ZF 4143.115.406 PLANETARY DRIVE | OEM Genuine Part

Overview

The ZF 4143.115.406 PLANETARY DRIVE is a critical torque-multiplying assembly within the HL 100 and HL 270 series transmissions. This OEM genuine component transfers rotational force from the input shaft to the output shaft while reducing speed and increasing torque. As the central gear train element, it directly engages with the 4143101031 HOUSING to maintain precise gear alignment. The SKU 4143.115.406 is engineered for high-load industrial applications, ensuring smooth power delivery under extreme stress.

Symptoms of Failure

• Intermittent gear slipping under load: When the planetary drive wears, you may experience sudden loss of torque during acceleration or uphill operation, often accompanied by a grinding noise.
• Metallic debris in transmission fluid: Worn planetary gears shed metal particles, causing oil discoloration and clogging the 4143301045 SCREEN SHEET.
• Abnormal vibration at specific RPM ranges: Damaged planet gears create harmonic vibrations that resonate through the 4143298040 CASE, often felt in the vehicle chassis.
• Oil leaks near the drive housing: Seal failure around the planetary drive allows fluid to escape past the 0631329135 SPRING PIN retention points.

Technical Specifications

Compatibility

This planetary drive is designed for ZF HL 100 and HL 270 series transmissions, including models WG180, WG200, and WG210. It also fits select off-highway transmissions in the 4WG-180 and 4WG-200 families. For proper installation, ensure the 4143301055 HOUSING is free of wear. Always replace the 0634303266 O-RING and 0636101024 CAP SCREW during reassembly to prevent fluid leaks.
