Alternatively, the self-supporting body structure • Holes should be in groups of two (2), either can also be designed as shown in figure shown. vertically spaced at 30 to 35mm from chassis frame top and/or bottom surface, or • This concept is based on a self-supporting structure where the floor is mounted directly onto the top surface of the chassis frame. • See figure shown for a generic vehicle cross section where the cross members and opposing out riggers are flush with the surface of the chassis frame side members. • It is important to the overall function of the vehicle structure that the out riggers are each connected to a continuous longitudinal floor side frame or a structural body side structure assembly. Low floor-re-work for guidance only: • Engineer unique cross members and out-riggers spaced at approximately 600mm maximum pitch. Out-rigger moment to be re-acted with • cross-member between chassis frame with common through bolts where possible. • Drill frame and add spacer tubes. Refer to: 5.5 Frame and Body Mounting (page 50). • Out-rigger outboard ends should be attached to load bearing body side / floor edge frame or body side structure (including over wheel support). • Structural wheel box should maintain longitudinal continuity with a rigid attachment to the floor edge frame or to the body side structure. • Floor boards should be substantially attached to cross members and outriggers, but not to the chassis frame top surface. • Low floor exhaust heat shields. 5.5.3 Frame Drilling and Tube Reinforcing The chassis frame may be drilled and reinforcing spacer tubes may be welded in place, providing the following is applied: • Adhere to all details shown in figure. • Drill and weld only side walls of the chassis frame. • Locate and drill holes accurately, using a drill guide to ensure holes are square to frame vertical center line (note: allow for side member draft angle). Drill undersize and ream out to size. • • Endeavor to remove all swarf from inside side member, and treat to prevent corrosion. • Fully weld each end of the tube and grind flat and square, in groups if applicable. Be aware of side member draft angle. • Apply corrosion protection inside and outside of the chassis frame. Refer to: 5.4 Corrosion Prevention (page 49). FordRanger 2011.5 horizontally at 50mm minimum pitch, 30 to 35mm from top and/or bottom chassis frame surface. • Always use M10 bolts with grade 8.8 minimum. • Do not position tubes at the medium chassis frame height, this may create “oil canning” of the deep section side walls. • Where possible, the outrigger moments should be resolved by matching inner cross members between the chassis side members inline with the outriggers. • A diameter of 16.5mm is the maximum allowable hole size in the chassis frame side wall, irrespective of the usage. Avoid drilling into closed frame body members to avoid the risk of corrosion from swarf. Refer to: 5.4 Corrosion Prevention (page 49). Drilling and welding of frames and body structure have to be conducted following the program guidelines. Please consult the Ford dealer for details. 5.5.4 Ancillary Equipment - Sub Frame Mounting Typical sub-frames and longitudinal members for flatbed and low or drop-side bodies or equipment exceeding the standard or Regular Production Order frame length should adhere to the following guidelines: Flat-beds and low bodies mounted on integral • longitudinal members (channel or box section metal – not wood) must use both sides of all frame mounting brackets. • Longitudinal members must be relieved at the front end if they are to contact the chassis frame top surface, to minimize stress concentrations. It is preferable however, to mount the longitudinal onto the mounting brackets, with a clearance to the chassis frame top surface. • Each set of brackets must use two (2) x M10 bolts grade 8.8 minimum. • Minimum floor heights will require wheel arch boxes to clear the rear tires, see Vehicle Data sheets for relevant tire jounce. 5.5.5 Area for Fitting Additional Body Attachments to the Rear of the Bumper. NOTE: With the vehicle on level ground and with all measurements taken rear ward of the bumper bar edge: The area designated for the fitting of attachment is defined as 220mm horizontally by 95mm vertical downward to the road surface, with a max width of 1390mm about vehicle center line.
