The Multiquip APRD3139 Key is a genuine OEM component designed for AP6 and AP8 series water pumps. As a direct OEM replacement, this key is manufactured to the same specifications as the original, ensuring a correct fit within the drivetrain assembly. DHS Equipment supplies this part direct, so you can be confident you are ordering the exact component your pump requires.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the correct dimensional tolerances for proper shaft-to-hub engagement without slippage.
- Direct Drop-In Fit — Designed to seat precisely into the keyway on AP6 and AP8 pump shafts, requiring no modification to the shaft, hub, or housing.
- Confirmed Fitment — Verified compatible with Multiquip AP6 and AP8 water pumps; always cross-reference your part number before ordering.
- Torque Transfer Integrity — A correctly fitted key locks the impeller or pulley to the shaft so rotational power is transferred efficiently — a worn or missing key causes slippage, output loss, and accelerated component wear.
- Cost-Effective Repair Component — Replacing a failed key early prevents secondary damage to the shaft and hub, keeping repair costs low and the pump back in service quickly.
A key is a small but critical drivetrain component that locks a rotating part — such as an impeller, pulley, or coupling — to a shaft so both turn together as a single unit. It fits into matching slots called keyways machined into both the shaft and the mating component. When the key shears, wears, or goes missing, the shaft spins independently of the driven component, resulting in complete loss of pump output and potential damage to surrounding hardware. Replacing the key promptly with the correct OEM part restores full power transmission and prevents costly downstream failures.
