Overview
The ZF 4143.216.039 BEVEL GEAR SET is a precision-engineered OEM genuine component designed for the transfer of rotational power between non-parallel shafts within ZF’s heavy-duty WG100, WG130, and WG131 transmission series. This matched set of spiral bevel gears ensures smooth, quiet torque delivery from the input shaft to the countershaft, directly influencing driveline efficiency and load-holding capability. The SKU 4143.216.039 is manufactured to exacting OEM tolerances to maintain gear mesh patterns and reduce backlash, making it a critical element for any rebuild or overhaul of these industrial transmissions.
Symptoms of Failure
When the ZF 4143.216.039 bevel gear set begins to wear, operators often notice a distinct whining or howling noise from the transmission housing during acceleration or deceleration, a classic sign of gear tooth surface fatigue. Another common failure symptom is excessive backlash or clunking when shifting between forward and reverse, indicating that the gear teeth have developed pitting or chipping. You may also detect metal particles or glitter in the transmission oil filter during routine maintenance, which points directly to spalling on the bevel gear flanks. Finally, vibration through the driveline at specific RPM ranges can occur as the gear set loses its precise mesh alignment, often accelerating wear on adjacent components like the 4143101009 HOUSING and 4143301025 HOUSING.

Compatibility
This genuine ZF bevel gear set is specifically engineered for the WG100, WG130, and WG131 transmission families. It is also a direct replacement for units found in the HL 100 Series and HL 270 Series final drives. While primarily designed for these models, the 4143.216.039 may also be compatible with certain variants of the WG180 and WG200 transmissions that share the same gear train architecture. Always verify the existing gear set part number before ordering. During installation, it is critical to inspect and replace the 0634313603 O-RING and the 4475280018 SCREW PLUG to prevent fluid leaks and ensure proper sealing of the housing cavity.
