ZF 0730.300.831 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.300.831 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission. This critical shim component sits between the planetary gear set and the clutch housing assembly, maintaining exact axial clearance to ensure proper gear engagement and hydraulic pressure distribution. The SKU 0730.300.831 is manufactured to ZF’s original tolerances, preventing metal-on-metal contact that can lead to premature wear. When installed alongside the 4460165051 CONSOLE and 4460368311 CONSOLE, this spacer ring forms the foundation of the transmission’s rotating assembly stability.

Symptoms of Failure

When the 0730.300.831 SPACER RING wears beyond specification, operators will notice distinct performance degradation. Oil leaks around the bell housing often appear first, as the compromised ring disrupts the seal between the pump and converter. Gear slipping during load shifts becomes common, particularly in 3rd and 4th gears, due to insufficient clutch pack clearance. Abnormal whining or grinding noises from the transmission center section indicate the spacer has thinned, allowing gear teeth to contact improperly. In severe cases, delayed engagement when shifting from Neutral to Drive signals that the spacer ring has failed to maintain hydraulic pressure integrity.

Technical Specifications

Compatibility

This ZF 0730.300.831 SPACER RING is engineered for the WG 200 Series transmission family, including models WG180, WG200, and WG210. It is also compatible with select Ecomat 2 and Ecomat 4 variants that share the same planetary carrier architecture. Always verify the spacer ring thickness against your transmission’s service manual, as wear in the 0636011429 HEXAGON SCREW and 0730100365 WASHER can alter the required clearance. For complete assembly, this part works with the 4644105418 DISCONNECTION and 4644305041 ADAPTER to ensure proper torque transfer.
