ZF 0730.063.231 RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.063.231 RING is a precision-engineered internal component specifically designed for the WG200 series of heavy-duty transmissions. This OEM genuine part functions as a critical sealing and spacing element within the planetary gearset assembly, ensuring correct axial clearance and preventing fluid bypass between rotating and stationary components. The SKU 0730.063.231 is manufactured to ZF’s exacting tolerances, making it essential for maintaining hydraulic pressure integrity and gear alignment in commercial vehicle drivelines. When installed alongside the 4644105414 DISCONNECTION mechanism, this ring helps synchronize clutch pack engagement for smoother shifting under load.

Symptoms of Failure

• Transmission fluid leaks around the output shaft housing – A worn 0730.063.231 ring allows pressurized oil to escape, often visible as drips near the 4644303409 OUTPUT FLANGE.
• Intermittent gear slipping during uphill hauling – Loss of sealing force reduces clutch pack clamping pressure, causing momentary power loss under torque.
• Metallic debris in the transmission oil pan – Abrasion of the ring surface generates fine steel particles, which can contaminate the 4644101222 TRANSMISSION HOUSING interior.
• Delayed engagement when shifting from neutral to drive – Reduced axial preload from a fatigued ring slows hydraulic response times.

Technical Specifications

Compatibility

This ring is engineered for the ZF WG200 series, including WG200, WG180, and WG150 variants used in municipal buses, fire trucks, and off-highway equipment. It also fits select ZF Ecolife models with the same planetary carrier design. Always verify fitment by cross-referencing the 0636021083 HEXAGON SCREW torque specifications in your service manual before installation.
