ZF 0730.260.644 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.260.644 SPACER RING is a precision-engineered component designed for the WG200 series transmission. This OEM genuine part functions as a critical axial spacer, maintaining exact clearances between rotating assemblies within the gear train. Positioned between the planetary gear sets and the clutch housing, the spacer ring ensures proper load distribution and prevents metal-on-metal contact. The SKU 0730.260.644 is manufactured to ZF’s original specifications, guaranteeing dimensional accuracy and material hardness for long service life in heavy-duty applications.

Symptoms of Failure

When the ZF 0730.260.644 spacer ring wears beyond tolerance, operators may notice specific transmission issues. Oil leaks around the bell housing often develop as the ring loses its sealing interface. Gear slipping under load becomes apparent, particularly during upshifts, due to altered clutch pack clearances. Unusual metallic grinding noises from the transmission sump indicate the ring has thinned, allowing gear clash. Delayed engagement when shifting from neutral to drive is another common symptom, as the spacer no longer maintains proper hydraulic pressure gaps.

Technical Specifications

Compatibility

This spacer ring is primarily engineered for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. The part fits both on-highway truck applications and off-highway construction equipment using these ZF gearboxes. Always verify your transmission model number before installation.
