How Ultrasonic Parts Cleaners Work on your Yamaha Raptor ATV Carburetor

Ultrasonic cleaners 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 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 Yamaha Raptor ATV 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 iUltrasonic, 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.

Step 1: Removing the Carburetor

Firstly, take off both the air filter housing and the air filter as well. Using a screwdriver, loosen the two screws to get access to the fuel tank.

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.

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

Return the Yamaha Raptor ATV carb to its original position by adjusting the air intake tubes and tightening the four screws so that they stay in place. Insert the throttle cable with the cable holder into the carburetor. To do this, rotate the when clockwise and fit the cable holder inside. Use needle nose pliers to make things easier. Be sure that it will not budge once you close everything up.

Return the fuel tank by attaching the three bolts back on the assembly. You will then have to connect the fuel line. Use needle nose pliers to help you with this process. After this is done, tighten the screws in front of the radiator as well as the screws to hold the tank together. Return the fuel tank cover.

Screw the front fender back on. Return the ATV lights. Fix the front panel by securing the two allen bolts once more. Lastly, return the air filter housing and the air filter to the ATV.

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 tank using a cleaning process recommended by the manufacturer.
