Notes:
168. NEMA 42/48 C-Face, 1/2” diameter keyed shaft, 1-5/16” long 297. 184T Base, 4.5” shaft height
If base is removed, bolt holes must be plugged in order to maintain NEMA Totally-Enclosed standards.
If base bolts are used without base, use a 1/4” thick washer to prevent interference with motor rotation.
