What is the Graco 17P984 Coupling, Motor?
The Graco 17P984 Coupling, Motor is a genuine OEM mechanical connector designed to link the electric motor shaft to the pump drive system in Graco airless spray equipment. It plays a critical role in ensuring smooth torque transfer, reducing vibration, and maintaining proper alignment between the motor and fluid pump assembly.
This small but essential component is part of Graco’s internal drive system and is typically used during motor servicing, rebuilds, or when replacing worn drivetrain components. A failing or worn coupling can lead to reduced spraying performance, irregular pump operation, or complete loss of pressure transfer between motor and pump.
Manufactured to OEM specifications, the 17P984 coupling ensures durability under high-load operation, making it suitable for professional-grade spraying applications where consistent motor-to-pump synchronization is required.
Key Function in the System
- Connects motor shaft to pump drive mechanism
- Ensures efficient torque transfer without slippage
- Reduces vibration and mechanical stress on components
- Maintains alignment for stable spray pressure output
