ZF 2095.346.046 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.346.046 SPUR GEAR is a critical power-transfer component located within the main gear train of ZF WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 2095.346.046, directly engages with the countershaft to modulate torque distribution between the input and output shafts. As a precision-machined spur gear, it ensures minimal backlash and consistent rotational force under heavy load conditions. When paired with a properly functioning 5838109007: DIFFERENTIAL, this gear maintains synchronized speed ratios across the drivetrain, preventing uneven wear on downstream components.

Symptoms of Failure

• Whining or howling noise during acceleration: A worn 2095.346.046 spur gear produces a distinct high-pitched whine, especially under load, indicating tooth surface pitting or chipping.
• Intermittent gear slipping under torque: When the spur gear’s teeth lose their profile, the transmission may momentarily lose engagement, causing a sudden RPM surge without corresponding vehicle speed increase.
• Metallic debris in transmission fluid: Flakes or silver particles found during oil changes directly point to spur gear degradation, often accompanied by a grinding sensation during gear shifts.
• Vibration at specific road speeds: A damaged gear creates harmonic vibrations that resonate through the chassis, typically between 30-50 mph, worsening as the 0750117075: TAPER ROLLER BEARING supporting the shaft also begins to fail.

Technical Specifications

Compatibility

This spur gear is engineered specifically for ZF’s WG100, WG130, and WG131 transmission models, commonly found in medium-duty trucks and industrial machinery. It is not interchangeable with WG180 or WG200 series units due to differing shaft diameters and tooth pitch. For proper assembly, this gear must be installed alongside a new 2095209019: DIFFERENTIAL and secured with a 0631329086: SPRING PIN to prevent axial movement. Always verify the gear’s backlash clearance (0.08-0.15 mm) during installation.
