12/09Section 7Frame Modifications7-3FIGURE 7-2. Frame InsertWhere possible, use existing bolt holes to attach the insert to the frame. Bolt holes must not be located closer to the framefl anges than the present bolt pattern.If the insert is placed in a section of the main frame where few bolts are located, additional bolts are required. Use the fol-lowing guideline for locating additional bolt holes.CHANGING WHEELBASEWe do not recommend modifying the wheelbase. Occasionally, however, a chassis wheelbase will need to be reduced orlengthened. When this needs to be done there are a few guidelines that should to be considered.When changing the wheelbase, be sure to follow the driveline manufacturer’s recommen-dations for driveline length or angle changes. Incorrectly modified drivelines may fail pre-maturely due to excessive vibration. Failure to comply may result in personal injury, death,equipment or property damage.When changing the wheelbase, a continuous blank frame insert/outsert must be added inthe area of the new rear suspension mounting bolts. All new mounting holes must passthrough the original rail and the insert/outsert. Failure to do so may cause excessivestress in the original rail due to additional holes. Failure to comply may result in personalinjury, death, equipment or property damage.When relocating a suspension bracket, do not mount it on the extended (added) sectionof a frame rail. The suspension loading may result in premature failure of the added sec-tion splice. Use care when planning the wheelbase so that the rear suspension bracket isalways mounted on the original rail section. See Figure 7–3. Failure to comply may resultin personal injury, death, equipment or property damage.24 InchMinimum(610 mm)WARNING!WARNING!WARNING!WELDEDJOINTBefore changing the wheelbase the driveline angles of the proposed wheelbase need to be examined to ensure that noharmful vibrations are created. Consult the driveline manufacturer for appropriate recommendations.Before the rear suspension is relocated, check the new location of the spring hanger brackets. The new holes for thespring hanger brackets must not overlap existing holes and should not come any closer than 2 inches (50 mm) to existingholes in the frame. |
