Overview
The ZF 4143.216.023 BEVEL GEAR SET is a critical power transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part precisely meshes with the countershaft to redirect torque at a right angle within the drop box assembly, ensuring smooth and reliable operation under heavy industrial loads. The SKU 4143.216.023 is manufactured to exacting ZF tolerances, featuring hardened steel teeth that withstand continuous high-torque applications. This bevel gear set works in conjunction with the 4143101009: HOUSING and the 4143301025: HOUSING to maintain proper gear alignment and oil containment within the transmission casing.
Symptoms of Failure
- Whining or howling noise during deceleration: Worn bevel gear teeth create a distinct high-pitched whine that intensifies when the vehicle slows down, indicating uneven tooth contact patterns.
- Vibration in the driveline at specific speeds: As the gear set loses its precise tooth geometry, you will feel a rhythmic shudder through the chassis, particularly between 30-45 mph under load.
- Metallic debris in transmission fluid: Flakes or silver particles found during oil changes signal advanced gear surface fatigue, often accompanied by a burnt gear oil odor.
- Intermittent gear slipping or clunking: Excessive backlash from a worn bevel gear set causes a delayed engagement or a sharp metallic clunk when shifting between forward and reverse.

Compatibility
This bevel gear set is specifically designed for ZF WG series transmissions with drop box configurations. It directly fits the WG100, WG130, and WG131 models. It is also compatible with the HL 100 Series and HL 270 Series transfer case assemblies. For proper installation, always replace the 0634313603: O-RING and the 4475280018: SCREW PLUG to prevent fluid leaks. This gear set is not interchangeable with WG180 or WG200 series units due to different shaft diameters and tooth profiles.
