Removal Procedure
1. Position the No.1 cylinder to TDC (OT). Notice Remove the oil filler cap at adjustment position, and check whether the intake camshaft cam ’s lobe (arrow) stays in the
upper side.
2. Cover the alternator with a clean cloth.
3. Release the tension by unscrewing the screw plug once.
NoticeIn case that the tension is reduced by unscrewing the screw
plug, reinstall after completely removing the chain tensioner.If the chain tensioner is tightened again without completely reducing its tension, then the detent spring doesn ’t return
to the original position and the tension gets excedded.

Installation Procedure
1. Connect the thrust pin (6) and the snap ring (5) to the chaintensioner housing (7). Notice When connecting the thrust pin, push in the thrust pin far enough so that it doesn ’t protrude at the chain tensioner
housing.
4. Carefully unscrew the screw plug (1), and remove the seal
(2). Notice
For the removal of screw plug, be careful that it can be
jumped out due to the force of compression spring.
Remove the screw plug only when the seal and
compression spring are damaged.
5. Carefully remove the filler pin (3), compression spring (4), snap ring (5), and the thrust pin (6).
6. Remove the chain tensioner housing (7) and the seal (8).
3. Insert the compression spring (4) with the filler pin (3) into chain tensioner housing.
2. Install the chain tensioner housing (7), thrust pin (6), snap
ring (5), and the seal (8). Installation Notice
Tightening Torque 35 - 40 Nm

1. Position the No.1 cylinder to TDC (OT).
4. Mount the wedges to both sides of the camshaft sprocketas shown in the figure.
2 . Insert the
4mm pin to the intake and exhaust camshaft
flange not to rotate camshaft.
3. Remove the chain tensioner.
5. Cover the chain housing with a clean cloth, and grind off the timing chain pin from the intake camshaft sprocket with
the grinder.

7. Connect the new timing chain (2) to the used timing chain(3) with the link (5), center plate (6, thickness 1.6mm), and the outer plate (7).
8. Rotate the crankshaft in the direction if engine revolution by pressing the new timing chain against the exhaustcamshaft sprocket to prevent it to be tangled. Notice Be sure to remove the wedge before cranking the engine.
9. Take out the used timing chain out from the chain housing.
10. Connect both separators of the new timing chain with the link (5) and the center plate (6).
6. Remove the outer plate (7) with the screw driver and
remove the link (5).
11. Install the jaw (a) and the thrust piece (b) to the assembly tool as shown in the figures.

15. Replace the thrust piece (b) as shown in the figure.
13. Install the assembly tool above the link and tighten the
spindle (c) until a block is felt.
14. Place the assembly tool.
12. Place the outer plate (7, thickness 1.2mm) inside the thrust
piece (b).
16. Install the assembly tool to the link pin and tighten the spindle (c).

Removal & Installation Procedure
1. Put the assembly mark at the camshaft sprocket and the timing chain with the paint (arrow).
2. Remove the exhaust camshaft sprocket.
3. Remove the tensioning rail (1) from the tensioning rail pin (3). Notice
Replace the plastic guide (2) if it is damaged.
For installation, exactly align the plastic guide (2) with the tensioning rail (1).
4. Installation should follow the removal procedure in the reverse order.
5. Check the camshaft timing position.
