Overview
The ZF 4657.183.244 LOOSE PARTS kit is a critical service component designed for the WG210 series transmission. This assembly contains the necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies within the gearbox housing. Specifically, the 4657.183.244 set interfaces directly with the main casing and the front section to ensure precise alignment of rotating shafts. As an OEM genuine part, it guarantees factory tolerances for rebuilds and overhauls. When replacing major structural components such as the 4657101079: TRANSMISSION HOUSING, this loose parts kit is mandatory to restore clamping force and prevent fluid migration between chambers.
Symptoms of Failure
- Intermittent gear slippage under load: Worn or missing loose parts can cause the housing sections to shift, leading to a loss of hydraulic pressure on clutch packs.
- External oil seepage at housing joints: Degraded sealing elements within the 4657.183.244 kit allow transmission fluid to weep between the 4657201166: HOUS.FRONT SECT and the main body.
- Abnormal vibration during gear changes: Loose fasteners in this kit permit micro-movement of the 4657201169: HOUSING REAR PART, creating driveline shudder.
- Delayed engagement from park to drive: Internal misalignment caused by degraded loose parts affects valve body alignment, delaying hydraulic response.

Compatibility
This loose parts kit is primarily engineered for the WG 210 Series transmission family. Based on its structural role, it is also compatible with the WG180 and WG200 models where the 4657298104: HOUSING REAR SECTION is used. The kit supports both on-highway and off-highway ZF applications, including municipal trucks, refuse vehicles, and construction equipment. Always verify the housing casting numbers before ordering, as variations exist between early and late production runs of the WG200 series.
