Frame Straightening

FRAME STRAIGHTENING

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

- CAUTION: Straightening of the front frame convolute can cause frame degradation and is prohibited.

- Straightening should only be attempted on a frame that fails to meet specifications of the diagonal checking method or where damage is apparent.

- Straightening should be limited to parts which are not severely bent.

- CAUTION: Do not use water to cool the frame after heating. Drenching a hot frame with water causes the frame to become brittle and changes the strength of the frame. Let the frame cool naturally.

If heat is needed to straighten a frame member, keep the temperature below 650°C (1200°F) and at a dull red glow.

- Heat should be kept to a minimum area so that the hardness of the metal will not be affected.
