NOTE: Refer to the Exploded View as needed during the
following procedure.
1.
Remove the power steering pump (see page 17-16).
2.
3. Hold the power steering pump (A) in a vise with
soft jaws, hold the pulley (B) with the special tool,
and remove the pulley nut (C) and pulley. Be
careful not to damage the pump housing with the
jaws of the vise.
4. Loosen the flow control valve cap with a hex
wrench, and remove it and the O-ring, flow control
valve and spring.
5. Remove the pump cover and pump cover seal.
6. Remove the outer side plate, pump cam ring, pump
rotor, pump vanes, side plate and O-rings.
7. Remove the snap ring, then remove the subvalve
from the pump housing.
8. Remove the circlip, then remove the pump drive
shaft by tapping the shaft end with the plastic
hammer.
9. Remove the pump seal spacer and pump seal.
10. Check the flow control valve for wear, burrs, and
other damage to the edges of the grooves in the
valve.
11. Inspect the bore of the flow control valve on the
pump housing for scratches and wear.
12. Slip the flow control valve back in the pump
housing, and check that it moves in and out
smoothly. If OK, go to step 13; if not, replace the
pump as an assembly. The flow control valve is not

13. Attach a hose (A) to the end of the flow control
valve (B) as shown. Then submerge the flow
control valve in a container of power steering fluid
or solvent (C), and blow in the hose.
• If air bubbles leak through the valve at less than
98 kPa (1.0 kgf/cm , 14.2 psi), replace the pump
as an assembly. The flow control valve is not
available separately.
• If the flow control valve tests OK, set it aside for
reassembly later.
14. Inspect the ball bearing by rotating the outer race
slowly. If you feel any play (axial or radial) or
roughness remove the faulty ball bearing (A), and
install a new one (B).
15. Inspect each part shown with an asterisk in the
Exploded View; if any of them are worn or
damaged, replace the pump as an assembly.
16. Clean the disassembled parts with solvent, and dry
them with compressed air. Do not dip the rubber
parts in solvent.
17. Align the pin (A) of the subvalve (B) with the oil
passage (C) in the pump housing. Push the
subvalve into place, then install the snap ring (D).
18. Install the new pump seal (A) (with its grooved side
facing in) into the pump housing by hand, then
install the pump seal spacer (B).
19. Position the pump drive shaft (C) in the pump
housing (D), then drive it in using a 29 mm socket
(E).
