ZF 0730.260.648 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.260.648 SPACER RING is a precision-engineered OEM genuine component designed for the WG 200 Series transmissions. This critical spacer ring maintains exact axial clearance between rotating assemblies within the gear train, ensuring proper load distribution and alignment. The SKU 0730.260.648 is factory-specified for the WG200 planetary gear sets, where it sits between the sun gear and the carrier assembly. Without this spacer, internal components would experience metal-on-metal contact, leading to premature wear. When servicing the WG200, always pair this ring with a new 4460165051: CONSOLE and 4460368311: CONSOLE to ensure proper housing alignment.

Symptoms of Failure

When the 0730.260.648 SPACER RING wears or deforms, operators typically notice these specific failure indicators:

• Oil leaks at the transmission housing seam – A worn spacer ring allows axial movement, breaking the seal between the housing and the 0636011429: HEXAGON SCREW mounting points, causing fluid seepage.
• Gear slipping under load – Loss of spacer thickness reduces preload on the clutch packs, leading to intermittent power loss during acceleration.
• Metallic grinding noise from the WG200 – When the spacer collapses, planetary gears contact the 0730100365: WASHER surfaces, producing a distinct grinding sound during shifting.
• Vibration in neutral or drive – Uneven spacer wear causes rotational imbalance, felt as low-frequency vibration through the chassis.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with certain ZF 4WG-200 and 5WG-200 variants used in construction and agricultural machinery. Always verify the part number against your transmission’s serial plate. For complete rebuilds, consider the 4644105418: DISCONNECTION kit and 4644305041: ADAPTER to ensure all mating surfaces are properly sealed.
