ZF 0730.260.647 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.260.647 SPACER RING is a precision-engineered OEM genuine component designed for the WG 200 Series transmission. This critical shim element sits between the planetary gear set and the clutch housing assembly, ensuring correct axial clearance and load distribution during high-torque operations. The SKU 0730.260.647 maintains exacting tolerances to prevent gear train misalignment and reduce vibration under heavy-duty cycles. Without this spacer ring, the transmission’s internal stack-up height becomes compromised, leading to premature wear on adjacent components.

Symptoms of Failure

• Oil leaks around the transmission housing: A worn or collapsed spacer ring allows the seal surfaces to shift, causing pressurized ATF to escape past the gaskets.
• Gear slipping under load: When the spacer ring loses its thickness, clutch pack clearance increases, resulting in delayed engagement and torque loss during acceleration.
• Abnormal whining or grinding noises: Insufficient axial preload from a degraded spacer ring permits gear teeth to contact unevenly, generating metallic sounds from the WG200’s planetary section.
• Erratic shift timing: The transmission control unit detects unexpected clutch fill times due to altered clearances, triggering fault codes and harsh shifts.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG200 series and its direct derivatives, including the WG180, WG200, and WG210 models. It also fits select ZF 4WG-200 and 5WG-200 off-highway transmissions used in wheel loaders, graders, and heavy-duty trucks. Always verify your transmission’s serial number against the OEM parts catalog before installation.

During replacement, technicians often pair this spacer ring with the 4460165051 CONSOLE and the 4460368311 CONSOLE to ensure proper alignment of the valve body assembly. The 0636011429 HEXAGON SCREW secures the spacer ring in position, while the 0730100365 WASHER distributes clamping force evenly across the mating surfaces.
