Frame Straightening
- 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 (1,202°F) (a dull red glow). A temperature sensitive thermal melt crayon should be used to monitor heat buildup.
- Heat should be kept to a minimum area so that the hardness of the metal is not affected.
- Straightening should only be attempted on frames that fail to meet specifications of the diagonal checking method or where damage is apparent.
- Straightening should be limited to parts which are not severely bent.
- Reposition and/or shield any fuel lines, brake lines, or wiring harnesses or components in heated area.
CAUTION: Reposition and/or shield any fuel lines, brake lines, or wiring harness or component in the heated area.
WARNING:
Straightening of the front frame rail convolute is prohibited. Failure to follow these instructions may result in personal injury.
