ZF 0730.308.418 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.308.418 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG200 series transmissions. This critical shim component sits between the planetary gear set and the housing, ensuring correct axial clearance and load distribution during operation. The SKU 0730.308.418 is manufactured to ZF’s exacting tolerances, providing the necessary spacing to prevent metal-on-metal contact within the rotating assembly. Without this spacer ring, the transmission’s internal clearances would fall outside factory specifications, leading to premature wear of adjacent components such as the 4460165051 CONSOLE and 4460368311 CONSOLE.

Symptoms of Failure

When the ZF 0730.308.418 SPACER RING wears out or becomes damaged, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Transmission oil leaks at the housing seam – A worn spacer ring allows the seal surfaces to shift, causing fluid to escape past the gasket.
• Gear slipping under load – Incorrect spacing reduces clutch pack engagement pressure, resulting in hesitation or slipping during acceleration.
• Abnormal whining or grinding noise from the gear train – Metal-to-metal contact from insufficient clearance produces a distinct high-pitched sound during operation.
• Increased vibration in the driveline – Misalignment caused by a collapsed spacer ring transmits excessive vibration through the 0636011429 HEXAGON SCREW and 0730100365 WASHER assemblies.

Technical Specifications

Compatibility

This OEM genuine spacer ring is primarily designed for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It also fits select variants of the ZF Ecomat 4HP and 5HP series where the planetary carrier spacing matches the 68 mm inner diameter. Always verify your transmission model number before ordering. The spacer ring works in conjunction with the 4644105418 DISCONNECTION unit and 4644305041 ADAPTER to maintain proper driveline geometry.
