Overview
The ZF 4657.183.088 LOOSE PARTS kit is a critical service component engineered specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential fasteners, seals, and positioning elements required to secure internal sub-assemblies within the gearbox. As a maintenance-intensive part, the 4657.183.088 ensures that the TRANSMISSION HOUSING remains properly aligned with the HOUS.FRONT SECT and the HOUSING REAR PART. Without this loose parts set, the transmission cannot maintain its structural integrity under load. The SKU 4657.183.088 is factory-matched to WG210 units and should be replaced whenever the main housing is disassembled for overhaul.
Symptoms of Failure
- Oil seepage at housing joints: When the loose parts kit degrades, the seals between the transmission housing and front section fail, causing fluid to weep from the mating surfaces. This is a common long-tail search query for “ZF WG210 oil leak repair.”
- Intermittent gear slippage under load: Worn fasteners or missing positioning pins allow the rear housing part to shift slightly, leading to misalignment of the clutch packs. Operators often search for “ZF transmission slipping when hot.”
- Abnormal vibration during shifting: A loose housing assembly creates play in the driveline, resulting in a distinct shudder during gear changes. This symptom is frequently searched as “ZF WG210 vibration fix.”
- Increased noise from the bell housing area: Without the correct CYLINDRICAL PIN securing the housing sections, metallic rattling occurs at idle.

Compatibility
This loose parts kit is primarily designed for the ZF WG 210 series, but it also fits select models in the WG180 and WG200 families due to shared housing architecture. Specifically, it is compatible with WG180, WG200, and WG210 transmissions built after 2005. The kit includes the necessary CAP SCREW and FIXING PLATE hardware to secure the SCREEN SHEET and SCREEN SHEET assemblies. Always verify your transmission serial number before ordering, as variations exist in the OIL FEED.HOUSG. configuration.
