Abstract:
1. A pulley removal system used to remove a pulley attached to an end of a crankshaft extending through an engine block, said pulley including a flange nearby said block to provide a restricted space between the engine block and the flange that is accessed during removal of the pulley, said system comprising a hub member, a plurality of puller jaw members adapted to be detachably and radially connected to the hub member, each said jaw member being essentially identical and each jaw member comprising an elongated body having a longitudinal reference line, a substantially flat top surface, and a substantially flat underside surface, said elongated body having first and second opposed ends, said first end being adapted to be attached to the hub member and said second end being free to grasp a flange of a pulley mounted to a crankshaft and including a hooked tip having inner and outer opposed arcuate surfaces that diverge outwardly from a narrow terminal edge, said outer arcuate surface merging with the top surface near said second end and said inner arcuate surface merging with the underside surface near said second end, said body having a thickness that gradually decreases linearly and uniformly from near the first end to near the second end so the flat underside surface inclines towards the hooked tip to form a bite where said underside surface merges with said inner arcuate surface to configure said hooked tip to enable said hooked tip to fit within said restricted space including a plurality of push rods, each rod having a length differing from the other rods and each rod adapted to interact with a crankshaft end of the engine on which the pulley is mounted when the pulley is being removed.
