Page 4: How It Works
HOW IT WORKS The TL-12 wheel alignment system measures Caster, Camber, SAI, and Toe. Two-wheel, thrust angle, and four-wheel can be done easily, with speed and accuracy. These alignments can also be referenced to the mechanical centerline of the vehicle. Depending on the type of vehicle being aligned, the technician chooses which alignment to do. -
Page 5: General Alignment Procedure
GENERAL ALIGNMENT PROCEDURE The following section is an overall guide for performing an alignment with the TL-12. The steps listed below are meant to give a basic understanding of what procedures are used, and how they are performed, to accomplish wheel alignment. The steps given should generally be followed in the same order as they have been placed. - Page 6 5) Lower the car and jounce the car to settle the suspension. Be sure that the front turning plates and rear slip plates are released and move freely. 6) Hang the TL-30 on the left front wheel clamp to measure camber, caster and SAI a) For camber readings: with the tire in a straight-ahead position, note the reading of the camber bubble on the TL-30.

Page 8: Calibration Procedures
CALIBRATION PROCEDURES Using the TL-40 Calibration Bar, you are able to calibrate the TL-12 wheel alignment system, which consist of the TL-30 EZ Check Gauge, TL-36 right Laser Gun, TL-37 left Laser Gun, TL- 38 right Combi, and TL-39 left Combi. For maximum accuracy, it is important to check and, if... - Page 9 First: Calibrating the camber of the TL-30, TL-38, and TL-39. Note: There is a pivot plate at the end of the TL-40, which has a mounting disc attached to the end, a master bubble vial affixed to the plate, and an adjustment knob. The pivot plate is designed to eliminate any pitch in the bar or non-level surface.

Place the Laser Guns on the disks at the slot location located on the bottom of the Laser Guns, push down until you here a click.

Note: Be sure that the camber has already been calibrated on each Combi gauge and the Laser Guns have been calibrated with the Fixed Return Mirrors. 1) If the Combi Gauges are not already on the disks closest to the Fixed Return Mirror (with the mirrors facing the Laser Guns), place them there.

Page 14: Mounting Tl-28 Wheel Clamps
MOUNTING TL-28 WHEEL CLAMPS The wheel clamps can be attached to either the inside or the outside of the rim (whichever is easiest). They can be mounted on a wheel rim 10 inches to 19 inches in diameter, and the aluminum feet are less likely to damage polished aluminum rims. -
Page 15: Run Out Procedure
RUN OUT PROCEDURE Once the wheel clamps have been mounted, run out should either be performed on the two front wheels or all four, depending what type alignment is preferred. For a Two-wheel Centerline alignment, adjust run out on both front wheels. For a Thrust Angle alignment, or Four-wheel total alignment, adjust run out on all four wheels. - Page 16 Caster Zero Adjustment Caster Zero Adjustment Red Adjustment Knob Recommended Runout Procedure...

Page 17: Accomidating Oversized Truck Tires
ACCOMIDATING OVERSIZED TRUCK TIRES Although the Tru-Line TL series alignment system is designed to align vehicles with rim diameters up to 19”, alignment of vehicles with larger rim and tire diameters is possible. By offsetting the center assembly of the TL-28 Wheel Clamp is to accommodate the laser to reach around the oversize tire as seen in the diagram below. -
Page 18: Measuring Camber
MEASURING CAMBER, CASTER, AND SAI Measuring Caster, Camber or SAI is very simple and fast. Before performing these measurements: • The equipment must be calibrated. • The wheel clamps must be mounted and adjusted for run out. • The full weight of the vehicle must be on its wheels •... -
Page 19: Measuring Sai
Measuring SAI: When measuring SAI, the Brake Pedal Depressor (TL-31) must be installed, so the wheel does not rotate. 1) Hang the TL-30 to the left front wheel clamp to measure camber, caster and SAI. 2) Install brake pedal depressor and lock the brakes so they do not rotate. With power brakes start the engine to install brake pedal depressor. -
Page 20: Live Caster Adjustment
LIVE CASTER ADJUSTMENT This scale allows you to monitor caster adjustments while making the changes the vehicle. The following caster adjustment procedure measure caster. 1) Hang the TL-30 on the left front wheel clamp. 2) Install brake pedal depressor and lock brakes so they do not rotate. With power brakes start the engine to install brake pedal depressor. -
Page 21: Two-Wheel Centerline Alignment
TWO-WHEEL CENTERLINE ALIGNMENT The purpose of a Two-wheel Centerline alignment is to align the front wheels to the theoretical centerline of the vehicle. This is accomplished by adjusting the front wheels to match up with the centerline of the vehicle. Note: the Two-wheel Centerline procedure is the first step of the Thrust Angle and Four-wheel alignments. - Page 22 Two-wheel centerline alignment procedure: 1) Lock steering wheel in the center position 2) Hang TL-38 and TL-39 Combi gauges on the rear wheels, with the Centering scale facing towards the front of the vehicle. Set the toe dials to zero. 3) Hang the TL-36 and TL-37 Laser Guns on the front of the vehicle;...

Page 24: Thrust Angle Alignment
THRUST ANGLE ALIGNMENT The purpose of a Thrust Angle alignment is to adjust the front wheels until they are aligned with the rear axle. This alignment is typically done to vehicles that have no rear wheel adjustment available. This type of alignment gives the customer a straight steering wheel and minimizes tire wear on the front only, and allows you to measure which direction the rear of the vehicle is inclined to travel, or the thrust angle of the vehicle. - Page 25 TL-37 TL-36 TL-39 TL-38 Thrust Angle Alignment...

Page 26: Four-Wheel Alignment
FOUR-WHEEL ALIGNMENT The objective in a Four-wheel alignment is to adjust all four wheels until they are aligned to the factory specification. This alignment is typically done to vehicles that have rear wheel adjustment available. The following should be completed before making any measurements or adjustments: 1) Equipment should be checked for calibration. -
Page 27: Four-Wheel Alignment
Four-Wheel Alignment: 1) Lock steering wheel in the center position, or until the front wheels are in the straight- ahead position. 2) Hang TL-38 and TL-39 Combi gauges on the rear wheels with the Centering scale facing toward the front of the vehicle. Set toe dials to factory toe specification. 3) Hang the TL-36 and TL-37 Laser Guns on the front of the vehicle;... - Page 28 Front of Car TL-37 TL-36 Thrust Angle Laser Gun Laser Gun Scale 9 8 7 6 5 4 3 2 1 1 2 3 4 5 6 7 8 9 Steering Wheel Locked Straight Ahead.
