Overview
The ZF 4699.302.245 SPUR GEAR is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits torque between parallel shafts within the gear train, ensuring smooth power flow and consistent gear engagement. As a critical element in the planetary gearset, it directly influences shift quality and load distribution. The SKU 4699.302.245 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged gears in heavy-duty industrial applications.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn tooth profiles on the 4699.302.245 spur gear produce a high-pitched whine or metallic grinding sound, especially under load. This is a common long-tail search query for operators experiencing transmission noise.
- Intermittent gear slipping under heavy torque: As the spur gear’s teeth wear unevenly, the transmission may momentarily lose power transfer, causing sudden RPM surges or hesitation during acceleration.
- Metallic debris in transmission oil: Flaking or pitting on the gear surface introduces fine metal particles into the lubricant, often detected during routine oil changes or filter inspections.
- Vibration through the driveline: A damaged spur gear creates imbalance in the rotating assembly, leading to noticeable chassis vibration at specific speed ranges.

Compatibility
This spur gear is specifically designed for the ZF WG100, WG130, and WG131 transmissions. It also serves as a replacement in the WG180 and WG200 series when used in auxiliary drive configurations. The 4699.302.245 interfaces directly with the countershaft assembly and is secured within the main HOUSING (4699101086). During installation, the gear must be aligned with the secondary HOUSING (4699301223) to ensure proper meshing. Lubrication points are sealed using a SCREW PLUG (0636302022) and a SCREW PLUG (0501319149) to prevent oil loss. Always verify transmission serial numbers before ordering.
