Frame Straightening

MATERIAL SPECIFICATION

Item Specification
Anti-Corrosion Coating PM-12-A -
    WARNING: Straightening of front frame rail convolute is prohibited. Failure to follow these instructions may result in personal injury.
  1. 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 Motorcraft Anti-Corrosion Coating PM12-A.
    • 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.
