Frame Straightening

WARNING: Straightening of front frame rail convolute is prohibited.
  1. When straightening the frame, make sure the following requirements are met:
    • If heat is needed to straighten a frame member, keep the temperature below 650°C (1200°F) (a dull Red glow).
    • Heat should be kept to a minimum area so that the hardness of the metal will not be affected.
    • Straightening should only be attempted on frames that fail to meet specifications of the diagonal checking method or where damage is apparent. See BODY MISALIGNMENT INSPECTION  and UNDERBODY MISALIGNMENT INSPECTION  .
    • Straightening should be limited to parts which are not severely bent.
