Overview
This ZF 2093.346.059 GEAR is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. It functions as a critical drive element within the gear train, transferring torque from the input shaft to the differential assembly. The SKU 2093.346.059 is an OEM genuine part, ensuring exact fitment and load-bearing performance. It sits directly in the final drive housing, meshing with the AXLE BEVEL GEAR to convert rotational speed into usable axle power.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
- Metal particles in transmission oil: Flaking or pitting on the gear surface sheds debris into the lubricant, often visible during oil changes or as sludge on the drain plug.
- Intermittent gear slippage or loss of drive: Advanced wear reduces tooth engagement, causing momentary power loss, especially when climbing grades or carrying heavy loads.
- Vibration through the driveline: Uneven tooth wear or a cracked gear hub introduces cyclical vibrations felt in the chassis or steering wheel at specific speeds.

Compatibility
This gear is specifically designed for ZF WG-series powershift transmissions. It is a direct replacement for models WG100, WG130, and WG131. While the gear profile is unique to these three variants, it also shares the same spline interface and pitch circle as the differential assemblies used in WG180 and WG200 transmissions. For a complete rebuild, always pair this gear with the DIFFERENTIAL (2093109024) and the TAPER ROLLER BEARING (0750117075) to maintain proper preload and alignment.
During installation, the gear interfaces directly with the DIFFERENTIAL (2093209095) and is housed within the DIFF.HOUSING (2093309071). These components must be inspected for wear simultaneously to avoid premature failure of the new gear.

Frequently Asked Questions
Q: Can I install the 2093.346.059 gear without replacing the taper roller bearing?
A: It is strongly recommended to replace the TAPER ROLLER BEARING (0750117075) simultaneously. A worn bearing alters gear mesh geometry, accelerating wear on the new gear.
Q: What is the typical service life of this gear in a WG130 transmission?
A: Under normal operating conditions with proper lubrication, the gear lasts 8,000–12,000 hours. Frequent heavy loading or contamination can reduce this to 4,000–6,000 hours.
Q: Does this gear require any special tools for removal?
A> Yes, a bearing puller and a press are needed to separate the gear from the differential housing. The SPRING PIN (0631100223) must be driven out first to release the gear from the shaft.
