2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector.

Insert clip so that protrusion (G) of fuel injector matches cut-
out (D) of clip.
CAUTION:

Never reuse clip. Replace it with a new one.

Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.

Insert it while matching it to the axial center.

Insert fuel injector so that protrusion (B) of fuel tube matches
cut-out (C) of clip.

Make sure that fuel tube flange (A) is securely fixed in flange
fixing groove (E) on clip.
c. Make sure that installation is complete by making sure that fuel
injector does not rotate or come off.
3. Set fuel tube and fuel injector assembly at its position for installation on cylinder head.
CAUTION:
For installation, be careful not to interfere with fuel injector nozzle.

19. Fully lift up lever (A), and push the slack guide (B) into the inside
of chain tensioner (for oil pump) (1).

The slack guide is released by fully lifting the lever up. As the
result, the slack guide can be moved.
20. Matching the hole on lever with the hole on tensioner body,
insert a stopper pin (C) to secure slack guide.
NOTE:
Use approximately 1.0 mm (0.04 in) diameter. hard metal pin as
a stopper pin.
21. Remove chain tensioner (for oil pump).

When the holes on lever and tensioner body cannot be aligned, align these holes by slightly moving the
slack guide.
22. Hold the WAF part of oil pump shaft (A), and then loosen the oil pump sprocket bolt and remove them.
CAUTION:

Secure the oil pump shaft with the WAF part.

Never loosen the oil pump sprocket bolt by tightening the
oil pump drive chain.

*: There are 2 outer grooves in camshaft sprocket (INT). The
wider one is a matching mark.

If these matching marks are not aligned, rotate the camshaft
slightly by holding the hexagonal portion to correct the posi-
tion.
