Step-by-Step Aligner Pre-Install Checklist

Hi everyone! I’m Kyle from COATS, and today I’m going to walk you through your COATS 3D Aligner pre-installation checklist. If you’re preparing your shop for a new CWA 6500 3D Wheel Aligner, this guide will help you avoid common setup mistakes and ensure your alignment equipment is installed and functioning correctly.

Let’s dive into each step, starting with the alignment lift.

Choosing the Right Alignment Lift

One of the first things to decide is the type of alignment lift you’ll be using. We recommend either a 4-post or a scissor alignment lift for performing light-duty alignments.

Among these, the scissor lift is often preferred. Why? Because it gives the COATS 3D Aligner cameras a clearer line of sight to the targets—especially important for wider vehicles.

If you don’t already have a suitable lift, visit Coats Company and use our lift comparison tool to choose one that fits your needs.

Inspecting Rolling Bridge Jacks

Next, check if your lift has rolling bridge jacks—these are essential. Whether hydraulic or air-operated, they roll between the lift runways and let technicians raise the vehicle for adjustments and repairs related to alignment.

Without these, achieving a true raised adjust mode isn’t possible, so they’re a key component of your setup.

Planning for Long Vehicles and Wheelbase Fit

Are you aligning long vehicles like crew cab trucks? Make sure your alignment lift can handle their full wheelbase, plus leave enough room for rolling compensation—that’s when the vehicle rolls forward and backward during the alignment process.

Also, consider the weight capacity of your lift. It must safely support the heaviest vehicles you plan to service.

Measure from the front to the back of the runway, excluding approach ramps, and double-check if your alignment lift runways are long enough for the job.

Ensuring the Lift is Level and Straight

Leveling is crucial! A twisted or uneven lift can result in incorrect alignment readings.

Use a 4T bubble level or a laser level to check the lift is level from side to side and front to back. Between the turn plates, no more than 1/32 of an inch (or 3 mm) variance is allowed for accurate alignment.

Power Requirements and Camera Positioning

Make sure a 115V outlet is nearby your alignment machine.

Proper camera-to-turn plate distance is also critical. Measure from the cameras to the front edge of the lift, and then from the turn plate center to the lift edge. These two measurements help ensure that the 3D aligner’s cameras are properly positioned.

Avoiding Environmental Obstructions

Where you install your aligner matters just as much as how you install it. Avoid placing your equipment in bays that face direct sunlight, as bright light can interfere with camera readings.

Also, steer clear of areas with floor drains or steep slopes. Irregular flooring can throw off your readings.

Be mindful of anything that might block the alignment beam—toolboxes, trash cans, fans, or shelving. Large fans or heaters near the camera may cause sensor interference or heat distortion.

Preparing Turn Plates and Slip Plates

Your turn plates and slip plates must be level with the runway. Use a bubble level to check for a variance no greater than 1/8 of an inch.

Ensure turn plate bridges are in place. These help with rolling compensation, a must for any 3D aligner.

Check that all locking pins are present and tight. With the pins removed, the turn plates should move freely without any binding or obstructions.

Final Survey Submission

Once you’ve checked everything—lift, alignment area, power, floor conditions, and equipment—attach any photos or notes to your install survey.
