Overview
The ZF 4657.183.411 LOOSE PARTS set is a critical service kit designed for the WG210 series transmission. This genuine OEM assembly contains the specific fasteners, seals, and positioning components required to secure the main housing sections during a rebuild or overhaul. The SKU 4657.183.411 is installed directly within the transmission casing to ensure proper alignment and clamping force between the front and rear housing sections. Without this loose parts kit, the structural integrity of the gear train assembly is compromised, leading to misalignment under load.
Symptoms of Failure
When the ZF 4657.183.411 LOOSE PARTS kit wears out or is missing during reassembly, operators will notice distinct failure modes. Oil weeping from the main housing seam is the most common symptom, as the included seals lose their compression. Intermittent gear slipping under moderate torque occurs when the housing bolts loosen, allowing the shafts to shift out of parallel. Metallic grinding noises during gear engagement indicate that the loose parts have failed to maintain proper bearing preload. Finally, difficulty shifting into reverse or first gear often points to a misaligned housing section caused by degraded components in this kit.

Compatibility
This genuine ZF loose parts kit is engineered primarily for the WG210 transmission series. Based on the part type and housing interface, it is also compatible with the WG180, WG200, and WG211 models where the main housing architecture is shared. The 4657.183.411 kit works in conjunction with the 4657101082 TRANSMISSION HOUSING to form the outer casing. It also secures the 4657201166 HOUS.FRONT SECT and the 4657201170 HOUSING REAR PART to the main assembly. For complete rear closure, the 4657298102 HOUSING REAR SECTION is also fastened using this kit.
