Today, we are going to demonstrate how to replace the unloader on your Pw style Pressure Washer pump. The tools you are going to need for this are a flat head screwdriver and a rubber mallet. The first step is to pry off the pin securing the unloader to the manifold using the flat head screwdriver. Next, you will want to insert the screwdriver between the coils of the unloader and use the manifold as a fulcrum to pop the unloader free. Before installing the new unloader, make sure that the unloader stem moves freely back and forth and also apply a layer of grease to prevent damage to the orings when inserting it into the manifold. When installing the unloader, you will want the outer flange to be inserted past the groove on the manifold in order to secure it with the pin. If the unloader is sitting on the groove, then the pin cannot be inserted. If you cannot get the unloader past the groove, use the rubber mallet to tap the unloader into place. Be careful not to use too much force though because you can damage it if you do. The last step in this procedure is to insert the pin into the manifold to secure the unloader into place. There’s no need to adjust the unloader because it comes preset.
