ZF 0730.260.646 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.260.646 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission. This critical shim sits between the planetary gear set and the clutch housing, maintaining exact axial clearance to ensure proper gear engagement and hydraulic pressure distribution. The SKU 0730.260.646 is manufactured to ZF’s original tolerances, providing a factory-spec fit that aftermarket alternatives cannot replicate. Without this spacer ring, the entire WG200 assembly risks misalignment under heavy torque loads.

Symptoms of Failure

When the ZF 0730.260.646 SPACER RING wears beyond specification, operators typically notice these failure indicators:

• Transmission oil leaks from the bell housing – A worn spacer ring allows the seal to shift, causing fluid seepage around the CONSOLE mounting area.
• Gear slipping under load – Insufficient axial clearance from a collapsed spacer ring reduces clutch pack clamping force, leading to power loss during acceleration.
• Metallic grinding noises during shifting – The spacer ring’s failure permits metal-on-metal contact between the gear set and the CONSOLE, producing audible wear debris.
• Erratic shift timing – Hydraulic pressure fluctuations caused by incorrect spacer ring thickness trigger delayed or harsh gear changes.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It is a direct replacement for units built between 2008 and 2023. The 0730.260.646 interfaces with the HEXAGON SCREW that secures the console assembly, and it must be paired with the correct WASHER to prevent fastener loosening. Always verify your transmission’s serial number against ZF’s parts catalog before ordering.
