ZF 2074.311.034 PLANET CARRIER | OEM Genuine Part

Overview

The ZF 2074.311.034 PLANET CARRIER is a critical rotating assembly within the planetary gear set of heavy-duty construction machinery transmissions. As an OEM genuine part, it serves as the structural hub that holds the planetary gears in precise alignment, transmitting torque from the sun gear to the ring gear while managing immense loads during shifting and operation. This component is housed deep inside the transmission casing and works in concert with the 2094101012: TRANSMISSION HOUSING to ensure smooth power flow. The SKU 2074.311.034 is engineered to exact ZF tolerances, guaranteeing proper gear mesh and long service life under extreme conditions.

Symptoms of Failure

When the ZF 2074.311.034 planet carrier wears out, operators may notice distinct operational issues. Gear slipping under load is a primary indicator, often accompanied by a grinding noise during acceleration or when climbing grades. Metallic debris in the transmission oil signals that the carrier’s bearing surfaces or gear pockets have begun to spall. Another common symptom is erratic shifting or delayed engagement, as the worn carrier allows planetary gears to misalign. Finally, vibration through the chassis at specific RPM ranges points to imbalance or fatigue cracks in the carrier structure. If you observe these signs, inspect the 2094301036: HOUSING and 2094298057: HOUSING for collateral damage.

Technical Specifications

Compatibility

This planet carrier is designed for integration into ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and dump trucks. It is a direct fit for the ZF WG180 and ZF WG200 transmission models. It also appears in certain variants of the ZF WG150 and ZF WG210 series, particularly in applications requiring higher torque capacity. Always verify the transmission serial number before installation. During replacement, ensure the 2094301071: COVER is properly sealed to prevent contamination.
