REMOVAL SERVICE POINTS

<<A>> CAMSHAFT SPROCKET REMOVAL

CAUTION

Never turn the crankshaft anti-clockwise.

1. Turn the crankshaft clockwise, align the timing

marks on the camshaft sprocket to set No.1
cylinder to TDC of its compression stroke.

2. Remove the timing belt under cover rubber plug

and then set special tool adjusting bolt
(MD998738).

3. Screw in the special tool until it comes in contact

with the timing belt tensioner arm.

4. Secure the camshaft sprocket and valve timing

belt with wiring bands and so on to prevent
slippage between the camshaft sprocket and
valve timing belt.

5. Use the following special tools to hold the

camshaft sprocket.

•

Front hub and flange yoke holder (MB990767)

•

Pin (MD998719)

CAUTION

Do not rotate the crankshaft after camshaft
sprocket removal.
6. Remove the camshaft sprocket with the valve

timing belt and place it on the timing belt lower
cover.

DISCONNECTION

Make mating marks on the radiator upper hose and
the hose clamp. Disconnect the radiator upper hose.

<<C>> FUEL HIGH-PRESSURE HOSE REMOVAL

1. Remove the fuel high-pressure hose stopper.

2. Remove the fuel high-pressure hose in the

direction shown in the figure while the retainer is
pulled up.
NOTE: If the retainer is released, install it after
removing the fuel high-pressure hose.

<<D>> CYLINDER HEAD BOLTS REMOVAL

Use special tool cylinder head bolt wrench
(MB991654) to loosen the cylinder head bolts in two
or three steps in the order of the numbers shown in
the illustration. If the cylinder head bolts cannot be
pulled out due to the washer being trapped in the
valve spring, raise the bolt slightly, then remove it
while holding it by using a magnet.

Do not allow any foreign materials get into the
coolant passages, oil passages and cylinder.
1. Degrease the cylinder head gasket mounting

surface.

2. Assemble to the cylinder block so the cylinder

head gasket identification mark of "381" is at the
top surface and on the exhaust side.

>>B<< CYLINDER HEAD BOLTS INSTALLATION

1. Check that the nominal length of each cylinder

head bolt meets the limit. If it exceeds the limit,
replace the bolts with a new one.

Limit (A): 99.4 mm

2. Apply a small amount of engine oil to the thread of

the bolts and to the washers.

3. Use special tool cylinder head bolt wrench

(MB991654) to tighten the cylinder head bolts in
the following procedures.
(1) Tighten the bolts to 78

±

2 N

⋅

m in the order

shown.

(2) Loosen the bolts fully in the reverse sequence

to that shown.

(3) Tighten the bolts to 20

±

2 N

⋅

m in the order

shown.
