ZF 4660.305.051 OUTPUT SHAFT for WG92 | OEM Genuine Part

Overview

The ZF 4660.305.051 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 92 Series transmission family. This OEM genuine part transfers rotational torque from the planetary gear set to the vehicle’s drive shaft, ensuring smooth power delivery under heavy-duty loads. Machined from high-strength alloy steel, the output shaft interfaces directly with the TRANSMISSION HOUSING and the HOUSING II to maintain precise alignment and bearing support. The SKU 4660.305.051 is factory-balanced to minimize vibration and extends service life in demanding industrial applications.

Symptoms of Failure

• Oil leaks near the rear seal area: A worn output shaft can damage the sealing surface, causing transmission fluid to weep or drip. This often appears as a wet patch beneath the vehicle.
• Gear slipping or delayed engagement: When the splines on the output shaft wear, torque transfer becomes inconsistent, leading to hesitation or slipping during acceleration.
• Abnormal driveline vibration: A bent or fatigued shaft creates rhythmic shaking at highway speeds, often mistaken for wheel imbalance.
• Metallic grinding noise from the transmission housing: Bearing failure caused by shaft runout produces a distinct grinding sound, especially in neutral or low gears.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 92 Series, which includes models such as WG92, WG120, WG150, WG180, and WG200. It is also compatible with select off-highway and marine transmissions that share the same spline interface and bearing arrangement. Always verify the TYPE PLATE on your unit to confirm model and serial number before installation. The shaft is secured using a CYLINDRICAL PIN to prevent rotational slippage.
