e. Reassembly.
(1) Press the inner bearing (12) and spacer (13) in the pump body (9).
(2) Press the oil seal (14) into the oil pump body (9), making sure that the pressing tool is resting against the
outside diameter of the oil seal. The oil seal (14) must be installed in the pump body (9) with the sealing lip
facing the outer bearing (18).
(3) Press the outer bearing (18) on the shaft (15), making sure that the bearing driver tool is resting against the
inner race of the bearing.
(4) Install the assembled shaft (15) in the bracket (11). Install the retaining ring (17).
(5) Install the pump body (9) and gasket (10) and tighten the bolts (8).
(6) Push the rotor (7) on the splined end of the shaft (15).
(7) Install the vanes (20) and see that the radius edge of each vane is facing the ring (6).
(8) Install the seal ring (5) on the pump body (9) and position the ring (6) so that the holes in the ring are
properly alined with the pins (19) in the pump body.
(9) Attach the ring (6) to the pump body (9) and install the seal ring (5) and pressure plate (4).
(10) Install the plate spring (3) and press the cover (2) against the pump body (9).
(11) Install the cover screws (1). Rotate the pump shaft (15) by hand and gradually tighten the cover screws (1)
