Overview
The ZF 4699.302.199 SPUR GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as a precision-machined gear that transfers rotational force between parallel shafts within the gear train, ensuring smooth torque delivery and consistent speed regulation. The SKU 4699.302.199 sits directly within the intermediate shaft assembly, where it meshes with corresponding gears to maintain proper gear ratios under heavy-duty industrial loads. Manufactured to ZF’s exacting tolerances, this spur gear is essential for maintaining drivetrain integrity in commercial vehicles and off-highway equipment.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn 4699.302.199 spur gear produces audible metallic sounds, particularly under load, indicating tooth surface degradation or pitting.
- Vibration through the transmission housing: As the gear teeth wear unevenly, you may feel rhythmic shaking in the chassis, signaling misalignment or backlash issues within the gear set.
- Intermittent power loss or gear slipping: When the spur gear’s teeth become chipped or excessively worn, the transmission may fail to maintain consistent torque transfer, leading to sudden RPM surges without corresponding vehicle movement.
- Metallic debris in transmission oil: Flakes or particles found during oil changes point directly to spur gear wear, requiring immediate inspection of the 4699.302.199 component.

Compatibility
This ZF 4699.302.199 spur gear is specifically designed for the WG100, WG130, and WG131 transmission models. Based on its gear geometry and spline configuration, it may also be compatible with the WG180 and WG200 series transmissions used in medium-duty trucks and construction machinery. Always verify the gear’s tooth profile and bore dimensions against your transmission’s service manual before installation. The part is not interchangeable with WG80 or WG250 series units without modification.
During replacement, the spur gear integrates directly with the 4699101099 HOUSING and the 4699301177 HOUSING, which support the gear’s bearing surfaces. The 4699301178 HOUSING COVER seals the assembly, while 0636102013 CAP SCREW fasteners secure the housing components. Proper torque on these fasteners is critical to prevent gear misalignment.
