W-977 Quick Start Guide Transcription:

Welcome to DerekWeaver.com. In this video, we will discuss receiving, unpackaging, and assembling your W-977 wheel balancer.

When your W-977 arrives, it will be packaged in a crate similar to this crate. Prior to signing the delivery receipt, inspect the crate for damage or irregularities and note that on the delivery receipt. Your crate will have an address label with your address. It will have an orange warning label that tells the freight company to handle the crate with caution. You'll have a white warning label that tells you to inspect the crate before signing the delivery receipt and note any damage on the delivery receipt, and a green label that tells the freight company not to stack the crate.

To remove the top of the crate from the skid, loosen the 10 tabs around the bottom of the crate. After the 10 tabs are loosened, you can remove the top of the crate. Now we will remove the top of the crate - you may need assistance for this step.

Remove the remaining packaging material and take inventory of the items in the crate. You should have a small box with the hood part of the hood assembly, a large box, which is an accessory box, and the hood, and, of course, the wheel balancer itself.

You can now unbolt the balancer from the skid. Remove two handles from the accessory box and install them on the left-hand side of the machine to be used as solid lifting points for removing the wheel balancer from the skid.

Now we can remove the wheel balancer from the skid.

We're going to start the assembly by installing the hood. Begin that by removing the four Allen bolts from the back of the machine using an 8-millimeter Allen wrench. Once you've removed the hood bracket from the small box, you can install it on the back of the machine where you remove the four Allen bolts. Once the hood bracket is installed and plug the two wires from the hood switch and the two wires protruding from the back of the machine, really remove the Allen bolt from the hood shaft and remove the protective Styrofoam from the hood switch.

Now we will install the hood on the hood shaft. Continue sliding the rod into the shaft until it's firmly on. Once the hood is fully on the hood shaft, you can rest it on its open stop. Install the Allen bolt back in the hood shaft to keep the hood on. Tighten it with an 8-millimeter Allen wrench and install the hood spring which you'll find in the accessory box.

Now we will install the three remaining accessory handles and the tool holder snaps into place. The final step of the installation is to install the 40-millimeter shaft. You tighten until it's hand tight and then we use an 8-millimeter Allen wrench in the screw hole to cement the shaft.

Now we will define the key function for the W-977:

  • The DYN/STA key allows you to enter the dynamic mode or the static mode.
  • The ALU key allows you to enter one of four standard alternative weight placement modes.
  • The ALU* key allows you to enter machine-defined alternative weight placement, in which case you will use the distance gauge to place your stick-on weights.
  • The matching key allows you to match the heavy side of a wheel to the light side of the tire.
  • The CAR/MOT key allows you to enter the car mode of the motorcycle mode.
  • The weight split key allows you to split weights and hide them behind spokes for a more aesthetically pleasing look.
  • The Millimeter/Inch key allows you to use millimeters or inches.
  • The people key, when pushed briefly, shows you the exact amount of imbalance of a given tire wheel assembly. When held for 6 seconds, it allows you to enter the calibration mode.
  • The Gram/Ounce key allows you to change from ounces to grams.
  • The house key allows you to enter the program mode and allows you to define user settings for one of four users.
  • The DIS plus and minus key allows you to change the distance.
  • The BRE plus and minus key allow you to change the wheel width.
  • The DIA plus and minus key allow you to change the wheel diameter.
  • The stop key stops a spin cycle and the start key starts a spin cycle.

Your W-977 wheel balancer is assembled and ready for use. Prior to balancing your first wheel, we recommend calibrating the machine.

W-977 Wheel Balancer Distance Arm Calibration Transcription:

Hi, and welcome to DerekWeaver.com. In this video, we'll be detailing the calibration of the distance arm on the W-977 wheel balancer.

First step in calibrating the arm is to press the HOME key once. Press the DISTANCE key once and press the HOME key twice. The display will read POS and a position indicator here, rotate it until it's at 110. Press the PEOPLE key and then rotate it until it reads 130. Press the PEOPLE key again. Now it reads CAL DAS. At this point, we'll hit the HOME key once and it will zero the arm at rest, so the arm should be at rest here. Press the HOME key again. Now that reads FAC 150. We will pull the arm out until the gauge reads 150 and press the HOME key.

When we release the arm, it will go into the diameter calibration. Press the HOME key and with the arm located at the stub of the shaft, press the HOME key. Next, we'll bring the arm to the bead seat on the rim, in this case we have a 15-inch wheel we're using for calibration, so we're going to change the diameter to 15 and then press ENTER or the HOME key and that stores the data for our arm. At that point, check the arm. It should read the diameter and the distance correctly on the display. You will need to input the width manually.

That concludes the calibration of the distance arm on the W-977 balancer. Please also watch our video on the calibration of the balancer itself and thank you for choosing DerekWeaver.com.



W-977 Wheel Balancer Calibration Transcription:

Hi, and welcome to DerekWeaver.com. In this video, we're going to detail the calibration of the W-977 balancer. In order to do that, you'll need a 14, 15, or 16-inch wheel in good condition, not necessarily balanced, but in good condition.

First thing we need to do is put the parameters of the wheel in correctly. If you haven't done so already, it would be a good idea to watch the video on the calibration of the distance arm for the W-977. It is an automatic data entry arm, so by pulling the arm out and holding against the bead seat it automatically puts the distance and the diameter of the wheel in for you. The only manual entry you'll have to put in is the width using the rim width calipers.

The next step in the calibration is to press the HOME key. It’ll read “Set Opt.” Next, DISTANCE up, next HOME key twice. Now it reads “position” and it gives you a number indication on the right side of the display. We're going to rotate the tire and wheel assembly till we get to 110. Hit the PEOPLE key and rotate to 120. Hit the PEOPLE key again and this display changes to “Add” “0.00.” We're going to spin the tire wheel assembly with nothing on it simply by lowering the hood. We're going to take our three-and-a-half-ounce calibration weight that was provided with the balancer, line the location up on the right or outer plane directly at 12 o'clock. Paying close attention to that location will help the accuracy of the calibration. Next, we'll spin the balancer. At this point, we'll remove the calibration weight from the right plane, line our location up on the left plane, and hammer the calibration weight precisely at 12 o'clock. Spin the balancer again. It will save the data and the balancer is calibrated.

After calibrating your balancer, it'd be a good idea to balance a tire to verify that the machine is indeed working properly and then imbalance the tire to see whether or not the machine is measuring the imbalance correctly. To do this, we’ll balance the tire.

Once we verified that the tire is balanced, next we'll take a known weight, in this case we're using a two-ounce weight, and we'll just hammer it on our wheel anywhere and spin the machine up. If the machine is working properly, it should read the weight amount within a quarter of an ounce of what you put on and also the location should be correctly at six o'clock. You can verify both planes by then removing the two-ounce weight from the inner plane, hammering it on the outer plane, and doing the same test.

Also line up the location indicators to make sure that your two-ounce weight does indeed show up at 6 o'clock. This concludes the calibration procedure for the Weaver W-977 balancer.
