- Drain the remaining fluid from the power steering pump (see «FLUID REPLACEMENT»(ref-372406-S21196568952010092500000) ).
- Hold the power steering pump (A) in a vise with soft jaws (B), then hold the pulley (C) with the pulley holder (D), and remove the pulley nut (E) and pulley. Be careful not to damage the pump housing with the jaws of a vise.
- Remove the inlet joint and the O-ring.
- Loosen the flow control valve cap with a hex wrench, and remove the cap, the O-ring, the spring, and the flow control valve.
- Remove the pump cover and the pump cover seal.
- Remove the outer side plate, the cam ring, the rotor, the vanes, the side plate, and the O-rings.
- Remove the snap ring, then remove the subvalve from the pump housing.
- Remove the 40 mm internal snap ring, then remove the driveshaft by tapping the shaft end with a soft face hammer.
