Overview
The ZF 2094.310.054 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force between parallel shafts, ensuring synchronized gear engagement and consistent torque delivery. The SKU 2094.310.054 sits directly on the countershaft assembly, meshing with the main drive gear to support low-range and reverse operations. Constructed from case-hardened alloy steel, this spur gear maintains tight backlash tolerances critical for heavy-duty industrial applications.
Symptoms of Failure
- Whining or grinding noise during PTO engagement: Worn gear teeth cause irregular contact patterns, producing a high-pitched whine when the transmission is under load. This often indicates the 2094.310.054 spur gear has developed pitting or chipping.
- Intermittent gear slipping in low range: As the spur gear’s tooth profile degrades, the transmission may momentarily lose torque transfer, especially during hill climbs or heavy hauling. Operators report a sudden “jump” or loss of drive.
- Metallic debris in transmission fluid: Flakes or silver particles in the oil filter or drain plug signal advanced wear of the spur gear’s hardened surface. This symptom frequently accompanies failure of the 2094104412 MAIN SHAFT bearing surfaces.
- Oil leaks near the PTO housing: Excessive gear vibration can distort seals, leading to fluid seepage around the shift mechanism. This is often linked to a worn 2094206001 GEARSHIFT SHAFT bushing.

Frequently Asked Questions
Q: Can I replace the 2094.310.054 spur gear without removing the entire transmission?
A: Yes, in most WG100/WG130 applications, the spur gear is accessible after removing the PTO cover and shift housing. However, you must also inspect the 2094304054 MAIN SHAFT for wear, as damaged gear teeth often score the shaft surface.
Q: What is the typical service life of this spur gear under normal conditions?
A: With proper lubrication and no shock loading, the 2094.310.054 spur gear typically lasts 8,000–12,000 operating hours. Early replacement is recommended if you notice metallic debris in the oil.
Q: Does this part fit the ZF WG180 transmission?
A: Yes, the 2094.310.054 is compatible with WG180 units when used in the auxiliary drive position. Always cross-reference your transmission’s serial number with the 2094106010 SHIFT SYSTEM to confirm fitment.
