ZF 4661.272.001 COUPLING for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.272.001 COUPLING is a precision-engineered OEM genuine component designed specifically for the WG 90 and WG 94 series transmissions. This coupling serves as the critical mechanical link between the torque converter and the transmission input shaft, ensuring smooth power transfer and torsional vibration dampening. As part of the driveline assembly, the SKU 4661.272.001 interfaces directly with the 4661101001 TRANSMISSION HOUSING and the 4661301007 HOUSING to maintain proper alignment and load distribution. This genuine ZF part is manufactured to exacting tolerances, providing reliable performance in heavy-duty industrial applications where torque management is paramount.

Symptoms of Failure

• Torque converter shudder or vibration: When the 4661.272.001 coupling wears, operators often experience a noticeable shudder during acceleration or under load, particularly at low speeds. This is a common search query for “ZF WG90 coupling vibration issues.”
• Transmission fluid leaks near the bell housing: A worn coupling can compromise the seal interface, leading to oil seepage around the front of the transmission. This symptom is frequently searched as “ZF WG94 oil leak bell housing.”
• Delayed or harsh engagement: Worn splines or dampening elements within the coupling cause a delay in gear engagement or a jarring shift feel. Technicians often search for “ZF transmission coupling failure symptoms” to diagnose this issue.
• Metallic rattling noise at idle: Excessive play in the coupling produces a distinct rattling sound when the transmission is in neutral or park, a symptom commonly queried as “ZF WG90 rattling noise.”

Technical Specifications

Compatibility

This genuine ZF 4661.272.001 coupling is engineered for the WG 90 and WG 94 transmission series. Based on its design and spline configuration, it is also compatible with the WG 180, WG 200, and WG 210 models commonly found in industrial and off-highway equipment. The coupling works in conjunction with the 4661301093 TUBE for lubrication flow and is secured using the 0631306174 CYLINDRICAL PIN for precise alignment. Always verify your transmission model and serial number before ordering to ensure correct fitment.
