Instructions for drilling out a 5/8-11 broken Bradley Tank Skirt bolt in the field with a 1/2" hand drill

1. Remove skirt from side of Bradley (per tech manual)
2. Grind off any excess bolt sticking above the surface that the fixture mounts on (if broken below the surface move to Step 3)
3. Remove 3 to 4 of the 3/4-10 bolts in the straight line pattern
4. If all (5) 5/8-11 skirt bolts are broken, use (2) of the 3/4-10 bolt holes to secure the "Universal Drill Fixture" to the side Bradley (200 combinations) in different locations to finish the remaining (4) broken bolts.
5. Align bushing hole over the 5/8-11 broken bolt.

Alignment tip: When aligning fixture over 5/8-11 (.625 Dia. bolt), use the bushing out of the 3/4-10 tool pack, it's I.D. is 21/32 (.656). This will allow you to align by eye perfectly, tighten the fixture down and IMMEDIATELY PUT THE 3/4- 10 TOOL PACK AWAY. The next bushing size up works with all sizes that you are dealing with.
