ZF 2094.304.076 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.304.076 SPUR GEAR is a precision-machined OEM component engineered for the auxiliary drive train of ZF WG100, WG130, and WG131 transmissions. This gear transmits rotational torque from the input shaft to the intermediate shaft, directly influencing gear ratio stability and load distribution. As a genuine OEM part (SKU: 2094.304.076), it ensures exact tooth geometry and surface hardness required for long-term reliability in heavy-duty industrial applications. When installed alongside the 2094009020: T 7336 L thrust washer, it maintains axial clearance within factory tolerances.

Symptoms of Failure

• Audible whining or grinding noise during gear engagement – Worn tooth flanks on the spur gear create irregular contact patterns, producing a high-pitched whine under load.
• Intermittent gear slipping under torque – Excessive backlash from tooth wear causes momentary loss of power transfer, especially during acceleration or hill climbing.
• Metallic debris in transmission oil – Pitting or spalling on the gear surface sheds microscopic metal particles, which can be detected during routine oil analysis.
• Vibration at specific RPM ranges – Uneven tooth wear induces harmonic vibration that resonates through the 2094101017: TRANSMISSION HOUSING, often misdiagnosed as bearing failure.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF WG100, WG130, and WG131 series transmissions. It also fits select variants of the WG180 and WG200 models where the auxiliary drive configuration matches the 32-tooth spline pattern. Always verify the gear mesh with the 2094298054: HOUSING and 2094301069: HOUSING to confirm correct alignment before installation. The gear is not backward-compatible with pre-1990 WG80 series units.
