⚙️ Rear Gear Case Breather Hose · Rear Axle Vent Hose · OEM Spec

📋 Product Overview

This is a CFMoto OEM-spec Rear Gear Case Breather Hose, part number 9AYV-330001-8500, sold as a single unit. This breather hose is an essential component of the rear axle (rear gear case) ventilation system, installed on the vent valve port of the rear gear case housing. It equalizes internal and external air pressure to prevent excessive pressure buildup or vacuum due to temperature changes, while allowing air exchange but blocking dust, moisture, and contaminants from entering the rear axle — protecting the gear oil and drivetrain components.

Over time, the original breather hose may fail due to aging, hardening, cracking, or clogging, leading to abnormal internal pressure, seal leakage, or gear oil emulsification. Replacing with an OEM-spec breather hose is essential to restore rear axle ventilation system function and ensure rear axle reliability.

✅ OEM Quality Assurance: Manufactured strictly to CFMoto original technical standards. Made from premium oil-resistant, aging-resistant rubber, with hose diameter and length identical to the genuine part, ensuring a perfect replacement and reliable venting function.
