ZF 4661.102.016 INPUT for WG94 | OEM Genuine Part

Overview

The ZF 4661.102.016 INPUT for WG94 is a critical OEM genuine component engineered to manage torque transfer from the engine to the planetary gearset within ZF’s WG 94 Series transmissions. This input shaft assembly, referenced by SKU 4661.102.016, sits directly behind the torque converter and interfaces with the 4661101024: TRANSMISSION HOUSING to ensure precise alignment and load distribution. Designed for heavy-duty industrial applications, this part maintains the structural integrity of the drivetrain by absorbing rotational stress and minimizing vibration during high-torque operations.

Symptoms of Failure

• Oil leaks near the bell housing: Worn splines or seal surfaces on the 4661.102.016 can cause transmission fluid to escape, often mistaken for a failing gasket.
• Gear slipping under load: A degraded input shaft loses its ability to maintain positive engagement with the clutch pack, leading to intermittent power loss during acceleration.
• Metallic grinding noises: Excessive wear on the shaft’s bearing journals produces a distinct grinding sound, particularly when shifting between forward and reverse gears.
• Delayed engagement: If the input shaft’s pilot bearing surface is scored, operators may experience a noticeable lag when selecting a gear from neutral.

Technical Specifications

Compatibility

This input shaft is specifically designed for the WG 94 Series transmission family, which includes models such as the WG180, WG200, and WG240. It is also compatible with certain variants of the ZF WG150 and WG160 when used in conjunction with the 4661301054: HOUSING II. For proper installation, ensure the 0631306174: CYLINDRICAL PIN is correctly seated to prevent rotational misalignment. Always verify the 0769123894: TYPE PLATE on your transmission to confirm exact model compatibility before ordering.
