Overview
This genuine OEM ZF 2093.298.131 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the final drive assembly, this gear transfers rotational torque from the countershaft to the differential unit, directly influencing axle speed and load distribution. The part number 2093.298.131 is precision-machined to factory tolerances, ensuring seamless meshing with mating components. When installed alongside a 5838109012: DIFFERENTIAL, it maintains the correct gear lash and reduces parasitic power loss during high-torque operations.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct metallic whine that intensifies under load—a classic sign of a failing 2093.298.131 gear.
- Intermittent gear slippage under heavy load: As the gear surface degrades, it loses bite with the mating pinion, causing momentary loss of drive torque when climbing grades or hauling maximum payloads.
- Metallic debris in transmission oil: Flaking or pitting on the gear flanks sheds fine steel particles into the lubricant, often visible during routine oil changes as glitter-like contamination.
- Vibration through the driveline: Uneven wear on the gear’s helix angle induces cyclic vibrations that transmit through the axle housing, particularly noticeable at cruising speeds between 40–55 mph.

Compatibility
This gear is specifically designed for ZF WG-series powershift transmissions. Verified compatibility includes the WG100, WG130, and WG131 models. It also retrofits into the WG180 and WG200 series when used in conjunction with the correct 5838300626: DIFFERENTIAL HOUSING. For optimal longevity, always pair this gear with a fresh 0750117075: TAPER ROLLER BEARING to maintain proper preload and axial alignment. In dual-differential configurations, the 2093209023: DIFFERENTIAL serves as the direct mating partner for this gear.

Frequently Asked Questions
Q: Can the 2093.298.131 gear be installed without replacing the differential housing?
A: Yes, provided the housing bore is within factory wear limits. However, we strongly recommend inspecting the 5838300626: DIFFERENTIAL HOUSING for scoring or ovalization before reassembly.
Q: What is the typical service life of this gear in a WG130 transmission?
A: Under normal operating conditions with proper lubrication, the gear typically lasts 8,000–12,000 hours. Early failure often correlates with contaminated oil or a worn 0750117075: TAPER ROLLER BEARING that allows excessive gear movement.
Q: Does this gear require a specific break-in procedure?
A: Yes. After installation, run the transmission at 50% load for the first 2 hours, then perform a full heat-cycle cool-down. This allows the case-hardened surface to mate properly with the 2093209023: DIFFERENTIAL without galling.
