The 8N-10145 generator Tensioning Arm bolts to the governor and the generator support bracket. I have a dozen or so OEM arms if you need one. This is used on the early 8N's with front mount distributor only. Fan Belt tension is vital to charging the generator/electrical system/battery -without tension you are flogging a dead horse. The side mount dist introduction revamped the gen and moved it to the LH side of engine and it had its own tensioning bracket.
