Overview
The ZF 2094.359.040 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and PTO (Power Take-Off) gear train within ZF WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 2094.359.040, transfers rotational force from the main shaft to the shift system, ensuring synchronized engagement during gear changes. It sits directly on the countershaft assembly and meshes with the 2094104412: MAIN SHAFT to maintain consistent torque flow. Without this spur gear, the transmission cannot deliver power to secondary hydraulic systems or maintain proper gear alignment under load.
Symptoms of Failure
- Whining or grinding noise during PTO engagement: Worn teeth on the 2094.359.040 produce a high-pitched metallic sound, especially when engaging the auxiliary drive at low RPM.
- Intermittent gear slipping under load: A damaged spur gear causes the 2094106010: SHIFT SYSTEM to lose positive engagement, resulting in sudden power loss during acceleration.
- Metal particles in transmission fluid: Flaking or chipped gear teeth contaminate the oil, visible as glittering debris during routine drain intervals.
- Hard shifting between forward and reverse: Excessive backlash from a worn spur gear forces the 2094206001: GEARSHIFT SHAFT to struggle against misaligned splines.

Compatibility
This spur gear is specifically designed for ZF WG100, WG130, and WG131 series transmissions. It also fits select variants of the WG180 and WG200 models when used in conjunction with the 2094304054: MAIN SHAFT. Always verify your transmission serial number before ordering, as later WG200 units may require a different tooth profile.

Frequently Asked Questions
Q: Can the 2094.359.040 spur gear be replaced without removing the entire transmission?
A: Yes, on WG100 and WG130 models, the gear is accessible after removing the PTO cover and the 0630513070: SNAP RING. However, WG131 units may require partial disassembly of the shift housing.
Q: What is the typical lifespan of this spur gear under normal operating conditions?
A: With proper lubrication and no contamination, the OEM gear typically lasts 8,000–12,000 hours. Early replacement is recommended if metal debris is found in the oil filter.
Q: Does this part include the necessary snap ring or washer?
A: No, the 2094.359.040 is sold as a standalone gear. You will need to order the 2094306019: WASHER and snap ring separately for a complete installation.
