Cut the studs off the 8G1182 Plate Assemblies at the bottom of the guard. Drill 12.7 mm (.50") holes through the parts of the studs in the brackets.5. Fabricate two spacers as shown in Illustration 3.6. Weld the spacers, fabricated in Step 5, to the 8G1182 Plate Assemblies. Make sure the holes in the spacers are in alignment with the holes which were drilled through the studs. See Illustration 2.7. Put the grill in place on the machine, but turn it 180° (front to back) from its original position. In this position, the louvers will direct the fan discharge up in the air.
