CAUTION:

Before 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.

piston heads.

When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.

14. Using the sprocket holder (special service tool), hold fuel pump
sprocket to prevent falling.

For sprocket holder, use KV11106060 machined as shown in
the figure, because the previous bore is not fitting.

When the sprocket holder is installed, if the positioning stop-
per pin (special service tool) interferes, pull out the positioning
stopper pin approximately 10 mm (0.39 in), then install it.

After the sprocket holder is installed temporarily, tighten the
sprocket holder after making extension bar and TORX socket
(size: E10) insert into the machined bore.

The length of the sprocket holder mounting bolts should be
approximately 15 mm (0.59 in) (M6 thread length).

Make 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 (special service tool) until fuel pump is installed.

After the sprocket holder is installed, pull out the positioning
stopper pin from fuel pump sprocket.

INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
timing chain if necessary.
INSTALLATION
1. Install new oil seal to spacer.
2. Install spacer to fuel pump.
3. Install coupling to fuel pump of spacer.

Using the TORX wrench (special service tool), tighten the
sprocket nut to fix the coupling.
4. Install adjust shim.

For shim adjustment, measure dimension L [Distance
between front surface of coupling and the fuel pump flange
(spacer)] at two opposing points near the coupling bolt center.
Use the average of these two measurements to select the
shim grade that marked on adjust shim.

The shim adjustment is required only when the fuel pump is
replaced.
