ZF 0730.260.645 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.260.645 SPACER RING is a precision-engineered component designed for the WG 200 Series transmission family. This OEM genuine part serves as a critical axial positioning element within the planetary gearset assembly, ensuring correct clearance between rotating and stationary components. The spacer ring (SKU: 0730.260.645) maintains proper gear mesh alignment and prevents metal-on-metal contact under high-torque conditions. It is installed directly on the output shaft, adjacent to the 4460165051 CONSOLE and the 4460368311 CONSOLE, which together form the structural support bracket for the transmission housing.

Symptoms of Failure

• Transmission oil seepage at the output shaft seal: A worn spacer ring allows axial play, compromising the seal lip contact and causing gradual fluid loss. This is a common long-tail search query for “ZF WG200 oil leak output shaft.”
• Intermittent gear slipping under load: When the spacer ring loses its precise thickness, gear engagement depth decreases, leading to torque loss during acceleration—often searched as “WG200 slipping in forward gears.”
• Metallic grinding noise during deceleration: Excessive clearance from a collapsed spacer ring permits gear clash, producing a distinct grinding sound. Technicians frequently search for “ZF transmission grinding noise after rebuild.”
• Vibration in the driveline at highway speeds: Misalignment caused by a degraded spacer ring induces harmonic vibrations, a symptom often queried as “WG200 vibration at 50 mph.”

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG 200 Series, including the WG180, WG200, and WG210 models. It is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the same output shaft geometry. The part interfaces directly with the 0636011429 HEXAGON SCREW and the 0730100365 WASHER during installation, ensuring secure clamping of the console assembly. Always verify your transmission serial number against ZF’s parts catalog before ordering.
