ZF 5838.300.016 CAGE | OEM Genuine Part

Overview

The ZF 5838.300.016 CAGE is a precision-engineered OEM genuine component designed to house and align the planetary gear set within heavy-duty ZF transmissions. This structural carrier ensures correct gear spacing and load distribution under extreme torque conditions found in construction machinery. The SKU 5838.300.016 sits directly inside the transmission housing, where it supports the differential assembly and interacts with rotating clutch packs. Without this cage, the internal gear train cannot maintain its critical clearances, leading to premature wear on adjacent components such as the 5838109007: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Transmission housing vibration at low speeds — A worn cage allows the planetary gears to shift out of alignment, causing noticeable shuddering during loading cycles.
• Metallic grinding noise from the differential area — When the cage fractures or deforms, it contacts the 2095209019: DIFFERENTIAL housing, producing a distinct scraping sound.
• Intermittent gear slipping under load — Loss of cage rigidity permits gear train backlash to exceed tolerances, resulting in momentary power loss when excavating or lifting.
• Oil contamination with metallic debris — Cage wear particles circulate through the transmission, often lodging in the 0631329086: SPRING PIN bores and blocking lubrication passages.

Technical Specifications

Compatibility

This cage is engineered for ZF WG series powershift transmissions commonly used in wheel loaders, dozers, and graders. It directly fits the following models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310

Always verify the cage’s spline count and bolt pattern against your transmission’s planetary carrier before installation. The 5838300682: DIFFERENTIAL AXLE must be inspected for scoring when replacing this cage.
