CRITICAL CLEARANCES
Rear Wheels and Cab
Insufficient clearance between rear tires and body structure could cause damage to the
body during suspension movement. Allow at least 8 inches clearance (See Figure 6–1.)
Normal suspension movement could cause contact between the tires and the body. To prevent this, mount the body so
that the minimum clearance between the top of the tire and the bottom of the body is 8 inches (203 mm) . This should be
measured with the body empty . See Figure 6–1 .
FIGURE 6-1. Minimum Clearance Between Top of Rear Tires and Body Structure Overhang
Maintain adequate clearance between back of cab and the front (leading edge) of
mounted body. Failure to do so could cause damage to the cab, body or both during cab
& body movement. See Figure 6–2.
Be sure to provide maintenance access to battery box and fuel tank fill neck.
The true distance from the centerline of the front axle to the back of the cab is 68 inches (1727 mm) . It is recommended
that the leading edge of the body be mounted a minimum of 4 inches (102 mm) behind the cab . The result is a minimum
back–of–cab clearance of 72 inches (1829 mm) from the front axle to the leading edge of the body .
See SECTION 3 “DIMENSIONS” for further details on dimensions and clearances . Also, see APPENDIx B “WEIGHT DIS-
TRIBUTION” for explanation of back–of–cab (BOC) / CA calculations .

If the frame rail flanges are modified or damaged, the rail may fail prematurely and cause
an accident. When mounting a body to the chassis, DO NOT drill holes in the upper or
lower flange of the frame rail. Mount the body using body mounting brackets or U-bolts.
Failure to comply may result in personal injury, death, equipment or property damage.
