ZF 4651.364.038 PIN for WG100/WG201 | OEM Genuine Part

Overview

The ZF 4651.364.038 PIN is a precision-machined locating and alignment component engineered for the WG 100 and WG 201 series transmissions. This OEM genuine part serves as a critical positioning element within the transmission housing assembly, ensuring correct axial alignment of internal gear sets and shaft components during operation. The SKU 4651.364.038 is specifically designed to withstand high shear loads and vibration fatigue common in heavy-duty industrial applications. It interfaces directly with the TRANSMISSION HOUSING (4644101160) and the TRANSMISSION HOUSING (4644301323), providing a secure mounting point for subsequent assembly layers.

Symptoms of Failure

When the ZF 4651.364.038 PIN wears or becomes damaged, operators may notice several distinct failure indicators. Transmission housing misalignment is a primary symptom, often presenting as uneven gear contact patterns that generate excessive noise during load shifts. Oil seepage around the pin bore can occur if the pin loses its interference fit, allowing lubricant to bypass the O-RING (0634306198) seal. Intermittent gear slipping under torque is another common complaint, as the pin’s failure to maintain precise spacing allows shafts to drift out of tolerance. Finally, vibration at specific RPM ranges often indicates that the pin has fatigued, causing harmonic instability within the gear train.
