Overview
The ZF 4657.362.007 CENTERING FLANGE is a precision-machined component designed for the WG 210 Series transmission. This OEM genuine part ensures exact alignment between the transmission output shaft and the driveline, minimizing vibration and preventing premature wear on seals and bearings. Located at the rear of the gearbox, the centering flange (SKU: 4657.362.007) acts as a critical interface, maintaining concentricity during torque transfer. For optimal assembly integrity, this flange works in concert with the 4657101042: TRANSMISSION HOUSING and the 4657201028: HOUS.FRONT SECT, which together form the structural backbone of the transmission casing.
Symptoms of Failure
When the ZF 4657.362.007 centering flange deteriorates, operators may notice distinct operational issues. Oil seepage around the output shaft seal is a common early indicator, as misalignment compromises the seal’s contact surface. Persistent driveline vibration during acceleration often follows, caused by the flange losing its precise centering capability. Additionally, intermittent gear engagement difficulty can occur, particularly in lower ratios, due to slight axial play. In severe cases, metallic debris in the transmission fluid signals that the flange has worn against the 4657201013: HOUSING REAR PART, requiring immediate replacement to avoid cascading damage.

Compatibility
This centering flange is engineered for the ZF WG 210 Series, but its design principles extend to several related transmission models. It is directly compatible with the WG180, WG200, and WG210 series, all of which share the same output shaft geometry and housing interface. The flange also fits select variants of the WG150 and WG250 series, provided the rear housing section matches the bolt pattern. For precise fitment, always verify the housing part numbers, particularly the 0631306792: CYLINDRICAL PIN, which aligns the flange during installation and prevents rotation under load.
