I worked for Hyster for 12 years and saw many of the 4.3 engines. Had starter problems, breaking nose cone, or breaking bolts off with only one or two. Biggest cause? Not crappy design, but tech not tightening the bolts up, using other than the starter bolts. Didn't need to add anything. Many of these trucks had 8,000 to 10,000 hours on them without issue. Use correct bolts and tighten correctly, the bracket keeps the starter from miss aligning should the mounting bolts become loose.
