A stud passes through the PAS pump and through a flanged bush in the auxiliary housing, the auxiliary housing and PAS pump are secured by a nut. As the two bolts and nut are tightened the bushes move slightly and the flange of each bush clamps the PAS pump. A drive pulley is attached to the pump drive shaft with three bolts, and is belt driven at a ratio of 1.4 crankshaft revolutions to 1 of the drive pulley. Fluid is drawn into the PAS pump inlet from the reservoir through a flexible hose at low (suction) pressure. Fluid at high pressure from the PAS pump outlet is supplied to the rotary control valve on the steering box.
