SUSPENSION CROSSMEMBER REPAIR
This task covers:
General mechanics tool kit:
automotive (Appendix B, Item 1)
Metal strip (Appendix C, Item 50)
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
l-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 psi (482,650 kPa) tensile strength.
Avoid heat build-up in the rubber bushing areas toward the outer
edges of the crossmember.
For welding instructions, refer to TM 9-237.
Center a 15U2-in. (39.4 cm) metal strip (3) between the end brackets (21, flat against bottom edges
of the crossmember (1). Weld metal strip (3) to the crossmember (1).
Spot-paint welded area (TM 43-0139).
