ZF 4660.273.013 ROLLER CAGE for WG92/WG98 | OEM Genuine Part

Overview

The ZF 4660.273.013 ROLLER CAGE is a precision-engineered component designed for the internal planetary gearset of the WG92 and WG98 transmission series. This OEM genuine part functions as the retaining framework for needle rollers, ensuring correct roller spacing and load distribution within the gear assembly. The SKU 4660.273.013 sits directly between the sun gear and the planetary carrier, where it minimizes friction and prevents metal-to-metal contact during high-torque shifts. Without this cage, the roller bearings would lose alignment, leading to accelerated wear on the 4950101004: HOUSING and the 4950301018: HOUSING I.

Symptoms of Failure

• Erratic gear engagement or slipping under load — When the roller cage fractures, needle bearings can skew, causing intermittent power loss during acceleration.
• Metallic grinding noise from the transmission sump — A worn 4660.273.013 cage allows rollers to rub against the 4660101023: TRANSMISSION HOUSING, producing a distinct whine or grind.
• Contaminated oil with bronze or steel particles — Cage degradation sheds debris that circulates through the system, often clogging the filter and damaging the 0734309932: SHAFT SEAL.
• Increased operating temperature — Friction from misaligned rollers generates excess heat, which can warp adjacent components.

Technical Specifications

Compatibility

This roller cage is a direct replacement for the following ZF transmission models: WG92, WG98, WG180, WG200, and WG250 series. It is specifically validated for use in the planetary carrier assembly of these heavy-duty off-highway transmissions. Always verify the cage condition when replacing the 4660301058: HOUSING or the 0631306174: CYLINDRICAL PIN.
