Overview
The ZF 2093.368.087 SPUR GEAR is a precision-machined helical gear responsible for transferring torque from the input shaft to the countershaft in ZF WG100, WG130, and WG131 transmissions. This OEM genuine part, identified by SKU 2093.368.087, sits directly within the gear train assembly and ensures smooth power delivery under heavy loads. It works in concert with the 5838109012: DIFFERENTIAL to manage speed differentials between axles, while the 0750117075: TAPER ROLLER BEARING supports its rotational stability. When paired with the 2093209023: DIFFERENTIAL, this spur gear maintains consistent gear mesh alignment, reducing wear across the entire drivetrain.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth produce a distinct high-pitched sound, especially under load, indicating surface fatigue or pitting on the 2093.368.087 spur gear.
- Transmission slipping out of gear: Excessive backlash from a damaged spur gear causes intermittent power loss, often mistaken for clutch issues.
- Metal particles in transmission fluid: Flaking or chipped teeth shed metallic debris into the oil, which can clog filters and damage the 5838300626: DIFFERENTIAL HOUSING.
- Vibration at specific RPM ranges: Uneven tooth wear creates harmonic vibrations that resonate through the gearbox, worsening over time.

Frequently Asked Questions
Q: Can I replace the 2093.368.087 spur gear without removing the entire transmission?
A: Yes, but only if you have access to the side cover and countershaft. In most WG100/WG130 installations, the gear can be swapped after removing the differential housing and bearing support. Always replace the 0750117075: TAPER ROLLER BEARING simultaneously to prevent premature wear.
Q: What causes premature failure of this spur gear?
A: Contaminated oil with abrasive particles is the primary cause. A failing 5838300626: DIFFERENTIAL HOUSING can allow debris ingress. Additionally, incorrect backlash adjustment or a worn 2093209023: DIFFERENTIAL can induce uneven loading.
Q: Is the 2093.368.087 gear interchangeable with any aftermarket parts?
A: No. This OEM genuine part has specific tooth geometry and heat treatment that aftermarket copies rarely match. Using non-OEM gears often leads to accelerated wear of the 5838109012: DIFFERENTIAL and increased noise.
