Removal and InstallationAGS000HG

Refer to PS-41, "Components" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

Confirm with mating marking that if it is in phase with hose and
clamp, then correct if needs.

To install eye joint, join projection of eye joint into notch of power
steering pump, and attach eye joint to power steering pump
properly. Then, tighten eye bolt by hands fully, and tighten it with
a specified torque.
