How To Rebuild A Simpson Pressure Washer Pump
Pressure washers are powerful tools that can make cleaning tasks much easier and more efficient. However, over time, the pump of a pressure washer may start to wear out and lose its effectiveness. Instead of buying a new pump, it is often possible to rebuild the existing pump and restore its performance.
Rebuilding a Simpson pressure washer pump requires some basic tools and a good understanding of the pump’s components. The pump consists of various parts, including plungers, pistons, valves, and seals, which all work together to create the high-pressure water flow. By disassembling the pump, inspecting each part, and replacing any worn or damaged components, you can effectively rebuild the pump and extend its lifespan.
Before starting the rebuild process, it is important to gather all the necessary tools and replacement parts. This may include a set of wrenches, pliers, a socket set, and a rebuild kit specific to your Simpson pressure washer model. The rebuild kit usually contains all the required seals, gaskets, and valves to properly rebuild the pump.
To begin the rebuild process, start by disconnecting the pressure washer from its power source and relieving any pressure in the system. Then, remove the pump from the pressure washer frame and carefully disassemble it, following the manufacturer’s instructions. Take note of the order in which the components are removed for easier reassembly.
Once the pump is disassembled, inspect each part for signs of wear, damage, or excessive corrosion. Pay close attention to the seals and valves, as these are often the first components to fail. Replace any worn or damaged parts with the corresponding components from the rebuild kit. It is important to follow the manufacturer’s instructions and use the correct type and size of replacement parts.
After replacing the necessary components, carefully reassemble the pump, ensuring that all parts are properly aligned and tightened. Use a torque wrench to tighten bolts and screws to the specified torque settings. Once the pump is reassembled, reinstall it back onto the pressure washer frame and reconnect all hoses and fittings.
Finally, before using the pressure washer, it is important to prime the pump by filling it with water and purging any air from the system. Follow the manufacturer’s instructions for priming the pump, as this may vary depending on the model.
By rebuilding your Simpson pressure washer pump, you can save money and prolong the life of your pressure washer. Regular maintenance and inspection of the pump can also help prevent major issues and ensure optimal performance. Remember to always use caution and consult the manufacturer’s instructions when working on any machinery.

Inspect and clean the pump components
Before rebuilding the Simpson pressure washer pump, it’s important to thoroughly inspect and clean all of the pump components. This will help ensure optimal performance and longevity of the pump.
1. Disassemble the pump
Start by disconnecting the pressure washer from the power source and relieving any pressure in the system. Then, carefully remove the pump from the pressure washer unit. Remove any screws or bolts securing the pump components together and separate them.
2. Clean the components
Using a cleaning solution and a soft brush, carefully clean each component of the pump. Pay close attention to removing any dirt, debris, or buildup that may have accumulated on the parts. Rinse the components thoroughly with clean water to remove any remaining residue.
Note: Take extra care when cleaning the pump seals and gaskets to avoid damaging them. Use a gentle touch and avoid using abrasive materials or harsh chemicals.
3. Inspect for damage
Inspect each pump component for any signs of damage, such as cracks, wear, or corrosion. Pay close attention to areas where seals and gaskets are located, as they may be susceptible to damage. If any components are damaged, they will need to be replaced before reassembly.
Note: Take note of any seals or gaskets that may need to be replaced during reassembly. It’s a good idea to have replacement seals and gaskets on hand before starting the rebuilding process.
4. Check for clogs
Using a small tool such as a toothpick or a small wire, check for any clogs or obstructions in the pump’s passages and nozzles. Clear any blockages that may be present to ensure proper flow of water through the pump.
By thoroughly inspecting and cleaning the pump components, you can ensure that your Simpson pressure washer pump is in optimal condition before proceeding with the rebuilding process.
Replace damaged or worn-out parts
Over time, the parts of your Simpson pressure washer pump may become damaged or worn out. It’s important to regularly inspect and replace any parts that show signs of wear to maintain the pump’s performance and prolong its lifespan.
Here are some common parts that may need to be replaced:
1. Seals and O-rings
The seals and O-rings in your pressure washer pump help to prevent leaks and maintain pressure. If you notice any signs of leaking, such as water dripping from the pump or low pressure output, it may be time to replace these parts. Make sure to clean the surfaces before installing new seals and O-rings.
2. Valves
The valves in your pump control the flow of water and help to maintain pressure. If you experience a loss of pressure or hear unusual noises coming from the pump, the valves may be damaged or worn out and should be replaced. Properly lubricate the valves before installation to ensure smooth operation.
3. Pistons and seals
The pistons and seals play a crucial role in generating pressure and moving water through the pump. If you notice a decrease in performance or excessive noise during operation, it may be a sign that the pistons or seals are worn out. Replace them to restore the pump’s performance.
When replacing parts, make sure to use genuine Simpson replacement parts or parts that are compatible with your specific model. Follow the manufacturer’s instructions and guidelines for the installation process to ensure proper functioning of the pump.
Regularly inspecting and replacing damaged or worn-out parts will help to keep your Simpson pressure washer pump in optimal condition and extend its lifespan.
Reassemble the pump and test
Once you have cleaned all the components and replaced any damaged parts, it’s time to reassemble the pump. Start by carefully placing the piston back into the pump housing, making sure it fits securely. Next, attach the connecting rod to the piston and tighten the bolts or screws to hold it in place.
After reassembling the piston and connecting rod, it’s important to lubricate them with pump oil to ensure smooth operation. Apply a generous amount of oil to the piston and connecting rod, making sure to distribute it evenly.
Once the piston and connecting rod are properly lubricated, carefully place the pump head back onto the crankcase, aligning the holes with the bolts or screws. Use a socket wrench to tighten the bolts or screws, ensuring a secure fit.
Finally, reconnect any hoses or fittings that were disconnected during the disassembly process. Double-check that all connections are tight and secure.
Once the pump is reassembled, it’s time to test it. Start by connecting the pressure washer to a water source, such as a garden hose. Turn on the water supply and let it run through the pump for a few seconds to prime it.
Next, start the pressure washer according to the manufacturer’s instructions. Listen for any unusual noises or vibrations, as these could indicate a problem with the reassembly. Check for any leaks around the pump or fittings, and if necessary, tighten them further.
If everything looks and sounds good, run the pressure washer for a few minutes to ensure it’s operating smoothly. Pay attention to the pressure and flow rate, making sure they’re at the appropriate levels for your needs. If you notice any issues, make sure to troubleshoot and address them before using the pressure washer for any tasks.
By following these steps and testing the reassembled pump, you can ensure that your Simpson pressure washer is ready to tackle any cleaning tasks with optimal performance.
