The corner adapters are located under the side bars in several configurations. Placement of the new adapter may require some latitude of adjustment. Make a 6.0 mm (0.24 inch) bevel weld to the top of the adapters, to the bottom of the adapters, and to the side bars. The location of some corner adapters may be too close to the edge of the side bars or the base edges. This may prevent you from applying a full 8.0 mm (0.32 inch) fillet weld. Apply as much fillet weld as possible in order to protect the bevel welds. Illustration 11 and illustration 12 show the DRS230 adapters after you have applied the weld. You have replaced the 8J-7525 Adapters with the new DRS230 adapters. Illustration 13 shows the DRS230 adapters after you have applied the weld. You have replaced the J200 adapterswith the new DRS230 adapters. Illustration 14 shows the DRS230 adapters after you have applied the weld. You have replaced the DRS200 adapter with the new DRS230 adapters.You will need to alter the position of the new DRS230 adapters because the top straps and the bottom straps of the new adapters are wider than the top straps and the bottom straps of the former adapters. Due to the slightly greater width of the straps on the new DRS230 adapters, be careful to properly locate the center adapters at all of the inboard positions.

Refer to illustration 16. Slide the adapter onto the bottom edge until hard contact occurs between the adapter and the angled portion of the base edge at point (1).
Illustration 17 g01103817
Refer to illustration 17. Start the first weld bead at the front of the top strap at the root of the bevel groove. Make one continuous pass to the center of the back of the adapter. Do not stop at the corners of the adapter.
Illustration 18 g01103821
Refer to illustration 18. Move to the other side of the top strap. Start the second weld at the front of the top strap at the root of the bevel groove. Make one continuous pass to the center of the back of the adapter. Do not stop at the corners of the adapter.
Return to the first weld. Make another weld from the front of the top strap to the center of back of the adapter. The interpass temperature must not exceed 260 °C (500.0 °F).
Continue to make welds to alternate sides of the adapter until you fill the bevel groove.
