ZF 20743110331 PLANET CARRIER | OEM Genuine Part

Overview

The ZF 20743110331 PLANET CARRIER is a critical torque-transferring component located within the planetary gearset of heavy-duty ZF transmissions. This OEM genuine part serves as the structural hub that supports the planetary pinions and bearings, ensuring precise gear alignment under extreme load conditions. Designed for construction machinery applications, the SKU 20743110331 directly interfaces with the 2094101017: TRANSMISSION HOUSING and the 2094301069: HOUSING to form the core rotating assembly. Without this carrier, the transmission cannot achieve the necessary gear reduction for high-torque operations.

Symptoms of Failure

• Erratic gear engagement or slipping under load: A worn planet carrier causes misalignment of the planetary gears, leading to intermittent power loss during acceleration or climbing.
• Metallic grinding noises from the transmission housing: Damaged carrier bearing journals produce a distinct low-frequency rumble or grinding sound, especially in lower gears.
• Oil contamination with metallic debris: As the carrier wears, fine steel particles enter the lubricant, visible during oil changes as glitter-like contamination.
• Vibration through the driveline: Uneven wear on the carrier’s pinion pockets creates rotational imbalance, felt as shuddering at specific RPM ranges.

Technical Specifications

Compatibility

This planet carrier is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and telehandlers. Verified compatible models include WG180, WG200, and WG210 series. It also fits select 4WG-200 and 6WG-200 variants. The carrier works in conjunction with the 2094298054: HOUSING and is secured using the 0636302008: SCREW PLUG during final assembly. Always verify your transmission’s serial number before ordering.
