How Ultrasonic Parts Cleaners Work on your Yamaha Grizzly 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 cleaner from iUltrasonic 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 Grizzly 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.

Whether you own a benchtop ultrasonic cleaner or a larger ultrasonic model,there are important 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 digital ultrasonic cleaner and set the heater to approximately 70°C. 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 Yamaha Grizzly ATV Carburetor

Step 1: Removing the Carburetor

First, you have to get the seat off by pulling the seat lock lever upward and pulling the seat up at the rear. Remove the four screws that hold the fuel tank cover. Take the fuel cap off first then completely remove the fuel tank cover. There are fuel tank bolts located at the back, front left and front right. You will have to remove these. The bolts located at the left and right can be easily removed from under the fender. Remove the fuel line from the tank and the fuel tank should come right off.

Once the tank is off, there should be two allen bolts connecting the intake boot which have to be removed. Using a screwdriver, loosen the screws and remove the black cover from the side of your Yamaha Grizzly ATV carb. To detach the throttle cable from the carburetor, bring the lever up and the cable through the gap. Pull this out gently and grab the tiny washer so that you won’t lose it.

Remove the nut securing the back of the carb to the whole assembly. The fuel hose must also be disconnected from its connector. Using a screwdriver, remove the screw on top of the intake boot air filter. Pull your Yamaha Grizzly ATV carburetor to get the studs out of the intake manifold. The carb should come off easily with just a few pulls and turns.

Once your Yamaha Grizzly ATV carburetor is off, use a screwdriver to remove the screw holding the throttle bracket on the carb. Pull the throttle cable gently and it should slide right out.

You now hold in your hand, your Yamaha Grizzly carb.

Congratulations! You have successfully removed your Yamaha Grizzly carburetor from your ATV! 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.

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

To reinstall the Yamaha Grizzly ATV carb, firstly, return the throttle cable and slide the needle back inside making sure that the throttle needle and spring will not budge. Screw the throttle bracket back on the carburetor. Return the carb to its original spokes in the intake manifold. Push it in place until it stays firm and secure.

Screw the top of the intake boot air filter back on and return the fuel hose to its connector. Secure your Yamaha Grizzly ATV carb to the assembly by securing the nut found at the back of the carb. Attach the throttle cable back into the carburetor by bringing the lever up and inserting the cable through the gap. The washer that you removed should be placed, just as you found it, inside as well.

Return the black cover of the carb and screw it on. Secure the two allen bolts connecting the intake boot. Place the tank in its original position and connect the fuel line back to the tank. Next, secure the bolts located at the back, front, left and front right of the tank. The bolts located at the left and right can be easily removed from under the fender.

Unscrew the fuel cap off, return the tank cover, and then close the opening with the fuel cap again.

Secure the four screws that will hold the fuel tank cover back on. Put the seat back on your ATV by pulling the seat lock lever upward and pushing the seat until it locks in place.

Admire the piece of work you just put back together.

Voila! Start the engine, and your Yamaha Grizzly ATV 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 tank using a cleaning process recommended by the manufacturer.
