Installation Notice
2. Turn the crankshaft to position the each cylinder piston at
TDC.
5. Install the engine lock to the ring gear to prevent the
crankshaft from rotating.
6. Blow up with compressed air.Notice
lRemove the valve spring only at TDC.
lAlways rotate the crankshaft by holding the chain to
prevent from timing chain damage and tangling, and for
smooth rotation.
3. Remove the valve tappet (1) using the magnetic finger.
4. Install the leakage tester connecting hose to the spark plug
hole.

9. Mount the thrust piece (8) vertically to the valve spring
retainer (3).
10. Make the thrust piece (8) and the slide (9) perpendicular
to each other.
11. Secure the slide (9) by turning the adjust bolt (10).
12. Press the valve spring (4) by using the lever pusher (11).
14. Remove the upper retainer (3) and the valve spring (4).
15. Remove the valve stem seal and replace if necessary.
Notice
Check the valve stem seal and replace if necessary.
16. Remove the lower retainer (6).
Notice
Check the retainer for damages and replace with a new
one if necessary.
17. Installation should follow the removal procedure in the
reverse order.

CHAIN TENSIONER
1 Screw Plug................................................ 40 Nm
2 Seal
3 Filler Pin
4 Compression Spring5 Snap Ring
6 Thrust Pin
7 Chain Tensioner Housing.....................72-88 Nm
8 Seal
Removal Procedure
1. Position the number 1 cylinder to ATDC 20°.
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.
Notice
In 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 snap ring doesn’t return to
the original position and the tension gets excedded.

1B2-78 M161 ENGINE MECHANICAL
Installation Procedure
1. Connect the thrust pin (6) and the snap ring (5) to the chain
tensioner 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
lFor the removal of screw plug, be careful that it can be
jumped out due to the force of compression spring.
lRemove 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).
