Due to the increased load on the crankshaft by the supercharger, oil pump alignment is critical for proper pump operation and service life. The oil pump must be centered on the crankshaft in order to work correctly. EN-48036 fits over the crankshaft, and centers the oil pump to the crankshaft, allowing the retaining bolts to be torqued to the service information specification. Improper installation methods will reduce the life of or cause damage to the oil pump.
