ZF 0730.300.826 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.300.826 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission. This critical shim maintains exact axial clearance between rotating assemblies, ensuring proper load distribution and alignment within the gear train. Installed directly on the output shaft assembly, the SKU 0730.300.826 prevents metal-to-metal contact between adjacent components, preserving the integrity of the planetary gear set. Without this spacer ring, the transmission cannot maintain the tight tolerances required for reliable power transfer under heavy industrial loads.

Symptoms of Failure

When the 0730.300.826 SPACER RING wears or becomes damaged, operators may notice these specific failure indicators:

• Oil leaks near the output shaft housing – A worn spacer ring allows axial play, breaking the seal between the shaft and the 4460165051: CONSOLE assembly, leading to fluid seepage.
• Gear slipping under load – Loss of proper spacing causes misalignment in the planetary gears, resulting in intermittent power loss during acceleration or climbing.
• Metallic grinding noise from the transmission – As the spacer ring thins, hardened steel components contact each other, producing a distinct high-pitched whine or grinding sound during operation.
• Vibration in the driveline – Excessive axial movement from a collapsed spacer ring creates harmonic vibrations felt through the chassis, especially at highway speeds.

Technical Specifications

Compatibility

This OEM genuine spacer ring is engineered for the ZF WG 200 Series transmissions, including models WG180, WG200, and WG211. It is also compatible with select WG 150 variants that share the same output shaft diameter. The 0730.300.826 is frequently replaced alongside the 4460368311: CONSOLE and the 0636011429: HEXAGON SCREW during a full output shaft rebuild. Always verify fitment by checking the existing spacer ring thickness against your transmission’s service manual.

During installation, the 0730100365: WASHER must be positioned correctly to prevent galling. For complete assembly integrity, inspect the mating surfaces of the CONSOLE and HEXAGON SCREW for wear before torquing to factory specifications.
