Overview
This genuine OEM ZF 2093.303.064 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. Situated within the gear train assembly, this part transmits torque and rotational motion between shafts, ensuring smooth power flow and precise gear engagement. The SKU 2093.303.064 is manufactured to exact ZF tolerances, providing reliable performance under heavy-duty industrial loads. When installed alongside the 2093101052 HOUSING, it forms a sealed, durable unit that withstands high stress and thermal expansion.
Symptoms of Failure
- Whining or grinding noise during gear shifts: Worn teeth on the 2093.303.064 gear create irregular contact patterns, producing audible metallic sounds, especially under load.
- Intermittent gear slipping or hesitation: As the gear surface degrades, it fails to maintain consistent engagement, causing momentary loss of power transmission.
- Metallic debris in transmission fluid: Flaking or pitting of the gear material contaminates the oil, often visible during routine drain intervals.
- Vibration through the driveline: Uneven wear on the gear profile introduces imbalance, felt as shuddering during acceleration or deceleration.

Compatibility
This gear is specifically designed for ZF WG100, WG130, and WG131 transmissions. It is also compatible with select variants of the WG180 and WG200 series when used in auxiliary drive configurations. For proper installation, the gear must be paired with the 2093298063 TRANSMISSION HOUSING and the 2093301069 TRANSMISSION HOUSING to ensure correct alignment and oil sealing. Always verify the 4475280015 SCREW PLUG is torqued to specification during reassembly to prevent fluid leaks.

Frequently Asked Questions
Q: How do I know if the 2093.303.064 gear is the correct replacement for my WG130 transmission?
A: Verify your transmission model plate (often listed as part 0730365092 TYPE PLATE). The gear is standard in WG100, WG130, and WG131 units; for WG180 or WG200, confirm the tooth count matches your existing gear.
Q: What other seals should I replace when installing this gear?
A: We recommend replacing the 0634304731 O-RING and the 0634314235 O-RING to ensure a leak-free assembly. Also inspect the 4475280150 SCREW PLUG for thread damage.
Q: Can I reuse the old 2093301033 COVER with a new gear?
A: Yes, provided the cover is not warped or cracked. However, always replace the 0636015073 HEXAGON SCREW if it shows signs of corrosion or stripping.
