What is the Graco 24H749 Kit, Motor, Pilot Valve?
The Graco 24H749 Kit, Motor, Pilot Valve is an OEM replacement maintenance kit designed specifically for Graco air-powered lubrication and transfer pump motors. It contains a pair of precision-engineered pilot valves that control the air distribution inside the pump’s air motor system.
Pilot valves are critical components in pneumatic pump operation. They regulate airflow that drives the reciprocating motion of the air motor. When these valves wear out, the pump may experience inconsistent cycling, reduced pressure performance, or complete operational failure. Replacing them with the 24H749 kit restores stable air motor function and ensures reliable system performance.
This kit is strictly a pilot valve replacement solution and does not include air valve seals or full air motor rebuild components, making it ideal for targeted maintenance rather than full system overhaul.
Key Function
- Controls air distribution inside Graco pneumatic air motors
- Ensures smooth reciprocating motion of pump piston systems
- Restores performance in worn or failing pilot valve assemblies
- Prevents erratic cycling and loss of pumping efficiency
Compatibility Insight
Based on technical documentation and OEM service references, the 24H749 pilot valve kit is used in Graco air motor systems found in lubrication and grease transfer pumps, especially within the Graco LD series and related industrial pneumatic pump platforms. It is commonly installed in models such as 3A1495C and 3A1496B, where pilot valves are required for air motor switching functionality.
