Compatibility
This pump is designed to be compatible with various pressure washer units, including Sears Craftsman models 580.752230 and 020371-0. However, it is crucial to verify compatibility before installation.

- Engine Specifications: The RMV Series pumps are designed with a matching flange for convenient connection to most 3/4" shaft 4-7 HP engines.
- Verification: Please confirm your unit's model, spec, type/code, and serial number in addition to the OEM part number to ensure this is the correct part.
If you are unsure about compatibility, please contact the supplier for assistance.
Setup and Installation
- Prepare the Engine: Ensure the pressure washer engine is turned off, cooled, and disconnected from any power source or fuel supply.
- Remove Old Pump (if applicable): Carefully remove the existing pump from the engine, noting the orientation and connections.
- Mount the New Pump: Align the new RMV25G30D-EZ pump with the engine's 3/4" horizontal shaft. The pump features a 4-bolt pattern for secure attachment. Use the provided bolts and lock washers to fasten the pump to the engine. Ensure bolts are tightened securely but do not overtighten.
- Connect Water Inlet: Connect a standard 3/4" garden hose to the pump's 3/4" GHA inlet. Ensure the connection is tight to prevent leaks.
- Connect High-Pressure Outlet: Attach your high-pressure hose to the pump's 22mm x 14mm outlet. Secure this connection firmly.
