Visually inspect the main frame rails for damage or distortion. Vehicles with damaged frame rails
should be sent to GS maintenance for repair.
Crossmember with end bracket weld breaks of more than 1 in. (2.54
cm) must be replaced. Any crack or tear in the crossmember longer
than 1-3/4 in. (4.4 cm) requires replacement of the crossmember.
Inspect the crossmember (1) for bends, cracks, or broken end bracket welds. Bent crossmembers (1)
should be straightened. Small cracks or tears should be stop-drilled and welded.
Heli-Arc, MIG, or TIG welding equipment may be used, provided
the electrode used has a 70,000 (482,650 kPa) psi tensile strength.
Avoid heat buildup in the rubber bushing areas toward the outer
edges of the crossmember.
For welding instruction refer to TC 9-237.
Center a 15-1/2-in. (39.4 cm) metal strip (3) between the end brackets (2), flat against bottom edges
of the crossmember (1). Weld the metal strip (3) to the crossmember (1).
Spot paint welded area. (Refer to TM 43-0139).
