Overview
The ZF 2093.310.100 DOUBLE GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 2093.310.100, sits within the countershaft assembly where it meshes directly with the main drive gear to facilitate smooth torque multiplication and speed reduction. As a double-gear unit, it features two distinct gear sets machined from a single billet, ensuring precise alignment and minimal backlash during high-load operations. This component is frequently replaced alongside the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to restore full drivetrain integrity.
Symptoms of Failure
When the ZF 2093.310.100 DOUBLE GEAR begins to wear, operators typically notice these specific failure indicators:
- Whining or grinding noise during gear engagement – A high-pitched sound from the transmission housing, especially under load, indicates tooth surface pitting or chipping on the double gear.
- Intermittent gear slipping under acceleration – Worn gear teeth fail to maintain positive engagement, causing the transmission to momentarily lose torque delivery when climbing or hauling.
- Metallic debris in transmission fluid – Flakes or small fragments found during oil changes signal advanced wear of the gear flanks, often requiring immediate replacement of the 2093.310.100 unit.
- Vibration through the shift lever – Excessive axial play in the double gear set creates harmonic vibrations that transmit directly to the operator’s controls.

Compatibility
This OEM genuine DOUBLE GEAR is specifically designed for ZF WG-series transmissions. It is a direct fit for the following models:
- ZF WG100
- ZF WG130
- ZF WG131
While primarily intended for these three series, the 2093.310.100 may also be compatible with certain variants of the WG180 and WG200 transmissions where the countershaft gear geometry matches. For proper installation, always pair this gear with the 2093209023: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING to ensure correct axial clearance and oil flow.

Frequently Asked Questions
Q: How do I know if my ZF WG130 needs a new 2093.310.100 double gear?
A: If you hear a distinct “chattering” noise during deceleration or find metal particles on the transmission drain plug magnet, the double gear teeth are likely worn beyond service limits. Inspect the gear flanks for step wear or pitting before ordering a replacement.
Q: Can I install the 2093.310.100 without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously. Worn bearings introduce radial play that accelerates new gear wear, often leading to premature failure within 500 operating hours.
Q: Is the 2093.310.100 compatible with aftermarket differential housings?
A: This OEM double gear is machined to tight ZF tolerances. While it may physically fit aftermarket housings, we recommend using the genuine 5838300626: DIFFERENTIAL HOUSING to guarantee correct gear mesh depth and oil channel alignment.
