ZF 0730.300.828 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.300.828 SPACER RING is a precision-engineered component designed for the WG 200 Series transmission family. This OEM genuine part functions as a critical axial spacer, maintaining exact clearance between rotating assemblies within the gear train. Installed on the main shaft or planetary carrier, the spacer ring ensures proper load distribution and prevents metal-to-metal contact under high torque conditions. The SKU 0730.300.828 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification. When paired with a CONSOLE (4460165051) or a CONSOLE (4460368311), this spacer ring completes the bearing preload assembly, reducing vibration and extending service life.

Symptoms of Failure

When the ZF 0730.300.828 SPACER RING wears or deforms, operators may notice these specific failure indicators:

• Oil leaks from the bell housing area — A worn spacer ring can shift, breaking the seal between the pump housing and the main case, leading to fluid seepage.
• Gear slipping under load — Loss of axial clearance causes clutch pack clearance to open, resulting in delayed engagement or slipping during acceleration.
• Abnormal whining or grinding noise — Metal-on-metal contact from a collapsed spacer ring produces a distinct high-pitched whine, especially in lower gears.
• Hard shifting or erratic shift timing — Incorrect spacer height alters hydraulic pressure balance, causing harsh or delayed shifts in the WG200 transmission.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG 200 Series transmissions, including the WG180, WG200, and WG210 models. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. For proper installation, always verify the axial stack-up using a new HEXAGON SCREW (0636011429) and a WASHER (0730100365) to secure the assembly to OEM torque specifications. The spacer ring is not interchangeable with earlier ZF 4WG models without checking the shaft diameter.
