Overview
The ZF 4657.183.268 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 series transmission. This OEM genuine part set contains the necessary fasteners, seals, and positioning components required to secure and align the main structural elements of the gearbox. The SKU 4657.183.268 is typically employed during a full rebuild or when replacing major housing sections, ensuring that the TRANSMISSION HOUSING maintains proper clamping force and oil-tight integrity. Without this specific loose parts kit, reassembly of the WG210 can lead to misalignment and premature wear of internal rotating assemblies.
Symptoms of Failure
When the components within the ZF 4657.183.268 LOOSE PARTS set degrade or are omitted during service, operators often report external oil seepage at the main housing joints, a classic sign of compromised gasket or fastener tension. Another frequent complaint is abnormal gear rattle or vibration during load shifts, indicating that the HOUS.FRONT SECT is not properly indexed. Technicians also encounter difficulty engaging reverse gear due to slight axial movement of the HOUSING REAR PART. Finally, erratic clutch pack pressure can occur if the loose parts fail to secure the HOUSING REAR SECTION, leading to slipping under heavy torque.

Compatibility
This genuine ZF loose parts kit is engineered for the WG 210 series, but its fastening geometry also suits the WG 180 and WG 200 variants due to shared bell-housing patterns. It is compatible with WG 211 and WG 212 models that utilize the same rear section interface. Always verify the serial number of your transmission before ordering, as the 4657.183.268 kit is not intended for the older WG 150 series.
