    Default sleeve it

    Wirefeeder, assuming you are sectioning this frame in a more or less straight and flat area.....I would cut it at approximately 30 deg and install a sleeve at least the same thickness material . The length would be twice the height of the frame rail involved as long as you have clearance to fit . Rosette weld/spot weld minimum four spots per side of each rail plus leave about 1/8 gap between rails with a bevel on rails to make full penetration with sleeve when fully welded together. This method has been done in our shop successfully. Also if its a late model vehicle you might have to check with your DOT about VIN numbers etc. If its an older vehicle Weld On
    Hope this helps Jim uhohjim1@aol.com

    [QUOTE=billie-t;23739]i did a mack truck one time..the owner said he went to mac truck and asked them ..this is what he had me do...cut on 30 degree angle..weld all around and then grind the outside flush..he had ordered another C channel from Mack to fit over the original frame...stuck by `18 inches each side...six bolts on each side...no welding on this piece allowed..
    the top flange of the channel was allowed to be notched for any obstructions caused by the original frame but not the bottom flange...anything here had to be removed and put back on the new bottom flange[/Q




    billie-t, you are right on target with your reply.
    This is the method that we have followed as instructed by several vehicle manufacturers. The bolts should also be a minimum of 5/8" diameter with a shank where it goes through the frame and grade 8 also. Dave

    The only problem with that repair is it cant be done on a box frame..its a C channel frame repair.......but it is the way to go on a semi or other heavy duty truck
