Overview
The ZF 4657.183.195 LOOSE PARTS kit is a critical service component engineered specifically for the WG 210 series transmission. This genuine OEM assembly contains the necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies within the gearbox. As part of the main case structure, this kit works in direct conjunction with the 4657101080: TRANSMISSION HOUSING to maintain precise alignment of rotating shafts and planetary gear sets. The SKU 4657.183.195 is often ordered during a full overhaul to replace all loose hardware that fatigues over extended service intervals.
Symptoms of Failure
- Transmission oil leaks at the housing joint: When the loose hardware in the 4657.183.195 kit fatigues, the clamping force between the 4657201167: HOUS.FRONT SECT and the main case diminishes, leading to external fluid seepage.
- Abnormal gear engagement noise (clunking): Worn or missing fasteners allow micro-movement of the 4657201171: HOUSING REAR PART, causing misalignment that produces metallic clatter during shifts.
- Intermittent loss of drive in forward gears: A compromised loose parts set can cause the 4657298103: HOUSING REAR SECTION to shift position, resulting in partial clutch pack disengagement.
- Vibration through the driveline at highway speeds: Degraded fasteners fail to maintain concentricity of the output shaft support structure, inducing harmonic vibration.

Compatibility
This genuine OEM loose parts kit is primarily validated for the ZF WG 210 transmission series. Based on the part’s structural role in securing the housing sections, it is also compatible with the WG 180 and WG 200 series when those units share the same rear housing architecture. The kit directly interfaces with the 4657101080: TRANSMISSION HOUSING and the 4657201167: HOUS.FRONT SECT. For complete rebuilds, always verify that the 4657201171: HOUSING REAR PART and 4657298103: HOUSING REAR SECTION are free from cracks before installing this kit.
