ZF 4660.351.033 SUPPORTING RING for WG200/WG92 | OEM Genuine Part

Overview

The ZF 4660.351.033 SUPPORTING RING is a precision-engineered component designed for the WG200, WG92, and WG98 series transmissions. This OEM genuine part functions as a critical load-bearing element within the planetary gearset assembly, ensuring proper axial alignment and reducing vibration during torque transfer. The SKU 4660.351.033 sits between the 4660198001 PERIPHERALS and the main shaft, providing a hardened contact surface that prevents metal-to-metal wear. Its primary role is to maintain consistent spacing between rotating elements, directly influencing shift quality and overall transmission longevity.

Symptoms of Failure

• Oil leaks near the output flange — A worn supporting ring allows the seal to shift, causing ATF to weep from the rear housing. This is a common long-tail search query for “ZF WG200 oil leak output flange”.
• Gear slipping under load — When the ring loses its dimensional integrity, the planetary carrier can drift, leading to intermittent engagement loss during acceleration.
• Abnormal whining noise in neutral — A degraded supporting ring permits axial play, generating a high-pitched whine that intensifies with RPM, often searched as “ZF transmission whining noise neutral”.
• Hard shifting between ranges — Misalignment caused by ring wear forces the 0501209818 RANGE SELECTOR to work harder, resulting in delayed or harsh gear changes.

Technical Specifications

Compatibility

This supporting ring is engineered for ZF’s WG series powershift transmissions. It is directly compatible with the WG180, WG200, WG92, and WG98 models. The part also fits select variants of the WG150 series when used with the 4660101011 TRANSMISSION HOUSING and the 4660301018 HOUSING. Always verify your transmission’s serial number before installation, as minor design changes occurred after 2015 for the WG200 series.
