ZF 0635.300.204 NEEDLE CAGE for WG200 | OEM Genuine Part

Overview

The ZF 0635.300.204 NEEDLE CAGE is a precision-engineered component designed for the WG 200 Series transmissions. This OEM genuine part functions as a critical rolling element bearing assembly, reducing friction between rotating shafts and stationary housings within the planetary gear set. The needle cage ensures smooth torque transfer and maintains proper gear alignment under high-load conditions. Identified by SKU 0635.300.204, this component is essential for maintaining the structural integrity of the transmission’s clutch pack and planetary carrier assembly. When installed alongside the 4460165051: CONSOLE and 4460368311: CONSOLE, it forms a robust support system for the input shaft.

Symptoms of Failure

• Transmission whining noise during acceleration: A worn needle cage allows radial play, causing metallic grinding sounds that intensify under load.
• Delayed gear engagement or slipping: When the cage fails, roller skewing disrupts clutch pack compression, leading to hesitation between shifts.
• Metallic debris in transmission fluid: Flaking or fractured needle rollers contaminate the oil, often visible during drain intervals as silver particles.
• Vibration through the shift lever: Excessive bearing clearance transmits harmonic vibrations from the planetary gears to the chassis.

Technical Specifications

Compatibility

This needle cage is primarily engineered for the ZF WG200 transmission series, including models WG180, WG200, and WG210. It also fits select variants of the ZF Ecomat 4HP and 5HP series where the planetary carrier uses a 55mm inner race. Always verify fitment with your transmission’s parts manual. For complete rebuilds, pair this cage with the 0636011429: HEXAGON SCREW and 0730100365: WASHER to secure the bearing race.
