Adjustment Procedure
1. Position the No.1 cylinder to BTDC 30° .
2. Remove the chain tensioner.
3. Remove the exhaust camshaft sprocket.
4. Align the intake and exhaust camshaft flange hole with the cylinder head upper surface.
Intake Side : 3 o ’clock direction
Exhaust Side : 9 o ’clock direction
5. Secure the intake and exhaust camshaft.
6. Position the piston of No.1 cylinder at TDC (OT) by turning the crankshaft.
7. Turn the camshaft adjuster of the intake camshaft to the left as much as possible (cam adjuster ‘retarded ’ position).
8. Install the chain to the intake camshaft sprocket.
Notice
Timing chain must be placed on the guide rail in gear case
cover.

Inspection
1. Position the No.1 cylinder piston to TDC (OT) by turning the crankshaft. Notice When the OT mark on vibration damper is aligned with timing
gear case cover, the intake and exhaust cam of cylinderwill make the slope to the center and will face up. In this
way, the adjustment hole of the intake and exhaust camshaft will match in line with the cylinder head upper end, at 3
o’clock, and 9 o ’clock direction each other.
2. Check the timing as below procedure; - Check if the camshaft adjustment hole is positioned to 3 o’clock direction at the intake side and to 9 o ’clock
direction at the exhaust side, respectively and align withthe cylinder head mating surface.
- At this condition, check if the OT mark on vibration damper aligns with the marker on the timing gear case.

11. Check the camshaft timing.The sprocket bolt is designed to be used only once, so replace with new one.
10. Install the chain tensioner.

1. Place the supporting bar (12) and the slide (9) at thecamshaft bearing cap (Nos 1 & 7/8&14) and tighten them with the bearing cap bolt. 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

Remove the valve spring only at TDC.
Always 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. Supporting Bar 111 589 01 59 00

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.

M162 ENGINE MECHANICAL 1B1-73
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
