Overview
The ZF 2093.310.171 DOUBLE GEAR is a critical OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This precision-machined gear serves as an intermediate power transfer element within the countershaft assembly, facilitating smooth torque distribution between the input shaft and the differential system. The SKU 2093.310.171 is designed to withstand high cyclic loads and thermal expansion, ensuring consistent meshing with mating gears. When installed alongside a 2093109029: DIFFERENTIAL, this double gear optimizes driveline efficiency in heavy-duty industrial applications.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth on the 2093.310.171 produce a distinct metallic whine, especially under load, indicating uneven tooth contact.
- Intermittent gear slipping under torque: A failing double gear can cause momentary loss of power transfer, often misdiagnosed as clutch issues, due to worn splines or pitted tooth flanks.
- Metallic debris in transmission oil: Flaking or spalling of the gear surface introduces fine steel particles into the lubricant, accelerating wear on the 0750117075: TAPER ROLLER BEARING and adjacent components.
- Vibration at specific RPM ranges: Imbalanced gear rotation from uneven wear creates resonant vibrations that can be felt through the gearshift lever or chassis.

Frequently Asked Questions
Q: Can the ZF 2093.310.171 DOUBLE GEAR be used in a WG180 transmission?
A: Yes, but only when paired with the correct differential housing (2093309078) and taper roller bearing (0750117075). Always cross-reference your transmission’s parts manual for specific variant compatibility.
Q: How do I identify a worn double gear without disassembling the transmission?
A: Listen for a rhythmic clicking sound during deceleration and check the oil filter for metallic particles. A borescope inspection through the fill plug can reveal tooth pitting on the 2093.310.171 gear face.
Q: What torque specification should I use for the retaining nut on this gear?
A: ZF specifies 180 Nm (133 ft-lbs) for the locknut securing the double gear to the countershaft. Always replace the spring pin (0631100223) during reassembly to prevent loosening.
