ZF 2094.322.053 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.322.053 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmissions. This OEM genuine gear transfers rotational force from the input shaft to the hydraulic pump or secondary output, ensuring consistent torque delivery under load. The part number 2094.322.053 is manufactured to ZF’s original tolerances, guaranteeing direct fitment and long service life. It sits directly on the countershaft cluster, meshing with the 2094009020: T 7336 L sleeve to synchronize gear engagement.

Symptoms of Failure

• Whining or grinding noise during PTO engagement — Worn spur gear teeth produce a high-pitched metallic sound, especially under load, indicating surface fatigue or chipping.
• Intermittent power loss to auxiliary hydraulics — A damaged gear fails to maintain constant mesh, causing the pump to lose pressure and resulting in sluggish or erratic equipment operation.
• Metal debris in transmission fluid — Flaking or pitting on the gear face sheds ferrous particles into the oil, which can be detected during routine drain intervals.
• Vibration through the shift lever or chassis — Uneven wear on the spur gear creates rotational imbalance, transmitting noticeable shudder through the driveline at specific RPM ranges.

Technical Specifications

Compatibility

This spur gear is specifically designed for the ZF WG100, WG130, and WG131 transmission series. It is also compatible with the WG180 and WG200 models when used in the auxiliary drive position. The gear interfaces directly with the 2094101017: TRANSMISSION HOUSING and the 2094298054: HOUSING assembly. For proper sealing, ensure the 2094301069: HOUSING cover is torqued to factory specifications during reinstallation.
