  • Page 67: Frame Modifications

    Frame Modifications frame modificationS introduction Kenworth offers customer specified wheelbases. So, in most cases frame modifications to produce a certain wheelbase should not be necessary However, some installations may require slight modifications, while other installations will require extensive modifications. Sometimes an existing dealer stock chassis may need to have the wheelbase changed to better fit a customer’s applica- tion.

    Section 5 Frame Modifications modifying frame length The frame cutoff after the rear axle can be shortened to match a particular body length Using a torch is acceptable; however, heat from a torch will affect the material characteristics of the frame rail The affected material will normally be confined to within 1 to 2 inches (25 to 50 mm) of the flame cut and may not adversely affect the strength of the chassis or body installation The frame cutoff can be lengthened by adding frame extenders...

  • Page 70: Figure 5-3. Comparison Of Original, Shortened, And Extended Wheelbases

    Section 5 Frame Modifications when reducing the wheelbase, we recommend that the suspension be moved forward and relocated on the original rail The rail behind the suspension can then be cut to achieve the desired frame cutoff See Figure 5–3 Warning! Do not drill new holes any closer than 2 inches (50 mm) to existing holes.
