The GRACO 15G559 is a lower housing component designed for hydraulic motors used in GRACO sprayer and pumping systems. It is typically constructed from robust materials such as carbon steel or similar alloys to withstand the rigors of hydraulic operation. Its primary function is to encase and protect the lower section of the hydraulic motor assembly, ensuring reliable performance and longevity within GRACO equipment.

Key Features:

• Lower housing for hydraulic motor
• Carbon steel or similar alloy (inferred from typical GRACO hydraulic motor housings)
• Compatible with GRACO GH Series Big Rig Sprayers, RoadLazer HPS 135 and HPS 180 Hydraulic Pumping Systems, and other models where 15G559 is listed as a replacement part
• Robust construction for durability
• Designed for easy integration with GRACO hydraulic motor assemblies
• Supports reliable operation in demanding environments

Applications:
Used in GRACO hydraulic sprayer and pumping systems, including GH Series Big Rig Sprayers and RoadLazer HPS 135 and HPS 180 systems, where it serves as a critical component for motor protection and system integrity.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and longevity of the equipment, reducing the risk of premature failure or system downtime.
• Ensure the system is depressurized before installation
• Follow GRACO equipment manual instructions for proper assembly and torque specifications
• Inspect the housing and mating surfaces for damage or contamination before installation
• Use appropriate tools and safety equipment during installation
• Regularly inspect the housing for signs of wear, corrosion, or leaks
• Replace the housing if any damage is detected to prevent motor failure
• Keep mating surfaces clean and free of debris
