Screw, wp/imp Pul Puller
Cummins®

A screw is a type of fastener used to join two or more objects together. It has a threaded shank with a head at one end, which can be turned by a tool such as a screwdriver or wrench. A water pump, also known as WP/IMP, is an essential component of the engine cooling system that circulates coolant through the engine block and radiator to dissipate heat. An impeller is located inside the water pump housing and rotates to create suction that draws coolant from the radiator into the engine. A pulley, marked as PUL in automotive jargon, is a wheel with a grooved rim for transmitting power between two rotating shafts using belts or chains. It helps transfer energy from the engine to other components such as alternators and air conditioning compressors. A puller, part number 3823142, is a tool used for removing gears, bearings, pulleys or other parts that are pressed onto shafts or hubs with little clearance between them. It works by applying force evenly around the circumference of the part being removed until it pops off its mount without damaging surrounding components.
