ZF 4651.351.041 SPUR GEAR for WG100 | OEM Genuine Part

Overview

This ZF 4651.351.041 SPUR GEAR is a critical power transmission component designed for the WG 100 series transmissions. It functions as a precision-machined gear that transfers torque between parallel shafts within the gear train, ensuring smooth and efficient power flow under heavy-duty industrial loads. As an OEM genuine part, the SKU 4651.351.041 is engineered to exact ZF tolerances, providing reliable meshing and minimal backlash. This spur gear sits within the main gear cluster, often adjacent to the 4651101006: TRANSMISSION HOUSING, which encloses the entire assembly and maintains proper gear alignment.

Symptoms of Failure

When the ZF 4651.351.041 spur gear begins to wear, operators may notice several distinct failure indicators. Whining or grinding noise during gear engagement is a common early sign, often caused by pitting or spalling on the gear teeth. Vibration in the driveline at specific RPM ranges indicates uneven tooth wear or chipping. Metallic debris in the transmission oil filter or sump is a critical symptom of advanced gear degradation. Additionally, intermittent power loss or gear slipping under load can occur when the gear profile is no longer able to maintain proper contact with its mating pinion. These issues often require inspection of the 4651301034: HOUSING for any impact damage that may have contributed to gear misalignment.

Technical Specifications

Compatibility

This spur gear is primarily designed for the ZF WG 100 series transmission family. Based on its module and tooth profile, it is also compatible with the following ZF models: WG 120, WG 150, WG 180, and WG 200 series transmissions used in construction, agricultural, and material handling equipment. Always verify the gear count and shaft center distance before installation. The gear interfaces directly with the 4651301013: HOUSING and requires a proper seal using the 0634303928: O-RING to prevent oil ingress into the bearing cavities.
