ZF 2094.303.052 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.303.052 GEAR is a precision-engineered helical gear designed for the auxiliary drive and power take-off (PTO) circuits within the WG100, WG130, and WG131 transmission series. This OEM genuine component transfers rotational force from the main shaft to the shift system, ensuring smooth engagement of forward and reverse gears under heavy load. The SKU 2094.303.052 is manufactured to ZF’s strict tolerances, featuring case-hardened alloy steel that resists pitting and wear in high-torque applications. It sits directly on the countershaft assembly, meshing with the 2094104412: MAIN SHAFT to maintain consistent gear mesh alignment.

Symptoms of Failure

• Whining or grinding noise during gear engagement: Worn teeth on the 2094.303.052 gear produce a high-pitched whine, especially when shifting from neutral to drive under load.
• Intermittent power loss in auxiliary circuits: A chipped or spalled gear face causes the PTO to slip, leading to erratic hydraulic pump output and delayed implement response.
• Metal debris in transmission oil filter: Flaking from the gear’s hardened surface contaminates the lubrication system, often detected during routine oil analysis or filter inspection.
• Hard shifting or gear clash: Excessive backlash between this gear and the 2094304054: MAIN SHAFT creates a clunking sensation when selecting gears, worsening as the tooth profile degrades.

Technical Specifications

Compatibility

This gear is engineered for the ZF WG series powershift transmissions used in agricultural tractors and construction loaders. It is a direct fit for the WG100, WG130, and WG131 models. The 2094.303.052 also integrates with the WG180 and WG200 series when used in the auxiliary drive train, though verification of the shift system configuration is recommended. It works in conjunction with the 2094106010: SHIFT SYSTEM and the 2094206001: GEARSHIFT SHAFT to synchronize clutch pack engagement.
