Coats ProBalance E900 Diagnostic Wheel Balancer

The Coats ProBalance E900 Diagnostic Wheel Balancer combines advanced wheel balancing with ride-quality diagnostics to help professional shops identify and correct vibration problems that conventional balancing alone may not solve. Designed for high-volume tire shops, dealerships, and automotive service facilities, the E900 combines Coats ProBalance Technology®, ProMatch™ diagnostics, Direct Drive technology, 3D automatic data entry, and an intuitive touchscreen interface in one premium wheel service system.

Unlike a conventional wheel balancer that primarily identifies weight imbalance, the E900 uses a diagnostic roller to evaluate tire and wheel geometry, including radial runout. ProMatch™ helps technicians identify how the tire and wheel can be matched to reduce shape-related vibration, while ProBalance Technology® addresses static and couple unbalance. Together, these technologies help technicians diagnose difficult ride complaints, minimize rework, and help prevent customer comebacks.

Features and Benefits:

• ProMatch™ Diagnostics: Uses diagnostic measurements to help identify and correct tire and wheel geometry issues that can contribute to vibration even when conventional wheel balance is within specification.
• Diagnostic Roller: Measures radial runout and evaluates the tire and wheel assembly for ride-quality conditions that may not be corrected by wheel weights alone.
• ProBalance Technology®: Coats' advanced unbalance correction methodology is designed to minimize both static and couple unbalance for a more complete performance balance.
• Coats Direct Drive Technology: Integrates the motor and spindle into a single factory pre-balanced assembly for accurate, dependable wheel balancing without conventional belts and pulleys.
• 3D Automatic Data Entry: Automatically captures wheel distance, diameter, and width to reduce manual measurements, minimize technician input errors, and speed up wheel setup.
• Multi-Function Laser Module: Helps measure wheel dimensions, guides corrective weight placement, and assists technicians in identifying rim-related conditions.
• Sonar Width Measurement: Automatically measures wheel width as part of the 3D data-entry process.
• Laser Guided Weight Placement: Visually identifies corrective weight locations to help technicians accurately position weights with less trial and error.
• Stop, Lock & Index: Automatically rotates the wheel to the proper corrective weight position and locks the spindle in place for easier and more accurate weight application.
• Speed Thread: Allows the technician to quickly thread the hub nut using a pedal, reducing repetitive manual effort during wheel mounting and removal.
• Touchscreen Interface: Provides intuitive access to balancing and diagnostic functions while helping simplify technician training and everyday operation.
• LED Barrel Lighting: Illuminates the inside of the wheel to improve visibility during inspection and corrective weight placement.
• Behind-the-Spoke Mode: Allows adhesive corrective weights to be positioned behind wheel spokes for a cleaner finished appearance on alloy and custom wheels.
• 8 Balancing Modes: Provides the flexibility needed to service a wide variety of passenger car and light truck wheel configurations.
• 160 lb. Maximum Wheel Weight: Accommodates a broad range of passenger car, SUV, and light truck wheel and tire assemblies.

ProMatch™ Ride Diagnostics:

Not every vibration problem can be corrected by adding or repositioning wheel weights. A tire or wheel that is out of round can create a ride disturbance even after a conventional balancer indicates that the assembly is properly balanced. The E900's diagnostic roller evaluates tire and wheel geometry and measures radial runout to help technicians identify these conditions before the wheel is returned to the vehicle.

ProMatch™ uses this diagnostic information to help the technician determine how the tire and wheel can be matched to minimize shape-related vibration. This provides shops with an additional tool for diagnosing difficult ride complaints and can help reduce unnecessary rebalancing, rework, and customer comebacks.

ProBalance Technology®:

While ProMatch™ addresses tire and wheel geometry, ProBalance Technology® focuses on correcting weight imbalance. Coats' advanced unbalance correction methodology is designed to minimize both static and couple unbalance, helping technicians achieve a more complete performance balance.

By combining ProBalance Technology® with ProMatch™ diagnostics, the E900 addresses both major sides of ride-quality service: correcting weight imbalance and identifying tire or wheel conditions that corrective weights alone may not solve.

Coats Direct Drive Technology:

The E900 is built around Coats' proven Direct Drive platform. The motor and spindle are integrated into a single factory pre-balanced assembly rather than relying on a conventional belt-and-pulley drive system. This design is engineered to provide accurate, consistent balancing results with fewer drive components to wear over time and less need for frequent calibration.

3D Automatic Data Entry:

The E900 automatically captures the wheel's distance, diameter, and width using its advanced measurement systems, including sonar width measurement. Automating wheel measurements reduces manual setup, helps minimize technician input errors, and allows the balancing process to begin faster and more consistently.

Laser Guided Weight Placement:

The multi-function laser system assists with wheel measurement and visually identifies corrective weight locations. This helps technicians accurately position adhesive weights while reducing the trial and error associated with manually locating the proper placement point.

Stop, Lock & Index:

After determining where corrective weight should be applied, Stop, Lock & Index automatically rotates the wheel to the proper weight-placement position and locks the spindle in place. Combined with laser guidance and LED barrel lighting, the system helps make corrective weight placement fast, visible, and precise.

Speed Thread:

Speed Thread improves wheel mounting efficiency by allowing the technician to thread the hub nut using a pedal instead of repeatedly spinning it by hand. In high-volume tire service environments, eliminating this repetitive step can help reduce technician effort and improve overall service productivity.

Designed to Reduce Diagnostic Guesswork and Comebacks:

A conventional wheel balancer can accurately identify and correct weight imbalance, but weight imbalance is not the only potential cause of a vibration complaint. By adding radial runout measurement and tire/wheel geometry diagnostics to the balancing process, the E900 gives technicians additional information before returning the vehicle to the customer.

This makes the E900 especially valuable for shops servicing premium vehicles, performance tires, low-profile assemblies, larger wheels, and customers with difficult or recurring ride-quality complaints. Identifying a tire or wheel problem during the initial service can help reduce unnecessary rebalancing and improve first-time repair results.

Optional E900 PROKIT:

For shops looking to maximize productivity and wheel-mounting accuracy, the E900 is available with the optional PROKIT featuring the Coats 525 Auto-Down Wheel Lift and Adjustable Pin Plate Set. The wheel lift helps technicians position heavier wheel assemblies on the balancer while reducing lifting strain, and the adjustable pin plates provide an additional precision mounting solution for applicable wheel assemblies.

Why Choose the Coats ProBalance E900?

The Coats ProBalance E900 is designed for shops that want to go beyond conventional wheel balancing and diagnose the causes of difficult ride-quality complaints. It combines ProMatch™ diagnostics, ProBalance Technology®, a diagnostic roller, 3D automatic data entry, Direct Drive technology, laser-guided weight placement, Stop, Lock & Index, Speed Thread, and touchscreen operation in one advanced professional wheel service system.

Compared with the Coats 1600-3D, the E900 adds the diagnostic capability to evaluate radial runout and tire/wheel geometry rather than relying solely on corrective weight balancing. For high-volume shops, dealerships, tire stores, and service facilities that want to reduce diagnostic guesswork and wheel-balance comebacks, the Coats ProBalance E900 Diagnostic Wheel Balancer is the premium diagnostic solution in the Coats lineup.
