ZF 0730.063.100 SPACER RING for WG200/WG201 | OEM Genuine Part

Overview

The ZF 0730.063.100 SPACER RING is a precision-machined component engineered for the WG200 and WG201 series transmissions. This OEM genuine part functions as a critical axial spacer, maintaining exact clearance between the planetary gear sets and the transmission housing. By ensuring proper load distribution and component alignment, the spacer ring prevents metal-on-metal contact that would otherwise lead to premature wear. The SKU 0730.063.100 is specifically designed to withstand high torque loads and thermal expansion within the transmission assembly. When installed correctly, this ring works in concert with the 4644101216: TRANSMISSION HOUSING and the 4644301223: TRANSMISSION HOUSING to create a stable, sealed environment for rotating components.

Symptoms of Failure

When the ZF 0730.063.100 SPACER RING wears out, operators may notice several distinct failure indicators. Oil leaks around the transmission housing interface often appear first, as the ring loses its sealing capability. Gear slipping under load becomes common when axial play exceeds factory tolerances, particularly during uphill climbs or heavy towing. Metallic grinding noises from the transmission indicate the ring has thinned enough to allow gear contact with the housing. Delayed engagement when shifting from neutral to drive can also signal spacer ring degradation, as internal clearances shift beyond acceptable limits.

Technical Specifications

Compatibility

This spacer ring is primarily designed for ZF WG200 and WG201 series transmissions. It is also compatible with the WG180 series in certain configurations, though verification of axial clearance is recommended. The part interfaces directly with the 0730365067: TYPE PLATE for identification purposes and requires the 0631311009: GROOVED STUD for proper retention during assembly. Models including WG200, WG201, and select WG180 variants benefit from this component’s precise dimensional tolerances.
