ZF 5838.300.672 AXLE FLARED TUBE | OEM Genuine Part

Overview

The ZF 5838.300.672 Axle Flared Tube is a precision-engineered hydraulic conduit designed to route pressurized transmission fluid within the final drive assembly of heavy-duty construction machinery. This OEM genuine part, identified by SKU 5838.300.672, functions as a critical connection between the differential housing and the axle shaft, ensuring consistent lubrication and cooling of planetary gears. Constructed from high-tensile steel with a flared end fitting, it withstands extreme pressure fluctuations and thermal cycling common in excavators and wheel loaders. When installed alongside a 5838109007: DIFFERENTIAL, this tube maintains hydraulic integrity for the entire drivetrain system.

Symptoms of Failure

• Hydraulic fluid seepage at axle flange connection – Visible oil residue around the tube end indicates a compromised flare seal, often leading to gradual pressure loss and transmission overheating.
• Intermittent gear engagement hesitation – A cracked or corroded tube restricts fluid flow, causing delayed clutch pack actuation and rough shifting during load cycles.
• Metallic debris in transmission oil – Internal tube wall erosion from cavitation introduces steel particles into the system, accelerating wear on the 0750117075: TAPER ROLLER BEARING and adjacent components.
• Audible whining from final drive – Insufficient lubrication due to tube blockage creates metal-on-metal contact, producing a high-pitched noise that intensifies under load.

Technical Specifications

Compatibility

This flared tube is engineered for ZF powershift transmissions commonly deployed in construction equipment. It is directly compatible with the following models: WG180, WG200, WG211, and WG250 series. The part also integrates with the 2095209019: DIFFERENTIAL assembly in WG200 variants and requires a 0631329086: SPRING PIN for secure flange retention during high-vibration operation.
