The rotor is mounted on bearings.Both front and rear bearingsare sealed and lubri -cated for life. The alternatoris driven by the crank-shaft pulley with a single belt. The idler, the waterpump and the fan mounted on the water pump pulleyare driven simultaneously by the crankshaft pulleywith an identical matched pairof belts.3 - 1 8 3 .
