ZF 0730.162.344 SPACER RING for WG200 | OEM Genuine Part

Overview

The ZF 0730.162.344 SPACER RING is a precision-machined component engineered specifically for the WG 200 Series transmission family. This OEM genuine part functions as a critical axial spacer within the planetary gearset assembly, maintaining exact clearance between rotating elements to prevent metal-on-metal contact under high-torque loads. The SKU 0730.162.344 ensures consistent clamping force when paired with the 4460165051 CONSOLE and the 4460368311 CONSOLE, both of which secure the spacer ring in its precise operating position. Without this ring, gear alignment tolerances degrade rapidly, leading to premature wear across the entire drivetrain assembly.

Symptoms of Failure

When the ZF 0730.162.344 SPACER RING wears beyond specification, operators typically notice these four distinct failure indicators:

• Low-frequency gear whine during acceleration — a direct result of increased axial play in the planetary carrier, often misdiagnosed as bearing noise.
• Intermittent oil seepage at the bell housing seam — caused by spacer ring deformation that shifts the 0636011429 HEXAGON SCREW torque distribution unevenly.
• Hard shifting between 2nd and 3rd gears — the spacer ring’s reduced thickness alters clutch pack clearances, delaying hydraulic engagement.
• Metallic debris in transmission fluid filter — worn spacer ring material contaminates the oil circuit, accelerating damage to the 0730100365 WASHER and adjacent sealing surfaces.

Technical Specifications

Compatibility

This OEM genuine spacer ring is engineered for the ZF WG 200 Series, including the WG180, WG200, and WG210 variants. It directly replaces the original factory spacer in planetary gearset positions where axial clearance must be held to ±0.05 mm. The part also fits select ZF Ecomat 5HP and 6HP models when used with the appropriate 4644305041 ADAPTER. For WG200 transmissions equipped with a 4460168651 INPUT FLANGE, verify that the spacer ring groove depth matches the flange shoulder height before installation.
