5.2.4 AXLE ALIGNMENT (cont'd)
6. Attach an S hook to a steel tape and measure
the distance between the kingpin and the end
of each axle. Dimensions A and B should be
equal within ± 1/8 inch (0.125 in) (3.1 mm).
7. Adjust the suspension mounting system as
required to set dimension A and B within 1/8
inch (0.125 in) (3.1 mm). Refer to suspension
system instruction brochure for detailed
adjustment procedure.
8. Use a trammel bar to measure the road and
curbside dimensions between the first and
second axles. Dimensions C and D should be
within 1/16 inch (0.0625 in) (1.6 mm).
IMPORTANT
It may be necessary to build a large
trammel bar to measure and clear the
discharge gates.
9. Set the suspension system as required to set this
dimension to its recommended tolerance.
10. Repeat measuring and adjustment procedure on
the third axle if so equipped.
11. Tighten all fasteners to their specified torque. Do
not allow any suspension system or running gear
fasteners to loosen.
IMPORTANT
Always use a torque wrench when
tightening fasteners. The correct
torque on a fastener provides the
proper clamping force on the adjacent
components and they will perform as
expected.
12. The front axle must be aligned to the kingpin with
second and third axles adjusted to the front axle.
13. Always check axle alignment after repairing the
suspension system.
