CAUTION:
Be careful not to allow leaked fuel to contaminate engine
room. Especially, ensure to keep engine mounting insulator
clear of fuel.
6. Remove nozzle oil seal.
lUsing the flat-bladed screwdriver, pry flange to remove oil
seal.
NOTE:
Nozzle oil seal seals between fuel injector and rocker cover. If
only injection tube shall be removed and installed, nozzle oil
seal replacement is not required.
7. Remove rocker cover. Refer toEM-56, "
ROCKER COVER".
8. Remove spill tube mounting bolts and nut.
lLoosen bolts and nut to the reverse order in the figure and
remove them.
CAUTION:
When loosening nut, fix spill tube retaining bolt with span-
ner.

9. Install remaining parts in the reverse order of removal.
INSPECTION AFTER INSTALLATION
lInput “INJECTOR ADJUSTMENT VALUE” to ECM after installing to the vehicle when replacing fuel injec-
tor. Refer toEC-25, "
Injector Adjustment Value Registration".
Example: Injector Adjustment value = D021ABCD1A061234000000000000E6
lStart engine and increase engine speed to check for fuel leak.
CAUTION:
Do not touch engine immediately after stopped as engine becomes extremely hot.
A. Align paint mark B. Insert the hose up to 26 mm (1.02 in) C. Insert the hose up to 28 mm (1.10 in)
D. To fuel cooler (under floor)

Removal and InstallationEBS01E64
CAUTION:
lBefore removing and installing fuel pump, be sure to remove sprocket. Do not loosen or remove
installation nut in the center of fuel pump. If loosened or removed, replace fuel pump.
lAfter removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
lWhen installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.
lWhen fuel pump is replaced with new one or another one, perform fuel pump leaning value clean-
ing before starting engine. Refer toEC-24, "
Fuel Pump Learning Value Clearing".

2. Remove fuel hose and spill hose from fuel pump. Refer toEM-44, "INJECTION TUBE AND FUEL INJEC-
TOR".
CAUTION:
Be careful not to spill fuel in the engine component.
3. Disconnect harness connectors from fuel pump.

6. Hold fuel pump sprocket and remove bolt.
a. Insert the positioning stopper pin [SST] into the hole 6 mm (0.24
in) in the diameter on the fuel pump sprocket.
b. Using the TORX wrench [SST], turn pump shaft little by little to
adjust the position of fuel pump sprocket so that the holes align.
c. Push the positioning stopper pin [SST] through fuel pump
sprocket to fuel pump body to hold fuel pump sprocket.
lInsert the positioning stopper pin until its flange contacts the fuel
pump sprocket.

8. Using the sprocket holder [SST], hold fuel pump sprocket to pre-
vent falling.
lFor sprocket holder, use KV11106060 machined as shown in
the figure, because the previous bore is not fitting.
lWhen the sprocket holder is installed, if the positioning stop-
per pin [SST] interferes, pull out the positioning stopper pin
approximately 10 mm (0.39 in), then install it.
lAfter the sprocket holder is installed temporarily, tighten the
sprocket holder after making extension bar and TORX socket
(size: E10) (commercial service tool) insert into the machined
bore.
lThe length of the sprocket holder mounting bolts should be
approximately 15 mm (0.59 in) (M6 thread length).
lMake sure that the a- and b-faces of the sprocket holder con-
tact the bottom side of the sprocket (small diameter side).
CAUTION:
Do not remove the sprocket holder [SST] until fuel pump is installed.
lAfter the sprocket holder is installed, pull out the positioning
stopper pin from fuel pump sprocket.
9. Using the extension bar and the TORX socket (size: E10) (com-
mercial service tool), remove the tightening bolts.
CAUTION:
Do not disassemble or adjust fuel pump.
10. Remove the fuel pump toward the rear of engine.
CAUTION:
For removal, be careful not to drop the seal washer into the engine.
NOTE:
The seal washer of the tightening bolts cannot be reused.
11. Remove adjusting shim.
12. Attach a suitable tool in the M8 bolt hole on coupling.
