ZF 2094.304.044 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.304.044 GEAR is a precision-machined helical gear engineered for the auxiliary drive train of ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part transmits torque from the input shaft to the intermediate shaft cluster, directly influencing gear ratio stability and load distribution under heavy-duty cycles. As a critical component within the Gears & Shafts category, the SKU 2094.304.044 ensures synchronized engagement when paired with the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT. Its hardened tooth profile minimizes backlash, making it indispensable for construction and agricultural machinery that demands consistent power delivery.

Symptoms of Failure

• Audible whining or grinding noise during gear engagement — Worn tooth flanks on the 2094.304.044 gear create uneven contact patterns, producing a high-pitched whine that intensifies under load. This is a common long-tail search query for “ZF transmission whining noise when shifting.”
• Intermittent gear slipping under moderate torque — As the gear’s helix angle degrades, the 2094106010: SHIFT SYSTEM cannot maintain positive engagement, leading to momentary power loss during uphill climbs or heavy pulling.
• Metallic debris in transmission oil filter — Flaking from the gear’s case-hardened surface contaminates the lubrication circuit. Operators searching for “metal shavings in ZF transmission oil” often trace the issue to this part.
• Increased operating temperature near the gear cluster — Excessive friction from a worn 2094.304.044 gear generates localized heat, which can warp adjacent components like the 2094206001: GEARSHIFT SHAFT.

Technical Specifications

Compatibility

This gear is specifically designed for the ZF WG100, WG130, and WG131 transmission series, which are commonly found in wheel loaders, forklifts, and telehandlers. While the 2094.304.044 is not used in the larger WG180 or WG200 models due to different shaft center distances, it shares the same tooth profile as the intermediate gear in the WG150 series. For proper installation, always verify the gear’s axial clearance using the 0630513070: SNAP RING and the 2094306019: WASHER to prevent end-play. The 0732040444: COMPRESSION SPRING and 0732040728: COMPRESSION SPRING are also used in the shift rail assembly that interacts with this gear.
