Checking Drive BeltsINFOID:0000000001702475
WARNING:
Be sure to perform this step when the engine is stopped.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000001702476
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000001702477
REMOVAL
1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
CAUTION:

the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6
mm (0.24 in) in diameter into the hole (B) of the retaining boss to
fix drive belt auto-tensioner.
3. Remove drive belt.

Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6
mm (0.24 in) in diameter into the hole (B) of retaining boss to fix
drive belt auto-tensioner.
3. Install drive belt.
CAUTION:
• Confirm drive belt is completely set to pulleys.
• Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-13, "
Checking Drive Belts".

FUEL INJECTOR AND FUEL TUBE
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.
4. Tighten bolts in numerical order as shown.
5. Installation of the remaining components is in the reverse order of removal.

19. Press stopper tab (A) in the direction shown to push the timing
chain slack guide (B) toward timing chain tensioner (for oil
pump) (1).
• The slack guide (B) is released by pressing the stopper tab
(A). As a result, the slack guide (B) can be moved.
20. Insert stopper pin (D) into tensioner body hole (C) to secure tim-
ing chain slack guide (B).
NOTE:
Use a hard metal pin with a diameter of approximately 1.2 mm
(0.047 in) as a stopper pin.
21. Remove timing chain tensioner (for oil pump).
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.
23. Remove crankshaft sprocket, oil pump sprocket and oil pump drive chain as a set.
24. Remove timing chain tension guide (front cover side) from front cover if necessary.
