Overview
The ZF 2093.310.098 SPUR GEAR is a precision-engineered component designed for the power-dividing section of ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force between parallel shafts within the gear train, ensuring smooth torque distribution to the differential assembly. As a critical element in the driveline, the spur gear (SKU: 2093.310.098) works in direct conjunction with the 2093109013: DIFFERENTIAL to manage load sharing under heavy-duty operation. Its hardened tooth profile maintains mesh integrity even under sustained high-torque conditions, making it indispensable for commercial vehicle applications.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn tooth flanks 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 degradation.
- Vibration in the driveline at cruising speeds: As the gear surface pits or spalls, rotational imbalance develops, transmitting vibration through the transmission housing and into the chassis.
- Intermittent gear slipping or power loss: Excessive backlash caused by tooth wear prevents consistent torque transfer, leading to momentary loss of drive engagement, especially when climbing grades.
- Metallic debris in transmission fluid: Flaking material from the spur gear contaminates the oil, which can accelerate wear on the 0750117075: TAPER ROLLER BEARING and other rotating elements.

Compatibility
This spur gear is engineered specifically for ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 variants when used in the input shaft cluster. The gear interfaces directly with the 2093209096: DIFFERENTIAL and is housed within the 2093309073: DIFF.HOUSING. Always verify the tooth count and shaft spline configuration before installation, as minor variations exist between early and late production models.

Frequently Asked Questions
Q: Can the ZF 2093.310.098 spur gear be used in a WG200 transmission?
A: Yes, the gear is compatible with WG200 models, but you must confirm the input shaft spline count and gear ratio match your specific unit. We recommend cross-referencing your old gear’s tooth count before ordering.
Q: What causes premature wear on this spur gear?
A: The most common cause is inadequate lubrication or contaminated transmission fluid. Metal particles from a failing 0750117075: TAPER ROLLER BEARING can embed in the gear teeth, accelerating pitting and spalling.
Q: Should I replace the thrust washers when installing a new spur gear?
A: Absolutely. We strongly advise replacing the 0730300820: THRUST WASHER and 5838300811: THRUST WASHER simultaneously to maintain proper end-play tolerances and prevent uneven gear loading.
