The Multiquip A400285400 Pulley Spring is a genuine OEM component designed for GBX series balloon systems and towable towers, including GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK models. As a direct OEM replacement, this spring is sourced from Multiquip and manufactured to the same specification as the original part installed at the factory. Keeping the correct pulley spring in service ensures consistent tension and reliable drive operation across GBX balloon lighting systems. DHS Equipment carries this part in stock to support fast, accurate repairs on your Multiquip equipment.
Key Features
- Genuine OEM Spring Tension Spec — manufactured to the exact load and travel rating of the original, ensuring the pulley maintains correct tension throughout its range of motion.
- Direct Drop-In Replacement — engineered to seat and anchor the same way as the factory part, with no reworking of the pulley assembly required.
- Broad GBX Series Fitment — confirmed for GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK balloon systems and towable towers.
- Maintains Drive System Integrity — a correctly tensioned pulley spring keeps the drive mechanism operating smoothly; a worn or broken spring leads to slack, slippage, or complete loss of pulley function.
- Verified Multiquip OEM Part — sold as a genuine Multiquip component under part number A400285400, so you can order with confidence that fitment and quality are correct.
A pulley spring provides the constant return tension needed to keep a drive belt or pulley mechanism properly loaded during operation. Without the correct spring tension, the pulley cannot maintain consistent contact with the belt or drive element, which can cause erratic operation, premature wear on surrounding components, or a complete loss of drive function. Replacing a fatigued or broken pulley spring restores the designed tension balance and protects the rest of the drive assembly from secondary damage.
