Machine Preparation:
NOTE: Alignments should be performed on a level surface. Height of tire patches should be
within 1/8” of each other.
•For field alignment configure the machine in the most common roading condition
and inflate all tires to 130 psi.
•Drive vehicle straight into inspection site, at least 3 full tire rotations to ensure
it’s straight into site. Driving into and backing out of the work area several times
will ensure the vehicle’s suspension components remain relaxed to achieve
proper measurements.
•For final positioning, shift transmission to neutral and allow vehicle to roll
forward to a stop without using the brakes.
•Engage parking brake.(Note: Outriggers do not function unless park brake is engaged.)

Machine Preparation continued:
•Adjust ride height - front and rear.
Note: When setting ride height and measuring alignment settings be certain that the air
system is at full system pressure; re-charge frequently.
•Place wheel chocks on drive axles and release the park brake.
•Place a calibrated digital angle gauge on the flat surface of the trailing arm
and adjust the ride height valve to achieve a 1.8°+/-0.5°angle, open to the
rear. Repeat the process on all four tandems and maintain a 0.5°tolerance
between left and right on the same tandem.
Note: Calibrate/zero digital angle gauges to the bottom frame rail, positioned in the same
orientation that each is being applied on the suspension.
•Prepare for toe adjustment if it is required:
•Raise the machine on outriggers until the tires are just off the ground.
•Prepare the steer tires for toe measurement by highlighting (white spray
paint) a section/row of tread around each tire and scribing a line into the
highlight around the tires as they are rotated.
•Lower the machine to the ground. Back out and drive straight into the work
area several times to ensure the vehicle’s suspension components remain
relaxed and achieve proper measurements. Place wheel chocks on the drive
axles.

Adjust axle offset.
•Measure the distance between the frame side plate to the edge of the tire tread
centered over the axle, left and right; these measurements should be within
3/16 in. (4.8 mm).
Note: steering axle and drive axle measurements will be different; axle lengths and frame
widths are different.
Measure to edge of tread
•Adjust side to side using lateral torque rods. Re-torque bolts 2 to 3 turns into the
locking feature of the nut.
Note: Machine should be on outriggers to perform this adjustment.
Adjust each axle using the lateral torque rod.
•Lower the machine to the ground. Back out and drive straight into the work
area several times to ensure the vehicle’s suspension components remain
relaxed and achieve proper measurements. Place wheel chocks on the drive
axles.

Adjust steer axle skew.
•Raise the machine on outriggers and place an alignment turntable under each of
the steer tires. Lower the machine making certain not to bottom-out the
turntables or put them in a bind.
•Measure the distance between the “center hook” on the frame to the corner of the
front steer axle mount, left and right; each axle’s left and right measurements
should be within 3/16 in. (4.8 mm) of the other.
#1 axle Center hook location
•Adjust axle mounting shims to achieve squareness. Reposition the shim/s to the
front of the bar pin to move the axle forward, or to the back of the bar pin to move
the axle toward the rear. Slight adjustments might be achieved by adjusting
shims on one side of the axle. Larger adjustments will be achieved by adjusting
both sides in opposite directions. Re-torque hardware to 450-600 lbf*lb. (610-
813 N*m).
Note: Raise the machine on outriggers to take weight off the suspension in order to reposition
the mounting shims. A Porta Power can be used to support the suspension. Be sure to lift the
outriggers and put full weight on the suspension prior to taking subsequent measurements.

Adjust steer axle parallelism.
•Distance between the steer axle hub centers on the left and right side of the
machine should be within 1/8 in. (3.2 mm).This can be measured, or the
process can be simplified by use of a Trammel bar if available.
•Adjust rear steer axle mounting shims to achieve parallelism. Reposition the
shim/s to the front of the bar pin to move the axle forward, or to the back of the
bar pin to move the axle toward the rear. Slight adjustments might be achieved
by adjusting shims on one side of the axle. Larger adjustments will be achieved
by adjusting both sides in opposite directions. Re-torque hardware to 450-600
lbf*ft. (610-813 N*m).
Note: Raise the machine on outriggers to take weight off the suspension in order to reposition
the mounting shims. A Porta Power can be used to support the suspension. Be sure to lift the

Adjust steer wheel-end toe.
•Toe should be +1/32 in. (0.8 mm) +/-1/32 in. (0.8 mm).
Note: Steer tires should be on alignment turntables for this step.
•On the front steer axle measure the distance between the scribed lines (see
“machine preparation for toe adjustment”) at hub height on the rear of the tires
and then on the front of the tires. Subtract the front value from the rear.
Positive result is “toe in” and negative is “toe out.” The use of a “toe bar”
provides greater accuracy.
Adjust the front steer axle tie rod to achieve this. Apply Loctite 243 to clamp bolts
and re-torque to 115-125 lbf*ft. (156-169 N*m).
•Repeat this process for the rear steer axle.
