CRITICAL CLEARANCES
Rear Wheels and Cab
CAUTION:
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 5-2.)
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 5-2.
Figure 5-2. Minimum Clearance Between Top Of Rear Tires And Body Structure Overhang.
CAUTION:
Maintain adequate clearance between back of cab and the front (leading edge) of mounted
body. See Figure 5-2.
Note:
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 13.3 inches (337.8mm) for K270 and 11
inches for K370 (279.4 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 17.3
for K270 and 15 inches for K370 (381
mm) from the front axle to the leading edge of the body (A).
See SECTION 3 “DIMENSIONS” for further details on dimensions and clearances.
Also, see APPENDIX B “WEIGHT DISTRIBUTION” for explanation of back–of–cab (BOC)/CA calculations.
