Fan drive pulley 02/201357 Perkins, aftermarket

Fan drive pulley 02/201357 is an aftermarket part for the Perkins engine.

The fan drive is a bearing housing and flange, turned by the belt and carrying the cooling fan. When the bearing wears, the unit hums, the fan wobbles and the blades can strike the cowl. A seized bearing can break the belt and overheat the engine. The fan drive is part of the belt drive: its pulley is turned from the crank pulley by the belt. Fan speed follows engine speed, and the unit's bearing carries both the belt tension and the weight of the fan. Imbalance on the fan side shortens bearing life, so a fan with a broken blade must be replaced at once. The unit housing bolts to the front of the engine. The bearing is a sealed type. The unit has a cast housing. The unit is supplied new. The unit mounts on the front of the engine.
