The Multiquip 969340 Key 3/8 x 1.375 is a genuine OEM drive key designed for SP4 flat saws and SP6457 pavement saws. Sourced directly from Multiquip, this replacement key matches the original component specification, ensuring a correct and secure fit within the drivetrain assembly. It is a direct fit for SP4 and SP6457 series machines, eliminating guesswork when ordering service parts. DHS Equipment stocks this OEM component so you can get your saw back to cutting without delay.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's exact dimensional tolerances for a 3/8 x 1.375 keyway slot, ensuring correct torque transfer without slippage.
- Direct Drivetrain Fit: — Drops directly into the existing keyway groove on SP4 and SP6457 saw assemblies with no machining or modification to the shaft or hub.
- Confirmed Fitment: — Verified for SP4 flat saws and SP6457 pavement saws, so you can order with confidence knowing this is the correct part for your machine.
- Maintains Positive Power Transfer: — A correctly seated drive key locks the blade arbor or pulley to the shaft, preserving full cutting power and smooth blade engagement.
- Operational Safety: — A worn or sheared key can cause a blade arbor or drive component to spin free on the shaft — replacing this key promptly restores secure mechanical coupling and safe saw operation.
A drive key is a small but critical component that sits in a milled slot between a rotating shaft and a hub, pulley, or arbor, locking them together so power transfers cleanly from the engine to the cutting blade. Without a properly seated key, the mating component can slip or spin independently on the shaft, resulting in lost cutting power, uneven blade speed, or complete drive failure. When a key shears or wears to the point it no longer fills the keyway, it must be replaced before the saw is returned to service.
