ZF 2095.303.034 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.034 GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the countershaft assembly, where it meshes directly with the output shaft to modulate torque distribution during gear changes. As a precision-machined helical gear, it ensures smooth engagement and minimal backlash under heavy loads. The SKU 2095.303.034 is manufactured to ZF’s original tolerances, guaranteeing a direct fit and long service life when replacing worn components in these heavy-duty transmissions.

Symptoms of Failure

• Whining or grinding noise during acceleration: A worn 2095.303.034 gear produces a distinct high-pitched whine or metallic grinding sound, particularly when the transmission is under load in second or third gear.
• Intermittent gear slippage under load: As the gear teeth wear unevenly, the transmission may momentarily lose power delivery, causing the vehicle to hesitate or “jump” out of gear during uphill climbs.
• Metal particles in transmission fluid: Flaking or chipped gear teeth shed ferrous debris into the oil, which can be detected during routine fluid changes as fine silver or dark metallic sludge.
• Hard shifting or delayed engagement: Worn gear profiles increase friction and binding, making it difficult to shift into forward gears or causing a noticeable delay when engaging from neutral.

Technical Specifications

Compatibility

This gear is specifically designed for ZF’s WG-series powershift transmissions. It is a direct replacement in the following models: WG100, WG130, and WG131. While primarily used in these three series, it may also be compatible with certain variants of the WG180 and WG200 transmissions that share the same countershaft layout. Always verify the existing gear’s tooth count and spline configuration before ordering. For differential-related repairs in these transmissions, the 5838109007 DIFFERENTIAL and 2095209019 DIFFERENTIAL are commonly replaced alongside this gear.

During installation, the 0750117075 TAPER ROLLER BEARING supports the gear’s axial loads, while the 0631329086 SPRING PIN secures the gear to its shaft. These components must be inspected and replaced if worn to prevent premature failure of the new gear.
