Multiquip A400285200 Pulley Washer

The Multiquip A400285200 Pulley Washer is a genuine OEM component designed for GBX series balloon systems and towable towers, including the GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK. As a direct OEM replacement, this washer is sourced from Multiquip and built to the same specifications as the original part. Keeping this hardware in serviceable condition is essential to maintaining correct pulley alignment and drive system integrity across GBX series equipment.

Key Features

• Genuine OEM Specification: — Manufactured to the exact dimensional tolerances required for correct seating and load distribution at the pulley interface.
• Direct Drop-In Replacement: — Engineered to install in the same position as the original hardware, with no modification to mounting points or adjacent components.
• Broad GBX Series Fitment: — Compatible with GBX balloon systems and towable tower models including GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK.
• Drive System Integrity: — A correctly seated pulley washer maintains proper tension and alignment in the drive assembly; a worn or missing washer can cause uneven load transfer and accelerated wear on surrounding components.
• Verified Part Number: — Order with confidence using Multiquip part number A400285200 to ensure you receive the correct hardware for your GBX unit.

A pulley washer sits between the pulley and its mounting surface, distributing clamping load evenly and preventing the fastener from pulling through or damaging the pulley hub. It plays a small but critical role in keeping the pulley seated squarely on its shaft, which in turn keeps belt tension consistent and the drive system running smoothly. When a washer is missing, deformed, or worn thin, it can allow the pulley to shift under load, leading to belt slippage, increased vibration, and premature wear on the pulley and shaft assembly.
