Overview
The ZF 4657.183.119 LOOSE PARTS for WG210 is a critical OEM genuine component designed to secure and align internal assemblies within the WG 210 series transmission. This part number, 4657.183.119, functions as a precision-engineered fastener kit that ensures the structural integrity of the gear train and hydraulic control units. It sits directly within the transmission’s main casing, interfacing with the TRANSMISSION HOUSING to prevent unwanted movement of shafts and clutches during high-torque operations. Without this loose parts set, the transmission’s internal geometry can shift, leading to premature wear on adjacent components.
Symptoms of Failure
- Intermittent gear slippage under load: When the 4657.183.119 loose parts degrade, the clutch packs lose their precise alignment, causing the transmission to slip out of gear during acceleration—a common long-tail search query for “ZF WG210 slipping under load.”
- Metallic rattling from the bell housing: Worn fasteners allow the HOUS.FRONT SECT to vibrate against the main casing, producing a distinct rattle that intensifies with engine RPM.
- Hydraulic fluid seepage at casing joints: Loose parts compromise the seal between the HOUSING REAR PART and the main body, leading to slow oil leaks that leave puddles under the vehicle after extended idle.
- Erratic shift timing: A failing 4657.183.119 set disrupts the valve body’s mounting stability, causing delayed or harsh shifts that are often searched as “ZF transmission shift hesitation fix.”

Compatibility
This OEM genuine part is specifically engineered for the ZF WG 210 series, but it also shares mounting patterns with the WG180, WG200, and WG250 models due to identical housing bore dimensions. It is a direct replacement for the loose parts set used in the CYLINDRICAL PIN alignment system found in these transmissions. Always verify your transmission’s serial number before ordering, as minor revisions in later WG210 variants may require additional shimming.

Frequently Asked Questions
Q: Can I use the 4657.183.119 loose parts in a ZF WG180 transmission?
A: Yes, this part is cross-compatible with WG180, WG200, and WG250 models, as the mounting hole pattern and thread pitch are identical across these series. However, always confirm your housing casting number matches the OEM reference.
Q: How do I know if my loose parts set is failing?
A: The most common indicators are a persistent oil leak near the HOUSING REAR PART joint and a clunking noise during gear engagement. Inspect the CYLINDRICAL PIN for wear marks if you suspect misalignment.
Q: Is the 4657.183.119 a complete kit or individual fasteners?
A: It is a loose parts set containing multiple fasteners and alignment components, not a single bolt. It includes the necessary hardware to secure the TRANSMISSION HOUSING assembly without requiring separate purchases.
