* Scribe matchmarks between the thrust plate and power steering pump housing.

FIGURE 6:

* Loosen thrust plate from pump housing using a 1/4-inch drift punch and a hammer (Figure 6). Do not remove thrust plate from housing.


IMPORTANT

* To prevent the pump ring, rotor and vanes from falling out of the power steering pump housing and thus inhibiting proper reassembly, do not remove the thrust plate until the housing is inverted.

9. Pump assembly from vise, invert and remount into vise with thrust plate facing up.

10. Thrust plate from power steering pump housing.

11. Thrust plate O-ring from power steering pump housing.

IMPORTANT

* Note the pump ring position relative to the power steering pump housing to ease pump reassembly.
