STATEMENTS OF CONFORMITY
105 INFORMATION
Incomplete vehicle weight and dimensional information
required for center of gravity calculations are available in
the Ford Source Book. See your local Ford Dealer and
refer to appropriate model year and specific vehicle for
required information.
Abbreviation definitions and a vehicle diagram to assist
with the equations for the Standard 105 segment are
shown on page 10.
105 The statements below are applicable to the Chassis
Cab:
This vehicle, when completed, will conform to Standard
105, Hydraulic and Electric Brake Systems, if:
• No alterations, modifications, or replacements are
made to the following:
– Service or parking brake system
– Antilock brake system
– Vacuum system
– Wheels and tires
– Brake system indicator lamp and wiring
– Brake system reservoir labeling
– Suspension ride height or spring rate
– Hydro-boost system
– Power steering pump and lines if used with
Hydro-boost
– Engine belt drive system
• No additional sound deadener or rust proofing material,
that may be applied to the vehicle, can interfere with
proper parking brake cable function.
• No part of add on equipment, i.e. toolboxes, flat
bed attaching brackets, etc., can interfere with the
movement of parking brake cables or air flow to rear
brake assembly.
• Any removal of a Ford body or chassis component is
accompanied by the addition of equal weight.
• Chassis Cab vehicles with a GVWR of 4536 kg [10,000
lb] or less do not exceed the Maximum Unloaded
Vehicle Weight value in Table F, page 11.
• The applicable GAWRs and GVWR weights are not
exceeded.
• The completed vehicle must have a vertical center
of gravity (Equation A) of 48.00 inches or less when
measured from the ground.
• The front axle curb weight of the completed vehicle
(incomplete vehicle weight + min SUB weight, Table
G, page 12) may be reduced by no more than 10%
for SRW or 25% for DRW vehicles, using the front
axle ground reaction as manufactured by Ford Motor
Company.
• The rear axle curb weight of the completed vehicle
(incomplete vehicle weight + min SUB weight, Table
G, page 12) must be the same or greater than the rear
axle ground reaction as manufactured by Ford Motor
Company.
REFERENCE: Equation B can be used to determine the
completed vehicle’s horizontal center of gravity (CGh).
Abbreviation definitions and a vehicle diagram are
provided to assist with the equation on page 10.
