ZF 4661.202.007 CENTRAL SHAFT for WG94 | OEM Genuine Part

Overview

The ZF 4661.202.007 CENTRAL SHAFT is a critical rotating component engineered specifically for the WG 94 Series transmission family. This OEM genuine part serves as the primary torque-transfer element within the planetary gear set, ensuring precise alignment of gears and clutches during high-load operations. The SKU 4661.202.007 interfaces directly with the 4661101013: TRANSMISSION HOUSING and the 4661301022: HOUSING, forming the structural backbone of the gear train. Without this central shaft, the transmission cannot maintain synchronized power flow between input and output shafts.

Symptoms of Failure

• Erratic gear engagement or slipping: A worn central shaft causes misalignment of clutch packs, leading to delayed or incomplete gear shifts under load.
• Metallic grinding noise from the transmission housing: Bearing surface wear on the shaft produces a distinct grinding sound, especially during acceleration or deceleration.
• Oil leaks near the shaft seal area: Excessive radial play damages the seal contact surface, allowing transmission fluid to escape past the 0631306174: CYLINDRICAL PIN retention points.
• Vibration through the driveline: Unbalanced shaft rotation transfers harmonic vibrations to the vehicle chassis, worsening at higher RPM ranges.

Technical Specifications

Compatibility

This central shaft is designed for the ZF WG 94 Series, but it also fits select models in the WG180, WG200, and WG250 transmission families where the same planetary carrier geometry is used. Always verify the spline count and bearing journal dimensions against your existing shaft. The 0769123894: TYPE PLATE on your transmission housing provides the exact model designation for cross-referencing.
