VQ35DE MODELS

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.

Connect harness connector into pressure sensor securely.

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionNDS000CD
Observe the following precautions when disassembling and servicing drive shaft.

Perform work in a location which is as dust-free as possible.

Before disassembling and servicing, clean the outside of parts.

Prevention of the entry of foreign objects must be taken into account during disassembly of the service
location.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
