Hunter Alignment Machine Essentials

When considering a wheel alignment for your vehicle, the name Hunter often comes to the forefront. Hunter Engineering is a leading manufacturer of automotive service equipment, and their alignment systems are renowned for their accuracy and advanced technology. But what exactly is included in a Hunter alignment machine, and what makes it a preferred choice for many garages and dealerships? This article delves into the core components and features that define a Hunter alignment system, helping you understand the investment and the benefits it brings to your vehicle's maintenance.

Understanding Wheel Alignment

Before we explore the specifics of Hunter machines, it's crucial to understand the purpose of wheel alignment. Wheel alignment refers to the adjustments made to your vehicle's suspension and steering components to bring the wheels into the manufacturer's specified angles. Proper alignment is vital for several reasons:

• Tyre Wear: Misaligned wheels can cause uneven and premature tyre wear, leading to costly replacements.
• Fuel Efficiency: When wheels are not aligned correctly, they create more rolling resistance, forcing your engine to work harder and consume more fuel.
• Handling and Stability: Proper alignment ensures your vehicle steers straight, maintains stability during driving, and responds predictably to steering inputs.
• Driving Comfort: A misaligned vehicle can pull to one side, causing you to constantly correct the steering, which is both tiring and unsafe.

The Hunter Alignment System: Core Components

A modern Hunter alignment machine is a sophisticated piece of equipment that combines hardware and software to provide precise measurements and adjustments. While specific configurations can vary depending on the model, the fundamental components typically include:

1. Measuring Heads (Sensors/Cameras)

This is arguably the most critical part of the alignment system. Hunter's advanced systems utilise sophisticated optical technology, often employing high-definition cameras and sophisticated imaging sensors. These measuring heads are mounted on each wheel and capture precise data about the wheel's position and angle relative to the vehicle and the ground.

Key features often found in Hunter measuring heads:

• 3D Imaging: Utilising multiple cameras to create a 3D model of the vehicle's wheel and suspension geometry.
• Target Plates: Special reflective or active (powered) target plates are mounted on the wheels. These targets are precisely designed to be read by the cameras, providing highly accurate positional data.
• No Electronic Components on Wheels: A significant advantage of many Hunter systems is that the measuring heads themselves are passive, meaning they don't have batteries or electronic components that can fail on the wheel. All the "brains" are in the main console.
• Automatic Leveling: Some advanced systems feature automatic leveling of the measuring heads to compensate for minor variations in the lift or pit.

2. Wheel Clamps (Adaptors)

Securely attaching the measuring heads to the wheels is paramount. Hunter offers a range of robust and user-friendly wheel clamps designed to fit various wheel sizes and types, including alloy, steel, and even exotic materials. These clamps are designed to grip the wheel securely without damaging the rim.

Considerations for wheel clamps:

• Versatility: The ability to accommodate a wide range of wheel diameters and widths.
• Secure Fit: Ensuring the clamp does not slip during the measurement process.
• Rim Protection: Padding or design features to prevent scratches or dents on the wheels.
• Fast Mounting: Ease and speed of installation and removal for efficient workflow.

3. Vehicle Lift or Alignment Rack

To perform an alignment, the vehicle needs to be raised to a height that allows technicians access to the suspension components. Hunter alignment systems are often integrated with or designed to work seamlessly with specific types of lifts, such as:

• Four-Post Lifts: These are common in many workshops and provide a stable platform.
• Scissor Lifts: Often used for pit-style alignments or where space is limited.
• In-Ground Lifts: These are integrated into the workshop floor, offering a clean aesthetic and excellent access.

The lift must be level and stable, as any tilt can introduce errors into the alignment measurements. Hunter often provides specialised "slip plates" or "slip pads" that are integrated into the lift platforms. These allow the wheels to move freely in the direction of adjustment without binding, which is crucial for accurate caster and camber adjustments.

4. Computer Console and Software

The "brain" of the Hunter alignment system is its powerful computer console and proprietary software. This is where all the data from the measuring heads is processed, analysed, and presented to the technician.

Key features of the software and console:

• Extensive Vehicle Database: Hunter systems contain a vast database of vehicle specifications, including camber, caster, toe, and thrust angles for thousands of makes and models. This allows for quick selection of the correct alignment parameters.
• Real-Time Measurements: The software displays live readings as adjustments are made, allowing technicians to see the effects of their work instantly.
• Graphical Displays: Sophisticated visualisations help technicians understand the alignment readings and identify any deviations from the manufacturer's specifications.
• Printouts: Before and after alignment printouts provide a clear record of the work performed and demonstrate the improvement in alignment angles to the customer.
• Advanced Measurement Features: Depending on the model, Hunter systems can measure various advanced alignment parameters, such as KPI (Kingpin Inclination), Included Angle, SAI (Steering Axis Inclination), and Setback.
• "Power-In" Turnplates: For front-wheel-drive vehicles, specific procedures require the front wheels to be steered. Hunter systems often include "power-in" turnplates that assist in achieving the correct steering angles for accurate caster measurements.

5. Accessories and Calibration Tools

To ensure the ongoing accuracy of the system, calibration is essential. Hunter systems typically come with specific calibration tools and procedures. Regular calibration ensures that the measuring heads and software remain in sync and provide reliable data.

Other accessories might include:

• Brake Pedal Depressors: To hold the brake pedal down during the alignment process.
• Steering Wheel Alignment Cords/Holders: To ensure the steering wheel is centred correctly.
• Locking Collars: To hold suspension components in place while adjustments are being made.

Hunter's Advanced Technologies (e.g., HawkEye®)

Hunter is known for its continuous innovation. One of their flagship technologies is the HawkEye® alignment system. HawkEye® utilises multiple high-definition cameras to provide a comprehensive view of the vehicle's wheel and suspension geometry. This advanced imaging technology allows for:

• Faster Readings: Quick and efficient measurement of alignment angles.
• Increased Accuracy: Minimising potential errors associated with traditional methods.
• Identification of Damage: The system can sometimes detect subtle damage to suspension components or wheels that might not be immediately obvious.
• "No-Touch" Capabilities: In some configurations, the system can perform measurements without physically touching the wheel targets, relying purely on optical data.

What to Expect During a Hunter Alignment

When you take your vehicle to a workshop equipped with a Hunter alignment machine, you can expect a thorough and precise procedure. The technician will typically:

1. Secure the vehicle onto the lift using appropriate wheel clamps.
2. Mount the measuring heads onto each wheel.
3. Select your vehicle's make, model, and year from the Hunter software database.
4. Perform initial measurements to determine any deviations from the factory specifications.
5. Make the necessary adjustments to the suspension components (e.g., tie rods, control arms).
6. Re-measure after adjustments to confirm that all angles are within tolerance.
7. Provide you with a printout detailing the "before" and "after" alignment readings.
