ZF 4143.115.400 PLANETARY DRIVE | OEM Genuine Part

Overview

The ZF 4143.115.400 PLANETARY DRIVE is a critical OEM genuine component engineered for the HL 100 and HL 270 series transmission assemblies. This planetary gear set functions as the primary torque multiplication stage, converting high-speed input from the turbine shaft into usable low-speed, high-torque output for the final drive. Positioned directly within the main gear train, the SKU 4143.115.400 ensures precise gear meshing and load distribution under extreme operational stresses. Its robust construction directly supports the structural integrity of the surrounding 4143101025: HOUSING and the 4143301055: HOUSING, which enclose and protect the planetary assembly from contamination.

Symptoms of Failure

When the ZF 4143.115.400 planetary drive begins to wear, operators will notice distinct performance degradation. Look for these specific failure indicators:

• Whining or grinding noise during acceleration: Worn planetary gears produce a high-pitched whine or metallic grinding, especially under load, indicating pitting or tooth surface fatigue.
• Intermittent gear slipping under heavy torque: A failing planetary drive cannot maintain positive engagement, causing the transmission to momentarily lose power or “hunt” for a gear ratio.
• Metallic debris in transmission fluid: Flakes or fine metal particles in the oil pan signal advanced wear of the sun gear or planet carrier bearings.
• Erratic shift timing or harsh engagement: Damaged planetary components disrupt hydraulic pressure feedback, leading to delayed or jarring shifts.

Technical Specifications

Compatibility

This planetary drive is engineered for ZF’s HL series powershift transmissions. It is a direct fit for the HL 100 and HL 270 series models commonly used in construction and agricultural machinery. Additionally, it is compatible with the WG180 and WG200 series transmissions where planetary reduction is required. The assembly integrates with the 4143298040: CASE which houses the gear train, and is secured using the 0631329135: SPRING PIN for precise alignment. For complete rebuilds, verify fitment with your specific transmission serial number.
