The Multiquip 28452-001 Square Key is a genuine OEM component designed for GA9.7HE gasoline-powered generators and AR13HA, AR13HAR, AR13HC, and AR13H asphalt ride-on rollers. As a direct OEM replacement, this square key meets the original engineering specifications set by Multiquip, ensuring proper shaft-to-component engagement right out of the box. Sourced directly through authorized distribution, part number 28452-001 is the correct replacement when the original key is worn, sheared, or lost during service.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, delivering the same shear strength and load tolerance as the factory-installed key.
- Direct Shaft Fit — Designed to seat flush in the keyway with no filing or shimming, allowing proper torque transfer between the shaft and mating component upon reinstallation.
- Broad Equipment Compatibility — Fits GA9.7HE gasoline-powered generators and AR13HA, AR13HAR, AR13HC, and AR13H asphalt ride-on rollers under the Multiquip product family.
- Torque Transfer Integrity — A correctly fitted square key locks rotating components to the shaft, preventing slippage that would otherwise cause accelerated wear on both the shaft and the mating hub.
- Critical Drivetrain Safety — A sheared or missing key can cause sudden loss of drive engagement on rollers and generators; replacing with the correct OEM part restores safe, predictable power transfer.
A square key is a small but essential drivetrain component that locks a rotating part — such as a pulley, sprocket, or coupling — to a shaft, ensuring both turn together as a single unit. It sits in matching keyways cut into both the shaft and the hub, transmitting torque without relying on friction alone. When a key shears or wears, the connected component can spin freely on the shaft, causing loss of drive, accelerated shaft damage, and potential equipment failure — making timely replacement with the correct part critical to keeping the machine in service.
