ZF 4651.352.002 SPUR GEAR for WG100 | OEM Genuine Part

Overview

The ZF 4651.352.002 SPUR GEAR is a critical power transmission component engineered specifically for the WG 100 Series transmission family. This OEM genuine part, identified by SKU 4651.352.002, sits within the intermediate shaft assembly, where it precisely meshes with adjacent gears to transfer torque from the input shaft to the output shaft. By maintaining exact tooth geometry and surface hardness, this spur gear ensures smooth, vibration-free operation under heavy load conditions. It is typically housed within the 4651101007: TRANSMISSION HOUSING and works in conjunction with the 4651301029: HOUSING to maintain proper shaft alignment and lubrication flow.

Symptoms of Failure

When the ZF 4651.352.002 SPUR GEAR begins to wear, operators may notice several distinct failure indicators. Whining or howling noise during acceleration is a common early sign, often caused by pitting or spalling on the gear tooth flanks. Intermittent gear slipping under load occurs when tooth profiles become worn, reducing the contact ratio between meshing gears. Metallic debris in the transmission oil filter is a critical symptom, indicating advanced wear that can damage the 0634303928: O-RING seals and the 4651301024: HOUSING surfaces. Vibration through the gearshift lever at specific RPM ranges often signals uneven tooth wear or a bent gear shaft.

Technical Specifications

Compatibility

This spur gear is primarily designed for the ZF WG 100 Series transmission, which includes models such as WG100, WG120, and WG150. Based on its tooth geometry and shaft interface, it may also be compatible with the ZF WG 180 and WG 200 series when used in specific gear positions. Always verify the tooth count and bore diameter against your transmission’s parts manual. The gear interfaces directly with the 4651101007: TRANSMISSION HOUSING and the 4651301029: HOUSING to ensure correct axial positioning.
