Overview
The ZF 4616.204.002 PLANET CARRIER is a critical load-bearing component within the WG 65 series transmission assembly. This OEM genuine part serves as the central hub that supports the planetary gears, distributing torque evenly across the gear set during power shifts. Located inside the main gear train, the planet carrier (SKU: 4616.204.002) directly interfaces with the 4616105415: OUTPUT shaft to ensure smooth rotational energy transfer. Precision-machined from high-strength alloy steel, this carrier maintains exact gear alignment under extreme thermal and mechanical stress, preventing premature wear in the drivetrain.
Symptoms of Failure
- Gear slipping under load: When the planet carrier wears, planetary gears lose alignment, causing intermittent slipping during acceleration or hill climbs.
- Metallic grinding noise from transmission: A worn carrier allows gear teeth to clash, producing a distinct grinding sound, especially in lower gears.
- Oil contamination with metal debris: Flaking or cracking of the carrier surface introduces fine steel particles into the transmission fluid, visible during oil changes.
- Vibration at highway speeds: Uneven carrier wear creates rotational imbalance, felt as persistent vibration through the chassis at 50+ mph.

Compatibility
This planet carrier is engineered for the ZF WG 65 series, but its design principles extend to several other ZF powershift transmissions. It is directly compatible with WG 65, WG 80, and WG 100 models. The carrier also fits select WG 120 and WG 150 variants when used with the correct 4616303144: OUTPUT FLANGE adapter. For proper installation, ensure the 4616101094: TRANSMISSION HOUSING is free of cracks, and use the specified 0636011038: HEXAGON SCREW for secure mounting. Always verify your transmission serial number against ZF’s compatibility chart before ordering.
