ZF 4143.216.028 BEVEL GEAR SET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4143.216.028 BEVEL GEAR SET is a precision-engineered component designed for the transfer of torque between non-parallel shafts within the ZF WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 4143.216.028, sits at the heart of the gear train, converting rotational power from the input shaft to the output shaft with minimal energy loss. Its hardened steel construction ensures durability under high-load conditions, making it critical for smooth drivetrain operation in industrial and marine applications. When installed correctly, this bevel gear set works in concert with the 4143101009: HOUSING and the 4143301025: HOUSING to maintain proper gear alignment and oil containment.

Symptoms of Failure

When the ZF 4143.216.028 bevel gear set begins to wear, operators may notice distinct performance issues. Common failure symptoms include:

• Whining or grinding noise during gear engagement – This indicates tooth surface pitting or misalignment, often heard at low speeds.
• Vibration in the transmission housing – Worn gear teeth create uneven load distribution, causing noticeable shaking through the chassis.
• Oil leaks near the gear mesh area – Degraded seals, such as the 0634313603: O-RING, can allow lubricant to escape, accelerating gear wear.
• Intermittent gear slipping under load – This occurs when the bevel gear set loses its tooth contact pattern, reducing torque transfer efficiency.

Technical Specifications

Compatibility

This bevel gear set is specifically engineered for ZF transmissions in the HL 100 and HL 270 series. It is a direct fit for the following models: WG100, WG130, WG131, WG180, and WG200. It also applies to the WG250 and WG270 series when used in conjunction with the correct 4475280018: SCREW PLUG for oil retention. Always verify your transmission serial number before ordering to ensure proper gear mesh alignment.
