ZF 4143.216.047 BEVEL GEAR SET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4143.216.047 BEVEL GEAR SET is a critical power-transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part precisely meshes within the differential housing to redirect rotational force from the driveshaft to the axle shafts at a right angle, enabling smooth torque delivery under heavy loads. The SKU 4143.216.047 is machined from case-hardened alloy steel to withstand high stress and thermal cycling. It is mounted directly inside the 4143101009: HOUSING and sealed by the 0634313603: O-RING to prevent lubricant loss, while the 4475280018: SCREW PLUG secures the assembly access point.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth create uneven contact patterns, producing a distinct high-pitched sound that intensifies under load.
• Vibration in the driveline at low speeds: Excessive backlash from a degraded bevel gear set causes rhythmic shaking felt through the chassis.
• Metallic debris in transmission oil: Flaking or pitting on the gear surfaces sheds particles that contaminate the lubricant, often visible during drain intervals.
• Intermittent gear slipping or clunking: Advanced wear leads to sudden loss of torque transfer, accompanied by a sharp metallic impact when engaging gears.

Technical Specifications

Compatibility

This bevel gear set is designed for ZF WG-series powershift transmissions, specifically the WG100, WG130, and WG131 models. It also fits select HL 100 and HL 270 series transfer cases that share the same differential architecture. For proper installation, ensure the 4143301025: HOUSING is free of cracks and the mating surfaces are clean. The gear set is not interchangeable with WG180 or WG200 units without verifying housing dimensions.
