ZF 4143.115.012 PLANETARY DRIVE | OEM Genuine Part

Overview

The ZF 4143.115.012 PLANETARY DRIVE is a critical OEM genuine component engineered for the HL 100 and HL 270 series transmissions. This planetary gear set is responsible for torque multiplication and speed reduction within the transmission’s final drive assembly. Positioned between the main gearbox and the output shaft, the 4143.115.012 ensures smooth power delivery under heavy loads. As a genuine ZF part, it guarantees precise fitment and long service life. The SKU 4143.115.012 is often replaced in conjunction with the 4143101016: HOUSING and the 4143301039: HOUSING to maintain structural integrity of the assembly.

Symptoms of Failure

• Grinding or whining noise during gear engagement: Worn planetary gears produce a distinct metallic sound, especially under load or when turning.
• Intermittent gear slipping or loss of torque: A failing planetary drive may cause the transmission to momentarily lose power, particularly in lower gears.
• Metal particles in transmission fluid: Debris from the planetary gears contaminates the oil, often visible during routine fluid changes.
• Vibration or shuddering at low speeds: Uneven wear on the planetary carrier leads to driveline vibrations that worsen over time.

Technical Specifications

Compatibility

This planetary drive is designed for use in ZF HL 100 and HL 270 series transmissions. It is also a direct replacement for units found in WG180, WG200, and WG210 models that utilize the same planetary carrier design. Always verify your transmission serial number before ordering. For complete assembly, pair this part with the 0501318136: GASKET and 0636101084: CAP SCREW to ensure a leak-free installation.
