Overview
The ZF 0730.260.650 SPACER RING is a precision-engineered component designed for the WG200 series transmission. This OEM genuine part serves as a critical axial spacer within the planetary gearset assembly, ensuring correct end-play and load distribution between rotating elements. The SKU 0730.260.650 is manufactured to ZF’s exacting tolerances, providing a hardened steel interface that maintains proper alignment of the clutch pack and sun gear shaft. Without this spacer ring, the transmission’s internal clearances would fall outside specification, leading to premature wear of adjacent components such as the 4460165051: CONSOLE and the 4460368311: CONSOLE.
Symptoms of Failure
When the 0730.260.650 spacer ring wears beyond its service limit, operators will notice distinct performance degradation. Oil leaks from the transmission housing bell housing area occur as the spacer loses its sealing surface contact. Gear slipping under moderate to heavy load becomes apparent, particularly during 2nd-to-3rd gear upshifts, due to altered clutch pack clearance. Abnormal metallic grinding noises during deceleration indicate the spacer ring has fractured or deformed. Erratic shift timing and harsh engagement are also common, as the valve body compensates for the changed axial play. These failure symptoms often require immediate replacement to prevent damage to the 0636011429: HEXAGON SCREW and 0730100365: WASHER that secure the console assembly.

Compatibility
This spacer ring is engineered for the ZF WG200 series transmissions, including the WG180, WG200, and WG210 variants. It is also compatible with certain ZF Ecomat 4HP and 5HP models that share the same planetary carrier architecture. The part directly interfaces with the 4460165051: CONSOLE and 4460368311: CONSOLE in the clutch housing. Always verify your transmission serial number against ZF’s parts catalog before installation, as minor revisions exist between early and late production units.
