CATERPILLAR-3054-3056-C33-C44-FAN-DRIVE-PULLEY

This fan drive pulley (130-3880) transfers drive from the belt to the cooling fan on Caterpillar's 3054, 3056, C33 and C44 engines. It carries a sealed bearing internally, and because the fan is one of the heavier loads on the accessory drive, wear here shows up faster than on idler pulleys elsewhere in the system — usually as a wobble visible at the fan blade tips when the engine's running. Left unaddressed, that wobble eventually reaches the belt and fan shroud. Orange.net.za ships this part fast across South Africa.
