Frame Straightening
WARNING:
- Straightening of front frame rail convolute is prohibited.
- 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 See UNDERBODY MISALIGNMENT INSPECTION .
- Straightening should be limited to parts which are not severely bent.
