ZF 4660.271.003 ROLLER CAGE for WG92 | OEM Genuine Part

Overview

The ZF 4660.271.003 ROLLER CAGE is a precision-engineered component designed for the WG92 and WG98 series of heavy-duty transmissions. This OEM genuine part functions as a critical guide and retention system for the needle rollers within the planetary gearset, ensuring correct roller spacing and load distribution during high-torque operations. Positioned inside the main gear assembly, the roller cage reduces friction between rotating elements and maintains alignment under extreme stress. The SKU 4660.271.003 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life when paired with a properly sealed TRANSMISSION HOUSING.

Symptoms of Failure

• Gear slipping under load: A worn roller cage allows needle rollers to misalign, causing intermittent power loss during acceleration or climbing.
• Metallic grinding noise from the transmission: When the cage fractures or deforms, rollers contact the HOUSING II, producing a distinct scraping sound during gear changes.
• Increased operating temperature: Failed roller cages create excessive friction, leading to localized overheating and degraded transmission fluid.
• Oil contamination with metallic debris: Cage fragments shed into the lubricant, often visible during routine drain inspections as silver or brass-colored particles.

Technical Specifications

Compatibility

This roller cage is engineered for ZF WG92 and WG98 series transmissions, commonly installed in WG180, WG200, and WG250 models. It directly replaces the original factory component in planetary gear stages requiring a 24-roller configuration. Always verify the cage condition when servicing the CYLINDRICAL PIN that secures the planetary carrier. For proper identification, cross-reference the transmission’s TYPE PLATE to confirm series compatibility before installation.
