Frame Straightening

FRAME STRAIGHTENING

1. WARNING:
- Straightening of front frame rail convolute is prohibited. Failure to follow these instructions may result in personal injury.
- Do not use an A, B or C fire extinguisher to extinguish magnesium fires. Use only a type D fire extinguisher to extinguish magnesium fires. Failure to follow these instructions may result in personal injury.
- Do not use water to extinguish magnesium fires. Water will excite a magnesium fire. Failure to follow these instructions may result in personal injury.

CAUTION: Magnesium will burn if heated above800°F.

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.

NOTE: Whenever factory E-coat has been removed by sanding, grinding or weld burn-off, the coating must be restored. Use low temperature anti-corrosion coating.

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.
