Note: All directions of rotation mentioned in the text are assumed to be viewed from the front of the engine.
1. Remove the front right wheel.
2. Remove the front right fender liner.
3. Drain the engine oil.
Caution: Drain the engine oil only after the engine has cooled down.
4. Remove the following parts:
- Intake manifold.
- Cylinder head cover.
- Attachment drive belt.
5. Set the piston of the first cylinder to the top dead center position of the compression stroke:
Turn the crankshaft pulley (1) clockwise until the TDC mark (no color) (B) is aligned with the indicator (A) on the front cover.
Note: The white mark (C) is not used in this procedure.
Make sure that the camshaft lobes of the intake and exhaust camshafts, which belong to the first cylinder of the engine, are directed upward and inward (in the direction of the measuring arrows in the figure).
1. Intake camshaft
2. Exhaust camshaft.
The white arrow points towards the front of the car.
If the cams are not pointing in the direction shown, rotate the crankshaft pulley one revolution (360°) and align the marks again in the manner described above.
6. Remove the crankshaft pulley:
Secure the crankshaft pulley (1) with the lock (A) and unscrew the bolt from the pulley by 10 mm.
Note: Do not remove the crankshaft pulley bolt completely as it will be needed as a pivot point for the pulley puller (KV11103000).
Install the pulley puller (A) (KUP 103000) into the threaded holes MB in the pulley (1) and remove the crankshaft pulley
7. Remove the rear engine thrust rod.
8. Support the underside of the engine with a transmission jack, then remove the mounting stands and the right engine mounting insulator.
9. Remove the lower oil pan.
Note: If you do not plan to remove the crankshaft sprocket and balancer assembly components, this step is not necessary.
10. Remove the electromagnetic valve for supplying oil to the intake valve advance control system.
11. Remove the automatic tensioner of the accessory drive belt.
12. Remove the front engine cover:
Loosen the mounting bolts in the reverse order to that shown in the figure.

Separate the parts by inserting a sealant knife into the places indicated by arrows in the figure, and then remove the front cover,
Attention.
- Be careful not to damage the contact surfaces.
- In some places the sealant is applied to meet specific operational needs and does not need to be removed, so the sealant needs to be cut only at the points shown in the figure.
13. Use a screwdriver to remove the front oil seal from the front cover.
Caution: Be careful not to damage the front cover.
14. Remove the timing chain tensioner:
- Press the plunger of the timing chain tensioner.
- Insert the locking pin (A) into the hole in the housing and lock the plunger in the depressed position.
Note: Use a hard metal rod with a diameter of about 1.5 mm.
Remove the timing chain tensioner (1).
15. Remove the tensioner guide (2), damper (3) and drive chain (1).
Caution. Do not rotate the crankshaft and camshafts separately from each other with the timing chain removed. This may cause the pistons to come into contact with the valves and, as a result, damage them.
16. Remove the crankshaft sprocket and balancer block drive components:
Raise the lever (A) fully and press the drive chain guide (B) into the balancer block drive chain tensioner (1).
Note: The drive chain guide is unlocked when the lever is fully raised, allowing it to be moved.
Align the hole in the lever with the hole in the tensioner housing and insert the locking pin (C) to secure the guide.
Note: Use a hard metal rod with a diameter of approximately 1.0 mm as a locking pin.
Remove the balancer block drive chain tensioner.
Note: If the holes in the tensioner lever and housing do not match, align them by slightly moving the chain guide.
Holding the cylindrical part (A) of the balance shaft (width of cylindrical part: 19.0 mm), unscrew the balance shaft sprocket bolt.
1. Upper oil pan. Arrow indicates the front side of the engine.
Remove the crankshaft sprocket, sprocket and balancer drive chain as one set.
17. Remove the timing chain guide from the front cover if necessary.
