ZF 4108.202.004 PLANET CARRIER | OEM Genuine Part

Overview

The ZF 4108.202.004 PLANET CARRIER is a critical rotating assembly within the planetary gear set of ZF heavy-duty transmissions. This OEM genuine part supports the planetary gears and sun gear, distributing torque evenly across the gear train. Located inside the main transmission housing, the planet carrier ensures smooth power flow from the engine to the driveline. The SKU 4108.202.004 is precision-machined to OEM tolerances, making it essential for maintaining gear alignment and load capacity in construction machinery applications. When paired with the 4108101031: HOUSING and the 4108303155: HOUSING, this carrier forms the core of the planetary assembly.

Symptoms of Failure

• Gear slipping under load: A worn planet carrier can cause the planetary gears to misalign, leading to intermittent power loss or slipping during acceleration.
• Metallic grinding noise from transmission: Excessive bearing play or carrier cracking produces a distinct grinding sound, especially in lower gears.
• Oil contamination with metal shavings: As the carrier wears, metal particles enter the transmission fluid, visible during oil changes or filter inspections.
• Vibration during operation: Imbalanced carrier rotation creates noticeable vibration through the chassis, worsening at higher RPMs.

Technical Specifications

Compatibility

This planet carrier is designed for ZF WG-series and ERGOPOWER transmissions commonly used in construction machinery. Estimated compatible models include WG180, WG200, and WG211 series, as well as certain Ecomat 4HP variants. Always verify fitment with your transmission serial number. The carrier integrates with the 0636302015: SCREW PLUG for oil retention and the 0630361037: SEALING CAP to prevent debris ingress.
