque, gaps form between the front and rear housing sections, allowing ATF to weep out during operation.
- Intermittent gear engagement hesitation: Loose housing bolts cause the CYLINDRICAL PIN to shift, resulting in delayed or clunky shifts under load.
- Vibration during torque converter lockup: A missing or fatigued bolt from this kit permits micro-movement of the housing, transmitting resonance through the driveline.
- Metallic debris in the oil pan: Worn loose parts can fracture, sending small steel fragments into the sump, often mistaken for gear tooth failure.

Compatibility
This loose parts kit is engineered specifically for the WG 211 Series transmission family. It is also compatible with the following ZF models that share the same housing architecture: WG180, WG200, WG210, and WG220. Always verify the housing casting number before installation, as the HOUS.FRONT SECT and HOUSING REAR PART must match the bolt pattern of this kit. The set is not backward-compatible with pre-1998 WG150 units.
