ZF 0730.308.419 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.308.419 SPACER RING is a precision-engineered OEM genuine component designed for the WG 200 Series transmission family. This critical shim component 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 0730.308.419 serves as a load-bearing spacer that prevents metal-to-metal contact between rotating assemblies, directly influencing the transmission’s torque capacity and shift quality. Without this spacer ring, the entire gear train loses its dimensional integrity, leading to premature wear of adjacent components.

Symptoms of Failure

• Delayed gear engagement or slipping in forward gears: When the spacer ring wears beyond tolerance, the clutch pack clearance increases, causing hydraulic pressure loss and sluggish shifting.
• Metallic grinding noise during acceleration: A worn 0730.308.419 allows the planetary carrier to contact the housing, producing a distinct grinding sound under load.
• Transmission fluid contamination with bronze particles: As the spacer ring degrades, microscopic metal shavings enter the oil circuit, often visible during routine fluid changes.
• Intermittent loss of drive in reverse: Insufficient spacer height reduces clamping force on the reverse clutch pack, leading to sporadic power delivery.

Technical Specifications

Compatibility

This spacer ring is specifically engineered for the ZF WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. The part is not interchangeable with WG150 or WG250 series due to different shaft diameters. For proper installation, always pair this spacer with the corresponding 4460165051: CONSOLE and 4460368311: CONSOLE to maintain correct housing alignment. Secure the assembly using the 0636011429: HEXAGON SCREW and 0730100365: WASHER to achieve the specified torque of 45 Nm.
