Pump Oil Change

Everyone associated with servicing of pressure washers needs to know how to change oil on high high pressure pumps. Apart from the fact that the job is very boring, it also leaves the place and the client’s machine in an oily mess. Our purpose is to go through the process of pump oil change with relative ease and tidiness. It must be noted that if the pressure washer oil is warm it will come out much more easily no matter which method is applied. Below are some methods for performing pump oil change:

Hand suction pump:

The hand suction pump is the most suitable device for performing pump oil change if you are working outdoors. It consists of a manual air pump and container to collect the oil. When you start pumping, a vacuum is created inside the container. A tube stretches from the container to the pump crankcase. The tube contains a one-way valve which helps in increasing and maintaining the vacuum.

The above method has many plus points. First of all the oil goes straight into the container. Secondly, it is very easy to manage the air pump. There are two types of hand suctions pumps available in the market for pump oil change: the commercial ready-to-use version Topside Oil Changer. The second is the LiquiVac. Apart from the above two, you can also make use of any other brands available in the market.

Apart form the above mentioned hand suction pumps, you can also make your own suction pump from a garden sprayer. You can adopt the following techniques for making a suction pump form your garden sprayer:

  • Open the air pump of your garden sprayer
  • Reverse the cup washer on the plunger
  • Reverse the flapper valve at the bottom of the cylinder
  • Replace the internal dip tube with a larger tube with one-way valve

When the above things are done properly, the sprayer will start sucking when pumped. If you used a clear tube it will be very useful since you will be able to see the flow of oil from the tube.

Electric suction pump

This pump works on the same principal as the hand suction pump. The simple difference is that it uses electricity in place of manual pumping for producing vacuum. The good news is that you can also construct such a device at your home for free. All you have to do is find a small compressor and a container will a strong lid.

Attach two tubs to the lid of the jar. Attach one end of the tune to the compressor and other to the lid of the container and attach the other tube from the lid of the container to into the drainage pump. The jar must fit properly over the container. The moment you turn on the compressor, the oil will come into the container. You can also make increase the mobility of your device if it is mounted on a trolley or something with small wheels attached to it. You cannot use this device outdoor since it requires electric power.

Draining

It is a very difficult method for performing pump oil change. The process of emptying the pump through drainage will mess up the location and leave the whole place oily and greasy. If you are using this process, you must make some adjustments first. The oil that comes on the pumping platform should be channeled to fill in old bottles or a container. You can also attach a pipe or a hose to the drain outlet in case you do this exercise often. The trick is not to let the drained oil spread all over the place.

Suction Gun

It’s very easy to get hold of a suction gun form the market. All you have to do is to find a pipe and stretch it through to the floor of the crankcase. The pipe should be reasonably thick. Attach this pipe to the suction gun and start performing pump oil change. After draining the oil you have to empty the suction gun. In addition to that, the suction gun needs a fair amount of labor for operating. A suction gun is much more feasible than draining.
