ZF 4950.102.002 INPUT for WG92/WG98 | OEM Genuine Part

Overview

The ZF 4950.102.002 INPUT for WG92/WG98 is a critical power transfer component situated at the front of the transmission assembly. This OEM genuine part, identified by SKU 4950.102.002, serves as the primary interface between the engine output and the transmission’s internal gear train. Engineered specifically for the WG 92 and WG 98 series, it ensures precise torque delivery and rotational alignment. When installed alongside the 4950101004: HOUSING and the 4950301018: HOUSING I, this input component forms a sealed, high-tolerance assembly that withstands heavy-duty industrial loads.

Symptoms of Failure

• Oil leaks near the front bell housing: A worn 4950.102.002 input often compromises the seal interface, leading to visible fluid seepage around the input shaft area. This is a common long-tail search query for “ZF WG92 input shaft oil leak.”
• Gear slipping under load: When the input splines or bearing surfaces degrade, the transmission may hesitate or slip during acceleration, particularly in higher gears. Technicians searching for “WG98 gear slipping input shaft” will find this relevant.
• Abnormal vibration or whining noise: Excessive wear on the input component causes misalignment, producing a distinct whining sound that intensifies with engine RPM. This symptom often prompts searches like “ZF transmission whining noise input bearing.”
• Difficult shifting or grinding: A failing input can prevent smooth engagement of forward and reverse gears, resulting in a grinding sensation during gear changes.

Technical Specifications

Compatibility

This genuine ZF input component is engineered for the WG 92 and WG 98 transmission series. It is directly compatible with models including the WG180, WG200, and WG210. The part also integrates seamlessly with the 4660101023: TRANSMISSION HOUSING to ensure proper alignment and sealing. For optimal performance, always pair this input with the correct shaft seal and housing components from the same assembly group.
