FRAME MAINTENANCE - FRAME STRAIGHTENING

1. WARNING: Straightening of front frame rail convolute is prohibited. Failure to follow these instructions may result in personal injury.

When straightening the frame, make sure the following requirements are met:

- CAUTION: Reposition and/or shield any fuel lines, brake lines, or wiring harness or component in the heated area.

If heat is needed to straighten a frame member, keep the temperature below 650° C (1,200° 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 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.
- 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.
