Welcome to DerekWeaver.com. In this video we will demonstrate the assembly and use of the W-MJ-II Motorcycle Wheel Balancer Adapter Kit using the W-957 Wheel Balancer.
When you receive your W-MJ-II, it will come packaged in a box similar to this box. When you open the box, you'll find the W-MJ-II User Manual. There will be a small package that contains the distance gauge extension, the W-MJ-II shaft, cone and spacer assortment, your two Allen bolts for the wheel clamp, and last, the wheel clamp.
To install the W-MJ-II you will need a 15-millimeter combination wrench and a 6-millimeter Allen head. Install the wheel clamp by placing it over the stub shaft. Align the holes in the flange with the threaded holes in the wheel clamp. Insert your Allen head cap screws. You will have to tighten the cap screws alternately until the wheel clamp is flush with the flange.
Now we will demonstrate the mounting procedure using the W-MJ-II Motorcycle Wheel Balancer Adapter Kit on the W-957 Wheel Balancer. It is important not to damage the industry standard 14-millimeter shaft on the MJ-II during the mounting procedure. Start by expanding the wheel clamp to its locked position. Choose the correct cone size and verify the cone fits in the ID of the wheel.
Place the first cone on the shaft. Now we will place the wheel on the shaft. Note that this wheel does not have a drive mechanism or a caliper. In most instances, the wheel can be balanced with those components installed. Carefully slide the wheel onto the shaft. Place your second cone on the shaft, and then place spacers on the shaft to take up the additional space. Place the [inaudible 2:28] screw on the end and tighten it until it's snug. Release the lock to engage the clamp. Release the second lock to engage the clamp.
Now we will demonstrate the balancing procedure. To begin the balancing procedure we must place the wheel balancer in motorcycle mode and static balance mode. Now we will enter the three dimensions: distance, diameter, and width.
Now we will obtain and enter the distance dimension for this wheel. Pull the distance gauge out and touch the pointer to the bead of the wheel. Note the dimension. On this wheel it's 88 millimeters. To enter the distance dimension, use the DIS plus or minus. Change it until the distance matches what was on your distance gauge, 88 millimeters.
To obtain the wheel width, place the width gauge on the bead of the wheel. Note the dimension is 5 inches. Use the BR plus or BR minus button to adjust the width dimension to 5 inches as shown here in the outer window.
The final dimension is the diameter which can be found stamped on the sidewall of the tire; 17 inches. Enter the diameter using the DIA plus or DIA minus key - 17 inches for this wheel.
Now that we have properly mounted the wheel and entered the three dimensions - distance, width, and diameter - shut the hood to begin the spin cycle. Once the machine brakes, the spin cycle is complete. Raise the hood and rotate the wheel until all of the LED lights to the left of the outer window are lit.
At this point you want to place a half-ounce of weight somewhere across the width of the wheel. Prior to affixing stick-on weights, clean the wheel to ensure the weights adhere. After you have properly positioned your wheel, you can add your stick-on weight at the 12:00 position as seen here. Because this wheel assembly has been balanced in static mode, the weight can positioned anywhere across the width of the wheel while maintaining the 12:00 position.
After the weight has been applied, we verify the wheel is balanced by running the wheel through another spin cycle. To initiate the spin cycle, simply shut the hood. The wheel will spin. After the wheel has braked and stopped, we see that the machine no longer requires weight which tells us this wheel is balanced.
The optional MJ-I has a 19 millimeter shaft and is one inch longer than the MJ-II. The MJ-I is recommended for tire sizes larger than 180 millimeters, as well as heavier wheel tire assemblies. The MJ-I comes with a 19 millimeter shaft, one set of cones that will do up to a two-inch axle, spacers, and a shaft extension.
