Overview
The ZF 0730.260.652 SPACER RING is a precision-engineered OEM genuine component designed for the WG 200 Series transmission family. This spacer ring functions as a critical axial positioning element within the planetary gearset assembly, ensuring correct clearance between rotating and stationary components. The SKU 0730.260.652 is manufactured to ZF’s exacting tolerances to maintain optimal gear mesh alignment and prevent metal-to-metal contact under high torque loads. When installed alongside the 4460165051 CONSOLE and 4460368311 CONSOLE, this spacer ring helps secure the entire clutch drum assembly, reducing vibration and extending service intervals.
Symptoms of Failure
When the ZF 0730.260.652 spacer ring wears beyond specification, operators typically notice these failure indicators:
- Oil leaks near the transmission housing – A worn spacer ring allows pressurized fluid to bypass the sealing surfaces, often visible as drips around the bell housing or output flange area.
- Gear slipping under load – Loss of axial preload causes clutch packs to disengage intermittently, resulting in hesitation or RPM flare during acceleration.
- Abnormal metallic grinding noises – Insufficient clearance between the spacer ring and adjacent gears produces a high-pitched whine or grinding sound, especially during gear changes.
- Increased transmission operating temperature – Friction from misaligned components generates excess heat, which may trigger warning lights or reduce fluid life.

Compatibility
This spacer ring is engineered for the ZF WG 200 Series, including the WG180, WG200, and WG210 models. It is also compatible with certain ZF Ecomat 4HP and 5HP transmissions that share the same planetary carrier architecture. For proper installation, always pair the 0730.260.652 with the 0636011429 HEXAGON SCREW and 0730100365 WASHER to achieve correct torque specifications. Verify your transmission serial number against ZF’s technical documentation before ordering.
