ZF 0730.300.832 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.300.832 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG200 series transmissions. This critical shim element sits between the planetary gear set and the clutch housing assembly, maintaining exact axial clearance to ensure proper gear engagement and hydraulic pressure distribution. The SKU 0730.300.832 functions as a load-bearing separator that prevents metal-on-metal contact between rotating assemblies, directly influencing torque transfer efficiency. When installed correctly alongside a 4460165051: CONSOLE and 4460368311: CONSOLE, this spacer ring establishes the foundation for reliable power transmission in heavy-duty industrial applications.

Symptoms of Failure

• Transmission oil leaks around the bell housing – A worn spacer ring allows axial play that compromises seal integrity, causing fluid seepage at the joint between the gearbox and engine adapter.
• Gear slipping under load during uphill operation – Insufficient spacer thickness reduces clutch pack clamping force, leading to intermittent power loss when the transmission is under maximum torque demand.
• Metallic grinding noise during gear changes – Degraded spacer material permits gear clash as planetary components lose their precise alignment, producing a distinct scraping sound during shifts.
• Vibration in neutral at idle – Uneven wear on the spacer ring creates rotational imbalance that transmits through the driveline, felt as a low-frequency shudder when the transmission is disengaged.

Technical Specifications

Compatibility

This spacer ring is engineered for the ZF WG200 transmission series, including models WG180, WG200, and WG210. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. The part directly interfaces with the 0636011429: HEXAGON SCREW and 0730100365: WASHER during installation, forming a secure fastening system for the clutch drum assembly. Always verify your transmission serial number against ZF application charts before ordering.
