ZF 0730.300.830 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.300.830 SPACER RING is a precision-engineered OEM component designed for the WG 200 Series transmission family. This critical shim maintains exact axial clearance between rotating assemblies within the gear train, ensuring proper load distribution and alignment. The SKU 0730.300.830 is factory-specified for the WG200, WG180, and related heavy-duty off-highway transmissions. When installed alongside the 4460165051: CONSOLE and 4460368311: CONSOLE, this spacer ring prevents metal-to-metal contact between planetary gear sets and the housing.

Symptoms of Failure

• Oil leaks at the bell housing — A worn spacer ring allows axial play, breaking the seal between the 0636011429: HEXAGON SCREW and the housing, leading to external fluid seepage.
• Gear slipping under load — Excessive clearance from a collapsed spacer ring reduces clutch pack clamping force, causing intermittent power loss during torque converter lockup.
• Metallic debris in transmission fluid — Abrasion between the spacer ring and the 0730100365: WASHER generates fine steel particles that contaminate the hydraulic circuit.
• Vibration during shifting — Loss of axial preload allows the planetary carrier to wobble, producing low-frequency rumble in 2nd and 3rd gears.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG series powershift transmissions, specifically the WG180, WG200, and WG211 models used in construction equipment, mining trucks, and agricultural machinery. It fits both standard and reinforced housing variants. For proper installation, always pair with the 4644105418: DISCONNECTION and 4644305041: ADAPTER to ensure correct stack height. The ring also interfaces with the 4460068159: AXLE DRIVE and 4460168651: INPUT FLANGE in the torque path.
