How Ultrasonic Parts Cleaners Work on your Harley-Davidson Dyna Motorcycle Carburetor

Ultrasonic cleaning systems are used in a wide range of applications to remove virtually any soil or contamination by using the power of cavitation action. This is the term used to describe the implosion of billions of minute bubbles contacting carb parts being cleaned. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

When the bubbles implode contaminants are quickly and safely blasted away from wetted surfaces without damaging delicate carb parts. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach by hand scrubbing using conventional parts washers or aerosol sprays The ultrasonic aqueous parts washer will complete the job in less than an hour, meanwhile freeing you up to attend to other tasks. And it will do it in an environmentally friendly manner because the ultrasonic carburetor cleaning formula is a biodegradable concentrate that minimizes disposal problems.

How to Select and Set Up your Harley-Davidson Dyna Motorcycle Ultrasonic Carb Cleaner

Ultrasonic carb cleaners come in a variety of sizes from bench top units to a floor-mounted industrial ultrasonic cleaning machine, so you can select any size you need. Our most popular 1½ gallon models for cleaning one carburetor at a time are the TOV150-6L and EH150EL. Select an ultrasonic carb cleaner equipped with a heater to improve the ultrasonic carburetor cleaning process.

Whatever the model and size ultrasonic carb cleaner you use there are steps to take before cleaning begins.

  1. Fill the ultrasonic carb cleaner tank to the fill line (or approximately 2/3 full) with ultrasonic cleaner solution diluted per manufacturer’s recommendations.
  2. Turn on the ultrasonic cleaner, set the heater to approximately 70°C, and operate the ultrasound for about 30 minutes to drive off cavitation inhibiting entrained air. Degassing is complete when bubbles stop coming to the surface and must be performed every time the tank is filled with fresh cleaning solution.

How to Remove, Clean and Reinstall your Harley-Davidson Dyna Motorcycle Carburetor

Step 1: Removing the Carburetor

The first step is to turn the fuel petcock of your Harley-Davidson Dyna motorcycle to its “OFF” position. Then, take the air cleaner cover off by loosening the screws securing it. Don’t forget to remove the air filter, and air cleaner backing plate as well. You should be able to see your carb already. Next, you will have to loosen the adjustment on both the throttle and idle cables.

You will then have to loosen the nut on the enricher cable. Take the nut by allowing it to come out of its bracket, saving both so they don’t get lost. Disconnect the fuel line and the vacuum line for the V.O.E.S. or the Vacuum Operated Electrical Switch. The petcock must also be disconnected as well. To remove your Harley Dyna carb, rock it side to side. Pull it out of your Dyna carburetor intake seal making sure to guide the enricher cable out.

You now hold in your hand, your Harley-Davidson Dyna carburetor.

Congratulations! You have successfully removed your Harley Dyna carb from your motorcycle! You may now proceed with the next step.

Step 2: Cleaning the Carburetor

Although you can clean your carburetor without any disassembly you will achieve the most thorough cleaning with partial disassembly to allow the solution into the float chamber. Remember that only surfaces that are wetted by the cleaning solution will be cleaned. Fine mesh baskets can be used to hold very small parts.

Set the thermostat to 70°C. While the solution is heating, place your carburetor parts in the basket taking care that they do not touch each other. Once the operating temperature is reached lower the basket into the cleaning solution and set the timer for 40 minutes. Cleaning time depends on the condition of the carburetor and may have to be adjusted, depending on the type of iUltrasonic used.

At the end of the cycle remove the components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Then rinse them in fresh water to remove all traces of the cleaning solution and allow them to dry.

Safety note: DO NOT reach into an operating ultrasonic bath. Instead remove the basket if you want to inspect or rearrange the parts.

Step 3: Reinstalling the Carburetor

When replacing your carburetor, it is always a good idea to use a new carb intake seal to prevent vacuum leaks.

To start off, return your Harley Dyna carb to its original position. Ensure that the enricher cable is inside the carburetor intake seal where it is supposed to be. Once your Harley Davidson Dyna carb is secure, the petcock may now be connected. Connect the fuel line and vacuum line for the V.O.E.S. Return the nut to its bracket and tighten it back on the enricher cable.

After the nut is tightened back on, tighten the adjustment on both the throttle and idle cables. Return the air cleaner backing plate first. Return the air filter as well. Put the air cleaner cover back on and tighten the screws securing it. Make sure your fuel petcock is in the “ON” position, before you start your engine.

Admire the piece of work you just put back together.

Voila! Start the engine, and your Harley-Davidson Dyna Motorcycle should be good to go.

More Operating Tips

Oils that rise to the surface of the bath should be skimmed off and disposed of properly. When the solution becomes discolored or cleaning time takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank. Clean the ultrasonic washing machines using a cleaning process recommended by the manufacturer.
