Overview
This ZF 2093.368.142 SPUR GEAR is a critical power transmission component engineered specifically for the WG100, WG130, and WG131 series transmissions. Positioned within the countershaft assembly, this gear directly engages with the differential system to transfer rotational force from the input shaft to the output drive. As an OEM genuine part, SKU 2093.368.142 ensures precise tooth geometry and metallurgical integrity, maintaining the factory-specified backlash and load distribution. When installed alongside a 2093109013: DIFFERENTIAL, this spur gear forms the primary reduction stage that dictates overall gear ratio performance.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn tooth profiles on the spur gear create irregular contact patterns, producing a distinct metallic whine that intensifies under load. This is often the first audible sign of gear fatigue.
- Vibration through the shift lever or chassis: As the gear teeth develop pitting or spalling, the resulting imbalance transmits vibration directly into the transmission housing, felt as a low-frequency shudder during coasting.
- Metal particles in transmission fluid: Flaking or chipped gear teeth shed ferrous debris into the oil sump. If you observe glitter-like particles during fluid changes, the spur gear surface has begun to degrade.
- Intermittent gear slipping under heavy torque: Advanced wear reduces tooth engagement depth, causing the gear to momentarily skip under high-load conditions, particularly during uphill climbs or when towing.

Compatibility
This spur gear is designed for the ZF WG100, WG130, and WG131 series transmissions, commonly found in medium-duty trucks, buses, and agricultural equipment. It is not compatible with the WG180 or WG200 series due to differing shaft center distances and tooth modules. For proper installation, ensure the mating 0750117075: TAPER ROLLER BEARING is replaced simultaneously to maintain correct axial preload. The gear also interfaces with the 2093209096: DIFFERENTIAL and the 2093309073: DIFF.HOUSING to complete the final drive assembly.

Frequently Asked Questions
Q: Can I replace only the spur gear without replacing the mating differential?
A: While possible, it is strongly recommended to inspect and replace the 2093109013: DIFFERENTIAL simultaneously. Worn differential gears will accelerate wear on a new spur gear due to mismatched contact patterns.
Q: What is the expected service life of this spur gear under normal conditions?
A: With proper lubrication and regular fluid changes, the ZF 2093.368.142 typically lasts 300,000 to 500,000 kilometers. Premature failure often results from contaminated oil or a failing 0750117075: TAPER ROLLER BEARING that allows shaft deflection.
Q: Does this gear require special tools for installation?
A: Yes, a bearing puller and a press are needed to remove the old gear and seat the new one. The 0631100223: SPRING PIN must also be replaced to ensure proper locking.
