Overview
The ZF 4657.183.047 LOOSE PARTS for WG210 is a genuine OEM service kit designed to restore the internal integrity of your ZF WG 210 Series transmission. This assembly-level component contains the critical loose hardware and small parts necessary for a complete rebuild or selective replacement within the valve body and clutch pack area. Specifically, the SKU 4657.183.047 includes retaining clips, sealing rings, and positioning elements that secure the TRANSMISSION HOUSING to the HOUS.FRONT SECT. Without these loose parts, the main housing assembly cannot maintain proper hydraulic pressure or mechanical alignment.
Symptoms of Failure
- Intermittent gear slippage under load: When the loose parts within the 4657.183.047 kit wear or break, the clutch piston travel becomes inconsistent, causing the transmission to slip during acceleration.
- Low hydraulic pressure at the main regulator valve: Damaged sealing rings from this kit allow fluid to bypass, resulting in a delayed or harsh shift pattern.
- Metallic debris in the transmission pan: Fractured retaining clips from the 4657.183.047 assembly can shed small metal fragments, contaminating the oil and damaging the CYLINDRICAL PIN bores.
- Oil weeping from the housing joint: A failed gasket or loose fastener within this kit causes external leaks where the HOUSING REAR PART meets the main case.

Compatibility
This genuine ZF 4657.183.047 loose parts kit is engineered for the WG 210 Series, but it also fits the WG180, WG200, and WG250 models that share the same valve body architecture. The kit is essential when replacing the TRANSMISSION HOUSING or servicing the HOUS.FRONT SECT. Always verify the CYLINDRICAL PIN alignment before installation. For WG210 units built after 2010, confirm the HOUSING REAR PART revision matches your serial number.
