Measure resistance between the injector terminals 1 and 2.
4.
Check that the resistance is within the specification.
Specification: Refer to “Specification”
Removal
In case of removing the high pressure fuel pump, high
pressure fuel pipe, delivery pipe, and injector, there may be injury
caused by leakage of the high pressure fuel. So don’t do any repair
work right after engine stops.
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Release the residual pressure in fuel line (Refer to the Fuel
Delivery System - Repair Procedures - "Release Residual Pressure in
Fuel Line").
When removing the fuel pump relay, a Diagnostic Trouble Code
(DTC) may occur. Delete the code with the GDS after completion of
“Release Residual Pressure in Fuel Line” work.
3.
Remove the delivery pipe & injector assembly (Refer to "Delivery Pipe" in this group).
4.
Remove the retaining clip (A), and then separate the injector from the delivery pipe.
Installation
Do not reuse the injector retaining clip, O-ring, backup
ring, washer seal or combustion sealring. Once an injector is removed,
the five components must be replaced with new ones.
1)
Combustion seal
2)
Washer seal
3)
Backup ring
4)
O-ring
5)
Retaining clip
•
Item 1,3 and 4 are supplied in a single kit.
•
Install the component with the specified torques.
•
Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
•
Apply engine oil to the injector O-ring.
•
Do not reuse the delivery pipe mounting bolts. Once the delivery pipe is removed, the boltsmust be replaced with new ones.
•
When inserting the injector, be careful not to damage the injector tip.
•
When replacing the washer seal, the steal plate (A) part
should be faced the cylinder installation part and the rubber plate (B)
part should be faced the injector body part.
•
Do not reuse the combustion seal.
•
Be careful not to apply engine oil on the combustion seal ring.
•
Avoid dropping the fuel pipe (including injectors) or bumping
it into any hard objects sincedamage to the internal components may
occur. If necessary, visually inspect and confirmproper operation with
performance tests prior to reuse.
•
Before installing the injector into the cylinder head, clean
the injector hole and avoidcontaminants from entering inside the
injector hole. When installing the injector, avoid bumpingthe injector
tip into any of the surrounding components since the tip may become
damagedfrom the impact.
•
When fastening the three fuel delivery pipemounting bolts, fully hand-tighten first, andthen tighten in the proper sequence ( > > )
in several cycles up tothe specified torque. The delivery pipeshould
move less than 1/8 inch (approx.3mm), whenever each bolt is tightened.
1.
Installation is reverse of removal.
Replacement
The injector combustion seal should be replaced new one to prevent leakage after removing the injector.
1.
Remove the combustion seal (A) with a wire cutter.
Grip the sealing ring carefully, pull it to form a small loop and then cut it.
Be careful not to damage the surface of the valve sleeve with the wire cutter.
2.
Before the assembly of the sealing ring the groove must be cleaned using a clean cloth.
Any coking of the injector sealing surface must be carefully removed with a brass-wire brush.
The surfaces of the new sealing ring must be clean and free of grease.
3.
Place the combustion seal on the coneand pull downward on the seal as indicatedin the photo.
Your fingers will work better forinstalling the Combustion Seal overthe cone.
4.
Pull the seal downward until it is near thebottom of the cone as shown in the photo.
5.
Place the cone (with seal) on the end ofthe injector.
Place the sizing tool (SST No.: 09353-2B000) overthe cone. Make sure the tool flange istoward the seal as shown.
Press down on the tool to work the sealover the injector and into the groove.
6.
Because the seal will stretch as it goesover the end of the injector, it will be a bitoversized after installation.
By letting the injector and seal set for a fewminutes, the seal may reduce in size.
Inspect the seal for damage before continuing.
7.
Place the resizing tool (flange up) over theseal. Twist the
tool slightly while pushingdown over the seal. This should reduce
thesize of the seal.
Be careful not to apply engine oil on thecombustion seal ring.
8.
Place injector into the head as shown.
9.
Twist slightly while pressing the injectorinto position in the head.
This should complete the resizing of theseal.
Remove the injector and inspect the sealbefore completing the injector installation process.
10.
If the injector comes with a protective steelwasher held in
place by a spring clip; bothwill have to be removed before installation.
11.
Install the Washer Seal onto injector withthe rubber side (stepped) toward theinjector.
12.
The stepped rubber side of the seal goes towards the injector.
13.
The flat washer side of the seal goes towards the head.
