ZF 2095.346.048 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.346.048 GEAR is a precision-machined helical gear designed for the countershaft assembly within ZF’s WG100, WG130, and WG131 heavy-duty transmissions. This OEM genuine component, identified by SKU 2095.346.048, directly transfers torque from the input shaft to the intermediate shaft, enabling smooth power flow during gear engagement. It sits in the lower gear train cluster and meshes with the corresponding output gear set. For optimal differential performance, this gear works in concert with the 5838109007: DIFFERENTIAL to manage load distribution across the axle.

Symptoms of Failure

When the 2095.346.048 GEAR wears out, operators often notice distinct operational issues. Look for these specific failure indicators:

• Whining or howling noise during acceleration: A high-pitched metallic sound from the transmission housing, particularly in 3rd and 4th gears, indicates tooth surface pitting or spalling.
• Gear slipping under load: The transmission may momentarily lose torque delivery when climbing grades or hauling heavy loads, caused by worn tooth profiles failing to maintain proper mesh.
• Metal particles in transmission oil: Fine metallic debris on the drain plug magnet or in the oil filter signals advanced gear wear, often accompanied by a burnt smell from degraded lubricant.
• Hard shifting or gear clash: Difficulty engaging gears or a grinding sensation during shifts points to damaged gear teeth that prevent smooth synchronization.

Technical Specifications

Compatibility

This gear is engineered specifically for ZF’s WG-series manual transmissions. It is a direct fit for the WG100, WG130, and WG131 models. It also serves as a replacement in the WG180 and WG200 variants when used in the countershaft position, though verification of tooth count and shaft spline is recommended. The gear interfaces with the 0750117075: TAPER ROLLER BEARING for shaft support and the 2095209019: DIFFERENTIAL for final drive integration. A 0631329086: SPRING PIN secures the gear to the shaft, preventing axial movement during operation.
