Overview
The ZF 4657.183.352 LOOSE PARTS set is a critical service kit designed specifically for the WG210 series transmission. This OEM genuine part contains the essential fasteners, seals, and positioning components required to secure and align the main transmission housing sections during rebuild or repair. The SKU 4657.183.352 is typically installed during the final assembly phase, ensuring that the TRANSMISSION HOUSING maintains proper structural integrity under load. Without this loose parts kit, the internal gear train cannot be correctly seated, leading to premature wear of the entire WG210 assembly.
Symptoms of Failure
- Transmission oil leaks at housing seams: When the 4657.183.352 fasteners loosen or corrode, oil seeps between the HOUS.FRONT SECT and the main body, causing visible drips and low fluid levels.
- Gear slipping under moderate load: Worn or missing loose parts allow the HOUSING REAR PART to shift slightly, misaligning the clutch packs and causing intermittent power loss.
- Abnormal vibration during shifting: A degraded loose parts kit fails to dampen resonance between the HOUSING REAR SECTION and the output shaft, producing a low-frequency shudder.
- Difficulty engaging reverse gear: Misalignment from compromised fasteners prevents the selector mechanism from fully engaging the reverse planetary set.

Compatibility
This genuine ZF loose parts kit is engineered for the WG210 series but also fits the WG180, WG200, and WG250 models due to shared housing bolt patterns. It is directly compatible with the CYLINDRICAL PIN (0631306816) used for alignment and the CAP SCREW (0636100801) for final fastening. Always verify your transmission serial number against the WG210 parts catalog before ordering.

Frequently Asked Questions
Q: Can I reuse the original fasteners from my old transmission instead of buying the 4657.183.352 kit?
A: No. ZF specifies that all loose parts in this kit are single-use due to torque-to-yield design. Reusing them risks fastener fatigue and oil leaks.
Q: Does this kit include the screen sheets for the oil filter?
A: No. The 4657.183.352 kit contains only fasteners, pins, and seals. For filter screens, order 4657301032 or 4657301033 separately.
Q: Will this part work with a WG210 transmission built before 2010?
A: Yes, the 4657.183.352 is backward compatible with all WG210 variants, but verify that your TRANSMISSION HOUSING has the updated bolt pattern introduced in 2005.
