Overview
The ZF 2094.359.046 INPUT GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. As the primary gear receiving torque from the engine clutch, it directly engages with the countershaft to initiate the gear reduction sequence. This OEM genuine part (SKU: 2094.359.046) ensures precise meshing and minimal backlash, directly influencing shift quality and overall drivetrain efficiency. It is housed in the front section of the transmission case, where it interfaces with the 2094104412: MAIN SHAFT to distribute rotational force through the gear train.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn input gear produces a distinct high-pitched whine that increases with engine RPM, often mistaken for bearing noise.
- Hard shifting or gear clash: Damaged teeth prevent smooth engagement, causing the transmission to resist shifting or produce a grinding sound when moving into gear.
- Metal debris in transmission fluid: Flakes or particles found during oil changes indicate spalling on the input gear’s contact surface, requiring immediate replacement.
- Vibration through the shift lever: Excessive wear on the gear’s splines or tooth profile transmits harmonic vibrations into the cab, especially under load.

Compatibility
This input gear is specifically designed for ZF’s WG-series mechanical transmissions. It is a direct fit for the WG100, WG130, and WG131 models commonly found in medium-duty trucks, buses, and agricultural machinery. It also serves as a service replacement for early WG180 and WG200 variants when used with the correct 2094304054: MAIN SHAFT and 2094106010: SHIFT SYSTEM assembly. Always verify the tooth count and spline configuration against your existing unit before installation.

Frequently Asked Questions
Q: Can I install the 2094.359.046 input gear without replacing the main shaft?
A: Yes, but only if the existing MAIN SHAFT shows no spline wear or pitting. We strongly recommend inspecting the mating shaft for damage, as a worn input gear often indicates companion shaft wear.
Q: What is the typical service life of this input gear under normal conditions?
A: With proper lubrication and no shock loading, the OEM gear typically lasts 400,000–600,000 km. Early replacement is advised if any whining noise develops.
Q: Does this part include the snap ring or washer?
A: No. The 2094.359.046 is the gear only. You will need to order the SNAP RING and WASHER separately for a complete installation.
