ZF 4143.216.035 BEVEL GEAR SET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4143.216.035 BEVEL GEAR SET is a precision-engineered component designed for the transfer of rotational power between non-parallel shafts within the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 4143.216.035, is critical for maintaining correct gear mesh and torque distribution in the driveline. It sits within the gear cluster, interfacing directly with the 4143101009: HOUSING and the 4143301025: HOUSING to ensure stable alignment under load. Without this bevel gear set, the transmission cannot achieve the necessary speed reduction or directional change required for heavy-duty industrial applications.

Symptoms of Failure

• Whining or grinding noise during gear engagement: As the bevel gear teeth wear, they produce a distinct high-pitched whine or grinding sound, especially under load or during turns. This is a common long-tail search query for “ZF transmission whining noise.”
• Vibration in the driveline at specific speeds: Worn gear teeth cause uneven power transfer, leading to noticeable vibrations that can be felt through the chassis or shift lever, often searched as “transmission vibration at highway speeds.”
• Metal particles in transmission fluid: Flaking or pitting of the bevel gear surfaces introduces metallic debris into the oil, which can be detected during routine fluid changes. This symptom is frequently queried as “metal shavings in transmission fluid.”
• Intermittent gear slipping or loss of torque: When the gear set loses its precise mesh, the transmission may momentarily slip out of gear or fail to deliver full power, a condition often searched as “transmission slipping under load.”

Technical Specifications

Compatibility

This bevel gear set is specifically engineered for the ZF WG100, WG130, and WG131 transmission models. It is also a direct fit for the HL 100 Series and HL 270 Series gearboxes, which share the same bevel gear architecture. While primarily designed for these series, it may be retrofitted into certain WG180 and WG200 variants with careful verification of housing dimensions. For proper installation, ensure the 0634313603: O-RING is replaced to prevent fluid leaks, and the 4475280018: SCREW PLUG is torqued to specification to secure the assembly.
