Page 4: How It Works
How it Works The TLT-12 wheel alignment system measures Caster, Camber, SAI/KPI, Toe, Tracking/Tandem, and Offset. These alignments can reference the mechanical or actual centerline of the vehicle. Two-wheel centerline, tracking, and four-wheel total alignments can be made. Depending on the model of vehicle being aligned, the technician chooses which type of alignment to do. -
Page 5: Unpacking And Assembling The System
Unpacking and Assembling the System The system is shipped for the most part complete and ready to use. However, you will need to assemble a couple of items in order to use the system to its fullest capability. 1. To assemble the TLT-41 Calibration Bar (Fig. 1). Locate the bar which looks like a black bar with three disks on one end. - Page 6 3. Next you will find a pair of targets. These targets mount either on the King Pin Target kit, (Fig. 3) or the Wheel Chock Target Stands (Fig. 4). The targets have plastic thumbscrews for easy mounting and dismounting. Please note that when assembling these Targets, they must be mounted exactly mirror image from each other in order to obtain the highest accuracy.

Page 15: Mounting The Tlt-28 Wheel Clamps
Mounting the TLT–28 Wheel Clamps The wheel clamps, (Fig 12) can be attached to either the inside or the outside of the rim (whichever is easiest). They can be mounted on a wheel rim 17 inches to 25 inches in diameter, and the aluminum feet are less likely to damage polished aluminum rims. -
Page 16: Run-Out Procedure
Run-Out Procedure Once the wheel clamps have been mounted, a simple run-out procedure should be performed. The following should be completed before run out adjustments are made: • Front wheel clamps must be installed • The vehicle must be raised, so the wheels can rotate freely. Run Out Procedure: 1) Place the TLT-30 on the disk extending from the wheel clamp. - Page 17 Caster Zero Adjustment Figure 14 5) Level the TLT-30 and read the number on the caster scale. 6) Adjust the bubble to the point halfway between zero and the current reading using the RED knob on the TLT-28. (When making this adjustment, it is important not to move the bubble with the caster adjustment knob.) 7) Rotate the wheel ¼...
