4.Insert the supply pump
assembly through the vacuum pump opening in the timing chain
case
so that the slit on the supply pump gear is aligned with the
oil channel hole on the timing
chain case. 5.Tighten the supply pump mounting bolts to the specified torque. Tightening torque: 25 ± 7 N·m 6.If the supply pump gear mounting nut is loosened, use the same special tools as during removal to tighten the supply pump gear mounting nut to the specified torque.
