Precautions for models with SRS air bag and pre-tensioner seat beltEGS00048
WAR NIN G:
lBefore removing and installing components and harnesses of SRS air bag and seat belt pre-ten-
sioner system, turn ignition switch OFF, disconnect battery ground cable, and wait at least 3 min-
utes. (This discharges electricity held in the air bag sensor unit's additional power circuit.)
lDo not use pneumatic or electric tools to remove and install the components.
lDo not solder SRS air bag and seat belt pre-tensioner system harnesses when making repairs.
Make sure harness is not pinched and there is no contact with other components.
lWhen checking the SRS air bag and the seat belt pre-tensioner circuit or the components of each
system, do not use an electric tester such as a circuit tester. (This is to prevent accidental trigger-
ing caused by the weak electric current of a tester.)
lNever insert foreign material (such as a screwdriver) in the air bag module and pre-tensioner seat
belt connectors. (The units may be actuated by mistake by static electricity.)
lSeat belt pre-tensioner and SRS air bag harnesses can be distinguished from other harnesses by
their yellow connectors.
lWhen servicing, refer to “SB Seat Belt” and “SRS Air Bag” for safety.
CautionEGS00049
lAlways follow the warnings and the cautions below in disassembly procedures:
–Work in a clean, dust-free place. No dust proof device is necessary.
–Clean outside of unit before disassembly.
–Clean parts to be disassembled. Be careful not to allow any dirt or other foreign materials to enter or con-
tact with parts.
–Assemble disassembled parts properly, following order shown in manual. If work has been suspended in
the middle of assembly, place a clean cover over parts. This will prevent them from being contaminated.
–Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on
cleaned parts that might affect operation of parts.
–Clean disassembled parts (except rubber parts) with kerosene. Drain oil by blowing with air or absorbing
with shop papers.
–Before assembling, apply Nissan power steering fluid to O-rings and seals.
–Replace gaskets and O-rings with new ones. Be careful not to damage any O-rings, oil seals, and gaskets
during assembly.
lIf following part is scratched after disassembly of steering pump, replace applicable part: case, rear body,
side plate, pulley, rotor, vane, or flow control valve
lMark source of fluid leak with a white marker for identification.
lSeals and copper washers must not be reused.

8. Check that boot installation length “L” is the length indicated
below. Insert a flat-bladed screwdriver or similar tool into smaller
side of boot. Remove air from boot to prevent boot deformation.
CAUTION:
lBoot may break if boot installation length is less than
standard value.
lBe careful that screwdriver tip does not contact inside
surface of boot.
9. Secure big and small ends of boot with new boot bands as
shown in figure.
CAUTION:
Rotate housing and check that boot installation position
does not change. If position changes, reinstall boot bands.

1. Use a drift to press-fit sensor rotor into joint sub-assembly.
CAUTION:
Discard the old sensor rotor; replace with a new one.
2. Wind serrated part of drive shaft with tape. Install boot band and
boot to shaft. Be careful not to damage boot.
CAUTION:
Discard the old boot band and boot; replace with new ones.
3. Remove protective tape wound around serrated part of shaft.Boot installation length
