Body tie-down holes should only be drilled in top flange no larger than 0.76 in diameter;
centerline of holes should be 1.0 to 1.12 in. from the web side of the frame rail. Minimum
distance between edges of the holes should be approximately 2.0 in.
Trailer Towing
The Incomplete Vehicle Document also specifies that the CG location be within certain
limits for proper brake balance, and may be more restrictive than the data mentioned
above. The Body Builder must use all appropriate data.
NOTE:
Failure to keep body and payload CG at least 26” forward of centerline of rear
axle will result in degradation of trailer towing capacity. Consult with your Body
Builder/Final Stage Manufacturer to determine maximum tongue load for your
vehicle.
Section 3 – Front Suspension
See chassis data information for clearances and assistance in calculating trim heights.
Clearance should be provided for the tire used while in full jounce (upward travel) against
metal stops and at full left-hand and right-hand turn. The envelopes will be provided
upon request. See
Section 5 - Brakes.
Allowance for the tire chain clearance shown on a maximum grown tire must allow for
(1.66 in.) clearance to the sides of the tire and (2.5 in.) to the top of the tire. Be sure suffi-
cient clearance is provided for suspension, axle and tire and wheel in full vertical travel
(up and down).
NOTE:
Notification to the consumer may be required in certain states if tire chains
cannot be used.
Vehicles equipped with 3650 lbs. low height independent front suspension (IFS). The
urethane air cylinders must be maintained at 70 psi. If the vehicle is also equipped with
option 9Q6, right side air cylinder should be set at 50 psi instead of 70 psi. Vehicles
equipped with 4500 and 5000 lbs. independent front suspension (IFS) urethane air cylin-
ders must be maintained at 50 PSI; with 5500 lbs. independent front suspension, air cyl-
inders must be maintained at 90 psi. Air cylinders when provided must be shielded dur-
ing welding operations.
Since there is a large variation in completed vehicle front weight due to differences in
body weight and equipment, the front suspension alignment (caster, camber and toe)
must be checked and reset if necessary after the vehicle is completed. The suspension
must be reset by the Body Builder if it is found that the setting’s do not conform to the
specifications as outlined in the “P” Chassis Service Manual. On P 30042 trucks with
I-beams, camber and caster is designed into the axle/suspension and cannot be ad-
justed.
See Truck Service Manual for complete alignment procedure, specifications under
“Diagnosis and Front Alignment” section.
The following statement applies to P 30042 models with I-beam front axle.
The front crossmember steering gear attachment is a weldment. Under no conditions
may the flanges be cut or notched out in any manner. Any alteration would severely af-
fect steering attachment capabilities.
Section 4 – Rear Suspension
Clearance to body should be provided for the suspension, axle, driveshaft and tires un-
der the following conditions: (1) Axle in full jounce against the metal-to-metal stop, (2)
Axle at 4.5
_
roll with one side of axle in full jounce at the metal to metal stop and (3) Axle
at design position. Allowance for the tire chain clearance shown on a maximum grown
tire must allow for (1.66 in.) clearance to the sides of the tire and (2.5 in.) to the top of
the tire. Be sure sufficient clearance is provided for suspension, axle and tire and wheel
in full vertical travel (up and down).
NOTE:
Notification to the consumer may be required in certain states if tire chains
cannot be used.
Pipes, wiring, conduits and any other related components must not be placed where they
cross the path of motion of the rear axle, driveshaft, axle brake pipes, hoses, spring or
tires. Such crossing could result in rupture, wear-through, or separation due to normal
axle motion.
See chassis data information for additional clearances and for assistance in calculating
trim heights.
Section 5 – Brakes
See Truck Service Manual for brake specifications.
Due to the critical nature of brake systems, anyone making modifications or alterations
must assume complete responsibility for system reliability, performance and certification
to FMVSS 105 or FMVSS 121.
