It’s that time of year for your annual maintenance. First I’ll explain how the transmission works and the important job the oil plays. Then I’ll explain How to change the oil.
Another important task for your annual maintenance is performing the winterization of the unit. Here is a link to this article on how to perform this job here: How to Winterize your Pressure Washer
Here are the tools you will need to perform this job: 13mm socket, drain pan, funnel, measuring cup, blocks
The function of the oil
The transmission is located between the pump and the motor. The transmission houses the wobble plate and plungers. These parts convert the rotational force of the motor to a pumping motion with the plungers.
This is where the oil is housed. The main job of the oil is to reduce friction. The metal-on-metal contact creates friction and heat between the wobble plate and plungers. The oil acts as a lubricant allowing the parts to move smoothly and reduce wear.
The oil also keeps the transmission cool while running. There is a lot of friction and results in a lot of heat. The heat is transferred into the oil. The oil in turn gets cooled by the fins on the outside of the unit.
Here are the tools you will need for this task: 13mm wrench, funnel, drain pan, measuring cup
How to Change the Oil
The first step is to set the Kranzle on blocks so you can slide a drain pan underneath the drain plug. The next step is to use the 13mm wrench and unscrew the drain plug. It should only take a minute or two to let the oil drain out. Next, screw the drain plug back on.
To fill the unit with oil, you will need a measuring cup to measure .25 liters. You can use either Kranzle-specific oil or any SAE 15W-40 oil fully synthetic from your local auto parts store.
Once the oil is measured out, use the funnel to pour it into the hole for the dipstick. The last step is to take the used oil to your local auto parts store to properly recycle it.
Now your Kranzle has fresh oil for the year. Be sure and check out our support article on how to keep the pump internals lubricated: How to Winterize your Pressure Washer. If you have any more questions, reach out to Support@obsessedgrage.com
