Zhongtong Bus Idler Wheels 9405-01397 Corrosion Resistant & High Strength Alloy Steel

This high-quality idler wheel with part number 9405-01397 is specifically engineered for Zhongtong and King Long buses, including coach, city bus, and passenger bus models. As a critical component in the transmission system, it ensures reliable direction changes for timing belts, chains, or belt drive systems while maintaining stable tension and smooth power transmission.

• Perfect Compatibility - Designed specifically for Zhongtong and King Long bus transmission systems
• OE-Grade Durability - Manufactured to original equipment standards for long service life
• Stable Performance - Reduces vibration and noise while preventing belt/chain deviation
• Wear & Corrosion Resistance - Withstands harsh operating environments including high temperatures, dust, and oil contamination
• Strong Load-Bearing Capacity - Engineered for reliable performance under heavy loads

Manufactured using high-strength alloy steel for the wheel body and high-performance sealed ball bearings with ACM or FPM fluorine rubber sealing rings. Precision forging, quenching, turning, and polishing processes ensure compact structure, excellent wear resistance, and reliable performance in demanding bus operating conditions.

Direct replacement installation requires no modifications. Simply align the idler wheel with the mounting shaft, secure with locking bolts, and apply high-temperature lubricating grease if needed. Ensure proper installation direction matches the original vehicle configuration and verify smooth rotation without binding or abnormal noise.

Each unit undergoes comprehensive factory testing including dimensional accuracy, hardness, rotation performance, wear resistance, high-temperature resistance, and sealing performance tests. Complies with national safety standards for automotive transmission accessories and original equipment requirements.
