When dealing with larger generator feed wires, splices, pins and terminals require special hydraulic crimpers. I'm not an expert at the Standard Wiring Practices Manuals. For me, looking for the proper tooling can be difficult.
As a way to help myself (and others) is to make an entry on every repair and the tooling we used to accomplish the job.
