    Certain parts of installing the Balancer are difficult for just one person. BendPak CAUTION Ranger strongly recommends having two or more persons work together to install the Balancer. If you have to use an extension cord, make sure its current rating is equal to or greater than that of the equipment being used.
  • Page 12 Finding a Location Keep in mind the following when deciding on a location: • Power source. The Balancer needs to be near an appropriate power source. • Floor. The Balancer is best used on a flat, concrete floor. If the floor is unstable or not flat, the Balancer will not work correctly;...

  • Page 16 6. Locate the Hood Mount Arm and the Hood. 7. Starting with the bottom of the Hood Mount Arm, slip the hole at the bottom over the Shaft on the left side of the Hood Mount Box. The Shaft is shown in the drawing on the previous page.
  • Page 17 Installing the Shaft The Shaft holds the Wheels you are balancing. BendPak Ranger recommends having rags nearby; the Shaft comes greased to protect it during transport. It’s not ‘if’ you are going to get grease on you, but ‘when’. To install the Shaft: 1.
  • Page 18 3/8 in. diameter Anchor Bolt, for example, use a 3/8 in. diameter drill bit. 3. Vacuum each hole clean. BendPak Ranger recommends using a vacuum to get the hole very clean. Do not ream the hole. Do not make the hole any wider than the drill bit made it.
  • Page 19 Even using a hammer or mallet, the Anchor Bolt should only go into the hole part of the way; this is normal. If the Anchor Bolt goes all the way in with little or no resistance, the hole is too wide. Once past the hole in the Base Plate, the Anchor Bolt eventually stops going down into the hole as the Expansion Sleeve contacts the sides of the hole;...
  • Page 20 Connecting to Power The Wheel Balancer motor comes configured to use a 220 VAC power source. It can be changed to use a 110 VAC power source, if desired. ⚠ CAUTION The setting of the Voltage Selector Switch on the back of the Balancer must match the power source.
  • Page 21 • Use a dedicated breaker for the Balancer. • Electrical codes may require direct connection to the facility’s power system (sometimes called “hard-wiring”) when the Balancer is bolted to the floor.

  • Page 24 The Control Panel The Control Panel lets you enter data for the Wheel being balanced and displays information. The parts of the Control Panel include: • Inner Window. During the Measurements phase—before spinning the Wheel—this Window indicates which measurement needs to be entered. During the Weights phase—after spinning the Wheel—it shows the weight that needs to be added to the inner side of the Wheel, if any.
  • Page 25 • Distance, Width, and Diameter diagrams. Located just above the Plus and Minus buttons, they are visual representations of how you measure the Wheel to get the necessary information: – Distance. Distance from the side of the Balancer to the Inner Edge of the Wheel. –...
  • Page 26 About Measurements In order to balance a Wheel, the Balancer must know three pieces of information about the Wheel. You must gather these measurements and enter them manually for every Wheel you balance. The three measurements are: • Distance. The distance from the side of the Balancer to the Inner Edge of the Wheel. Measured by the Inner Arm.
  • Page 27 Mounting a Wheel When you want to balance a Wheel, the first step is to mount it on the Shaft. Important: All Wheels should be mounted so that the inside (the side of the Wheel that goes closest to the Vehicle) goes on the Shaft first. There are three ways to mount a Wheel onto the Shaft: •...
  • Page 28 • Dual Cone-Mounting. Generally used only for some aftermarket or OEM performance Wheels that have a center hole that is deep enough to allow the use of two cones on the Shaft. The Spring goes on first, then an appropriately sized Cone, the Wheel, a second appropriately sized Cone, and finally the Quick Nut.
  • Page 29 Dynamic Balancing Dynamic Balancing balances a Wheel at the Inner and Outer Edges. It is generally used for steel or some standard OE alloy Wheels. If weight is needed, Clip-On Weights are lightly hammered onto the Inner and Outer Edges. Note: In the following procedure, all of the examples use ounces and inches.
  • Page 30 9. Pull out the Inner Arm and place it against the Inner Edge. This tells the Balancer the distance from the edge of the Balancer to the edge of the Wheel being balanced. 10. On the Inner Arm Ruler, note the distance from the Balancer to the Inner Edge; 8.5 in. the drawing above.
  • Page 31 When the Diameter value is correct, you are done inputting measurements. 17. Lower the Hood; the Wheel spins briefly. 18. When the Wheel stops, lift the Hood. 19. Check the value on the Inner Window. – If the value is 00, you do not need to add Weight to the Inner Edge of the Wheel. –...
  • Page 32 Static Balancing Static Balancing typically for older steel Wheels where the customer wants the weights to be not visible from the outer side of the rim. Also for wheels under 4 inches wide (too narrow to span weights for a proper dynamic balance) and most motorcycle Wheels.
  • Page 33 The value in the Outer Window changes as you press the + and – buttons under Width. 14. When the Width value is correct, use the Calipers to measure the diameter of the Rim or read the diameter off the Sidewall of the Tire. 15.
  • Page 34 Aluminum Alloy Balancing ALU Modes are for balancing Aluminum Alloy Wheels using Adhesive and/or Clip-On Weight. The Balancer supports three ALU Modes: • ALU 1. If the Wheel is out of balance, Weight goes on the Inner Plane and/or the Outer Plane. •...
  • Page 35 This tells the Balancer the distance from the edge of the Balancer to the edge of the Wheel being balanced. 9. On the Inner Arm Ruler, note the distance from the Balancer to the Inner Edge. 10. Return the Inner Arm to its normal location. 11.
  • Page 36 22. Pull the backing off the Adhesive Weights, then add the Weight at Top Dead Center on the Wheel (12 o’clock high) on the Inner Plane. If you are adding Adhesive Weight with multiple sections, center them on Top Dead Center. 23.
  • Page 37 Switching Between Ounces and Grams The display on the Inner and Outer Windows for how much weight is needed to balance a Wheel can show values in Ounces or Grams. The default is Ounces. To switch from the current setting to the other setting: 1.
  • Page 38 Switching Inches and Millimeters for Diameter When you are entering measurements for a Wheel, you can have the values for Wheel Diameter display in either Inches or Millimeters. The default is Inches. To switch from Inches and Millimeters for Wheel Width measurements: 1.
