ZF 0750.115.081 NEEDLE CAGE | OEM Genuine Part

Overview

The ZF 0750.115.081 NEEDLE CAGE is a precision-engineered OEM genuine component designed to support and guide rolling elements within the planetary gear sets of heavy-duty ZF transmissions. This needle cage sits directly between the main shaft and the gear hub, ensuring correct needle roller spacing and reducing frictional heat during high-torque operations in construction machinery. As a critical wear item, the SKU 0750.115.081 maintains axial alignment and load distribution, preventing metal-to-metal contact that can lead to catastrophic gear failure. When replacing this part, it is essential to also inspect the 2094104412 MAIN SHAFT and the 2094304054 MAIN SHAFT for scoring or pitting, as damaged shafts accelerate needle cage degradation.

Symptoms of Failure

• Transmission gear slipping under load: A worn 0750.115.081 needle cage allows needle rollers to skew, causing intermittent torque loss during excavation or grading operations.
• Metallic grinding noise from the gearbox: As the cage breaks down, loose needles create a distinct high-pitched scraping sound, particularly noticeable in lower gears.
• Oil contamination with metallic debris: Flakes of hardened steel from the cage mix with transmission fluid, visible as glitter in oil samples during routine maintenance.
• Hard shifting or gear engagement delay: Misaligned rollers increase rotational resistance, making the 2094106010 SHIFT SYSTEM struggle to synchronize speeds.

Technical Specifications

Compatibility

This needle cage is engineered for ZF heavy-duty powershift transmissions commonly found in wheel loaders, dozers, and excavators. Based on its dimensional code (115mm OD, 81mm ID), the 0750.115.081 is compatible with the following ZF models: WG180, WG200, WG211, and WG310 series. It also fits select variants of the 4WG200 and 6WG310 planetary gear sets. Always verify the cage width against the existing assembly; the 2094206001 GEARSHIFT SHAFT must be free of burrs to ensure proper cage seating.
