Overview
The ZF 4657.183.004 LOOSE PARTS set is a critical service kit designed for the WG 210 series transmission. This assembly contains the necessary loose components—such as seals, retaining rings, and small hardware—required to secure and align internal sub-assemblies during a rebuild or overhaul. Positioned within the main gear train housing, this kit ensures that the TRANSMISSION HOUSING and its adjoining sections remain properly sealed and structurally sound. The SKU 4657.183.004 is an OEM genuine part, guaranteeing exact fitment and material compatibility with the WG210 platform.
Symptoms of Failure
- Oil leaks at the housing joint: When the loose parts wear or become misaligned, transmission fluid can seep between the HOUS.FRONT SECT and the main case, leading to low fluid levels and potential overheating.
- Gear slipping under load: Worn retaining components can cause the HOUSING REAR PART to shift slightly, disrupting gear engagement and producing intermittent slipping during acceleration.
- Unusual rattling or vibration: A loose CYLINDRICAL PIN within the assembly can create a metallic rattle at low RPM, often mistaken for bearing noise.
- Hard shifting or delayed engagement: Degraded loose parts can alter the alignment of the valve body and clutch packs, resulting in harsh or delayed shifts.

Frequently Asked Questions
Q: Can the 4657.183.004 kit be used on a WG180 transmission?
A: Yes, the loose parts kit is cross-compatible with WG180, WG200, and WG210 models, provided the housing sections are original ZF parts. Always inspect the HOUSING REAR PART for wear before installation.
Q: What is the typical service interval for replacing these loose parts?
A: ZF recommends replacing the 4657.183.004 kit during any major transmission overhaul or when oil leaks are detected at the housing seams. The CYLINDRICAL PIN should be replaced every 500,000 km to maintain alignment.
Q: Does this kit include the cap screws shown in the related components table?
A: No, the 4657.183.004 kit contains only the loose parts (pins, seals, clips). Cap screws like 0636100801 and 0636100803 must be ordered separately if needed.
