The GRACO 117632 is a square key measuring 3/16 x 1-1/4 inches. It is a mechanical component typically made from steel, designed to fit into keyways of shafts and hubs to prevent relative rotation between connected parts in GRACO equipment such as paint stripers and hydraulic sprayers.

Key Features:

• Square key
• 3/16 x 1-1/4 inches
• Steel (assumed, not explicitly stated in available documentation)
• Compatible with various GRACO equipment models, including LineLazert IV 200HS Airless Paint Striper, LineLazert 130HS Airless Paint Striper, and GH 130, 200, 230 Hydraulic Sprayers
• Precision fit for secure shaft-hub connection
• Simple, reliable mechanical component
• Essential for proper equipment assembly and function

Applications:
Used in GRACO paint stripers and hydraulic sprayers to secure rotating components such as pulleys, gears, or couplings to shafts, ensuring reliable power transmission and equipment operation.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, reliability, and safety in equipment operation.
• Place the key in the keyway opening and tap into place so that the face of the key sits recessed slightly from the face of the hub.
• Ensure the key is fully seated before assembling the hub or pulley onto the shaft.
• Follow torque specifications and assembly instructions in the equipment manual for related hardware.
• Inspect the key and keyway for wear or damage during routine maintenance.
• Replace the key if it shows signs of deformation or excessive wear.
• Keep spare keys on hand for quick replacement if needed.
