Overview
The ZF 4657.183.357 LOOSE PARTS kit is a critical service package designed specifically for the WG 210 Series transmission. This genuine OEM assembly contains the necessary loose components—including seals, retaining rings, and small hardware—required to properly secure and seal internal transmission assemblies during a rebuild or overhaul. Positioned within the main gear train housing, this kit ensures that the TRANSMISSION HOUSING maintains its structural integrity and prevents fluid migration between chambers. The SKU 4657.183.357 is the factory-specified solution for restoring original performance in ZF WG210 units, eliminating the need to source individual fasteners and spacers separately.
Symptoms of Failure
- Transmission fluid seepage at housing joints: When the loose parts in this kit degrade, you may notice oil weeping from the seam between the HOUS.FRONT SECT and the main casing, indicating worn gaskets or retaining clips.
- Intermittent gear engagement hesitation: A loose or missing internal fastener can cause slight axial play in the shaft assembly, leading to delayed or rough shifting under load.
- Unusual metallic rattling from the bell housing: If the retaining hardware for the HOUSING REAR PART becomes loose, components may vibrate against the housing, producing a distinct rattle at idle.
- Speedometer signal dropout: A failing retaining clip in this kit can cause the SPEEDOMETER drive gear to lose alignment, resulting in erratic or zero speed readings.

Compatibility
This genuine ZF 4657.183.357 LOOSE PARTS kit is engineered exclusively for the WG 210 Series transmission. It is also compatible with select variants in the WG180 and WG200 families that share the same housing architecture, specifically those using the TRANSMISSION HOUSING and rear section designs. Always verify your transmission model tag before ordering. For units requiring additional fastening hardware, the CAP SCREW (0636100801) and CYLINDRICAL PIN (0631306792) are commonly paired with this kit during reassembly.
