ineed 420A harmonic installer 1.75 thread
Anyone have a clue about 420A harmonic pulley .. INSTALLER tool? 1.75 thread.. realy long bolt with a nut and a bearing to press it into crankshaft
well, first off its just an accesory pulley, its not a harmonic balancer...as for the bolt to press it on...just use the crank bolt...it will press it on as its tightened down...however throwing the pulley in the oven for 1/2 hr at 500 degrees makes it go on a bit easier
