Overview
The ZF 2093.310.172 DOUBLE GEAR is a precision-engineered OEM genuine component designed for the auxiliary drive and countershaft assembly within ZF WG-series transmissions. This double gear transfers torque between the input shaft and the differential housing, playing a critical role in load distribution and gear ratio stability. The SKU 2093.310.172 is manufactured to exacting ZF tolerances, ensuring seamless meshing with adjacent gears and bearings. It sits directly in the lower gear train, working in tandem with the 2093109029: DIFFERENTIAL to manage power flow under heavy loads.
Symptoms of Failure
When the ZF 2093.310.172 DOUBLE GEAR begins to wear, operators may notice distinct operational issues. Whining or grinding noises during acceleration often indicate tooth surface degradation or pitting on the double gear. Intermittent gear slipping under load can occur when the gear’s helical teeth lose their profile, causing momentary loss of torque transfer. Metallic debris in the transmission oil filter is a clear sign of material fatigue, often accompanied by vibration at specific RPM ranges due to uneven wear on the gear’s dual faces. These symptoms typically worsen if the adjacent 0750117075: TAPER ROLLER BEARING is also failing, as bearing play accelerates gear misalignment.

Compatibility
This ZF 2093.310.172 DOUBLE GEAR is engineered for use in the WG100, WG130, and WG131 transmission models. It is also compatible with select WG180 and WG200 variants that share the same auxiliary drive architecture. The gear interfaces directly with the 2093209094: DIFFERENTIAL assembly and mounts within the 2093309078: DIFF.HOUSING. Always verify your transmission serial number before ordering, as later WG131 revisions may use a different tooth profile.

Frequently Asked Questions
Q: Can I replace the ZF 2093.310.172 DOUBLE GEAR without removing the entire transmission?
A: In most WG100/WG130/WG131 models, the double gear is accessible after removing the side cover and differential assembly. However, we recommend a full teardown inspection of the 0750117075: TAPER ROLLER BEARING and 2093309078: DIFF.HOUSING for hidden damage.
Q: How do I confirm this gear fits my WG131 transmission?
A: Check the stamped serial number on your transmission housing. The 2093.310.172 is standard for WG131 units built after 2012. Earlier units may require the 4482360001: DIFFERENTIAL BEVEL GEAR as a matched set.
Q: What torque specification is used for the retaining nut on this double gear?
A: The recommended tightening torque is 180 Nm for the main shaft nut, with Loctite 243 applied. Always replace the 0631100223: SPRING PIN during reassembly to prevent rotation.
