ZF 5838.300.003 NEEDLE CAGE | OEM Genuine Part

Overview

The ZF 5838.300.003 NEEDLE CAGE is a precision-engineered OEM genuine component designed to maintain correct roller spacing and load distribution within ZF powershift transmissions. This needle cage sits directly between planetary gear sets and shaft assemblies, reducing friction and preventing metal-to-metal contact during high-torque operations in construction machinery. As a critical wear item, the SKU 5838.300.003 ensures that needle rollers remain evenly spaced, directly supporting the longevity of adjacent components such as the 5838109007: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Transmission whining or grinding noise during gear engagement: A worn needle cage allows roller skewing, producing audible metallic sounds under load.
• Intermittent gear slippage in forward or reverse: Damaged cages disrupt planetary gear alignment, causing power loss and erratic shifting.
• Metallic debris in transmission oil filter: Flaking or fractured cage material contaminates the lubrication system, accelerating wear on the 2095209019: DIFFERENTIAL assembly.
• Vibration through driveline during low-speed operation: Uneven roller spacing creates rotational imbalance, felt as chassis shudder.

Technical Specifications

Compatibility

This needle cage is primarily used in ZF WG180, WG200, and WG211 powershift transmissions found in wheel loaders, graders, and dozers. It also fits select ZF 4WG-200 and 6WG-200 series units. Always verify fitment with your transmission serial number. For complete rebuilds, pair this cage with the 0631329086: SPRING PIN to secure planetary carriers.
