You can easily swap the piston in an axial pressure washer pump, but it must be done with care to ensure that the pump functions well once the process is over. Below are instructions to guide you:
- Prioritize safety: Before commencing any form of repairs or maintenance on your pressure washer, turn it off and detach it from power. To release residual pressure in the system squeeze the trigger.
- Approach the pump: There may be a cover or housing protecting the pump; remove it to get into these parts.
- Identify a piston: Look for pistons inside the pump. Visibly, pistons are attached to crankshafts when one opens up the housing of the vessel.
- Remove connecting rod: The connecting rod connects the piston to crankshaft. Delicately separate this part from its corresponding opposite side. Some unscrewing or unbolt might be necessary depending on how water pumps are designed.
- Take out piston: It is easy to slide out piston gently from its cylinder after disconnecting this link between them. Observe if there are any seals or O-rings during removal process which should not be ripped off.
- Clean and examine surfaces : Just eliminate all traces of dirt and other forms of contamination from cylinders and pistons. Turnaround check whether cylinders show visible signs of distress as a result of physical attrition such as abrasive wear? If damaged, replace!
- Put in fresh piston: Then put a thin layer lubrication oil onto new pistons before slowly inserting them into cylinders keeping their rings lined up straight while moving smoothly.
- Reconnect connecting rod again: After disassembling these parts replaced connecting rods connectors have to be tightly fixed using screws or nuts however taking care not to overtighten hence damage occurs
- Assemble back all other units: Once you have positioned every single component at its proper place in relation with others then tighten all bolts accordingly as per manufacturer’s instruction manual.
- Test power washer machine performance : Having reconditioned your machine by fitting a new piston and assembled it thereafter, plug in power washer to its source of energy. It is crucial to test run the pressure washer for brief period checking for leaks or any strange noise due to malfunctioning parts. Confirm that the newly put piston operates efficiently also creating necessary water pressures.
By following these steps, you should be able to successfully replace a piston in an axial pressure washer pump. However, it’s always recommended to consult the user manual or seek professional assistance if you’re unsure or inexperienced with such repairs.
