Overview
The ZF 4657.183.096 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 series transmission. This OEM genuine part set contains the internal fasteners, positioning elements, and small hardware required to secure major transmission housings and fluid passages during rebuild or repair. The SKU 4657.183.096 is often ordered alongside a new TRANSMISSION HOUSING to ensure all bolts, pins, and plates meet factory torque specifications. Without this loose parts kit, reassembly of the WG210 can lead to misalignment of the HOUS.FRONT SECT and the HOUSING REAR PART, compromising gear train geometry.
Symptoms of Failure
- Oil seepage at housing joints: When the fasteners in this kit fatigue, the seal between the front section and rear housing degrades, causing visible transmission fluid leaks around the bell housing area.
- Intermittent gear slippage under load: A loose CYLINDRICAL PIN from this set can allow the clutch drum to shift axially, resulting in momentary power loss during upshifts.
- Abnormal driveline vibration: Missing or damaged fixing plates from the kit permit the oil screen to rattle, transmitting vibration through the transmission case at highway speeds.
- Hard shifting or delayed engagement: Worn cap screws in the loose parts set can cause the valve body to sit unevenly, disrupting hydraulic pressure timing.

Compatibility
This loose parts kit is engineered for the ZF WG 210 series, but its hardware dimensions also suit the WG180 and WG200 models due to shared housing bolt patterns. It is compatible with all WG210 variants including the WG210-1, WG210-2, and WG210-3. The kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT. For complete assembly, technicians should also verify fitment of the HOUSING REAR PART and the CYLINDRICAL PIN which are frequently replaced concurrently.
