FORM-IN-PLACE-GASKET
FIPG is used for several members of this engine. With this gasket, caution is required to the application
amount, application procedure and state of the application surface so that the performance is sufficiently
attained.
If sufficient gasket is not applied, leaks could occur, and if too much is applied, the gasket could protrude
and plug or restrict the oil and water flow passage. Thus, to prevent leaks from the joined sections,
it is absolutely necessary to evenly apply the correct amount.
The FIPG used for the engine parts reacts with moisture in the air and hardens so use it for the normal
metal flange parts.
DISASSEMBLY
The parts assembled with FIPG can be easily disassembled without special means. However, in some
cases, the sealant on the seams must be broken by lightly tapping with a wood hammer or similar tool.
A smooth and thin gasket scraper can be lightly tapped into the seams but in this case, take care not
to damage the seams.
The special tool oil pan remover (MD998727) is set for this purpose.
WASHING THE GASKET SURFACE
Completely remove all matters adhered on the gasket surfaces with a gasket scraper or wire brush.
Confirm that the FIPG application surface is smooth. There must be no grease or foreign matter on
the gasket surface.
Always remove the old FIPG that has entered the mounting holes and screw holes.
APPLICATION PROCEDURES
Apply an even coat of FIPG within the predetermined radius. Completely cover the areas around the
mounting holes. The FIPG can be wiped off if it has not hardened. Install at the set position while the
FIPG is still wet (within 15 minutes). When installing, maker sure that the FIPG does not get on areas
other than the required areas. After installing, do not subject the application areas to oil or water or
start the engine until the FIPG has sufficiently hardened (approx. one hour). The FIPG application procedures
differ according to the member, so follow the procedures given in this manual and apply the FIPG.

4. Install the rocker cover onto the cylinder head before
the form-in-place gasket hardens.
"EACRANKSHAFT SPROCKET B INSTALLATION
Clean the crankshaft sprocket B installation surface before
degreasing the crankshaft sprocket B.
NOTE
Always degrease the surface to prevent a drop in the frictional
coefficient at the pressing section caused by the adherence
of oil.
"FASPACER INSTALLATION
1. Apply a slight amount of oil on the outer periphery of
the spacer (oil seal contact section).
2. Insert the spacer from the chamfered side as shown in
the illustration.
Caution
Reversed insertion of the spacer can cause damage
to the oil seal lip.
"GACOUNTER BALANCE SHAFT SPROCKET

3. Confirm that the tensioner B centre and bolt centre are
positioned as shown in the illustration.
4. Apply tension on the timing belt by lifting tensioner B
in the direction of the arrow with a finger, and tension
the tension side until it is “tight”. Fix tensioner B in this
state by tightening the bolt.
NOTE
Make sure that the tensioner B shaft does not rotate
when tightening the bolt. If the shaft rotates, the timing
belt becomes too tense.
5. Connect the special tool (MB991704) to MUT-IIand the
battery.
6. Connect the special tool (MB991668) to MUT-II.
7. Rotate the crankshaft clockwise two turns, and align each
timing mark.
8. Select “Belt Tension Measurement” from the MUT-IImenu
screen.
9. Separate the special tool (MB991668) 10 to 20 mm from
the centre back between the sprockets (shown with an
arrow), and hold so that it is vertical (inclination within
±15_) in respect to the belt.
10. Lightly tap the section shown with an arrow with fingers,
and measure the belt vibration frequency. If the results
are deviated from the standard value, loosen the bolt,
tension the belt again, and then measure the vibration
frequency again. Repeat this step until the standard value
is attained. Tighten the bolt when the standard value
is attained.

2. Align the timing mark of the intake side camshaft sprocket
to the timing mark on the rocker cover.
NOTE
Even when the sprocket and rocker cover timing marks
are aligned, the intake camshaft will rotate slightly in the
clockwise direction by the force of the valve spring and
will stabilize.
3. Shift and set the crankshaft sprocket timing mark by one
tooth in the counterclockwise direction in the same manner
as the exhaust side camshaft sprocket.
4. Align the oil pump sprocket timing marks.
5. When aligning the oil pump sprocket timing marks, remove
the cylinder block plug, and insert an 8 mm shaft diameter
Phillips driver into the plug hole, and confirm that the
driver shaft can be inserted by 60 mm or more. Do not
remove the Phillips driver until the timing belt has been
attached. If the driver shaft contacts the silent shaft and
only enters 20 to 25 mm, rotate the sprocket once, align
the timing marks again, and then confirm that the Phillips
driver can be inserted by 60 mm or more.
6. Remove the Phillips driver, and set the oil pump sprocket
at a position returned by one tooth in the counterclockwise
direction.
7. Attach the timing belt to the exhaust side camshaft
sprocket, and fix with a paper clip at the position shown
in the illustration.

counterclockwise direction. Attach the belt at a position
where the timing mark is deviated by one tooth in the
counterclockwise direction, and then fix with a paper clip.
NOTE
Even if the belt is attached at a position deviated by
one tooth, the intake camshaft will rotate slightly in the
clockwise direction by the force of the valve spring and
will stabilize.
9. Rotate the exhaust side camshaft sprocket in the
clockwise direction, and confirm that the intake side
camshaft sprocket’s timing marks are aligned when the
timing marks are aligned.
10. Attach the timing belt in the order of the idler pulley,
oil pump sprocket and crankshaft sprocket.
NOTE
Attach the timing belt so that it is not deflected.
11. Attach the timing belt to the tensioner pulley.
NOTE
The timing belt can be attached easily to the tensioner
pulley by rotating the intake side camshaft sprocket slightly
in the counterclockwise direction.
12. Rotate the crankshaft sprocket slightly in the clockwise
direction, and remove the timing belt deflection on the
idler pulley side.

14. Using the special tool, rotate the tensioner pulley in the
counterclockwise direction to tense the timing belt, and
then fix by temporarily tightening the tensioner fixing bolt.
NOTE
Remove the deflection of the timing belt between the
intake side and exhaust side camshafts.
15. Rotate the crankshaft in the clockwise direction, and set
the timing mark at the No. 1 cylinder compression top
dead centre.
16. Set the special tool, and screw it in until the wire inserted
when the auto tensioner was installed slightly moves.
17. Loosen the tensioner pulley fixing bolt.
Caution
The timing belt will loosen at this time due to the
rotation of the intake and exhaust camshafts, so make
sure that the timing belt does not deviate.
18. Rotate the special tool and torque wrench in the
counterclockwise direction to remove the timing belt
deflection.
19. From that state, return to the position where the torque
wrench scale reads 3.5 N•m, and then tighten the fixing
bolt.
20. Remove the special tool installed in step 16.
21. Rotate the crankshaft two rotations in the clockwise
direction, and let stand for approx. 15 minutes.
22. Confirm whether the wire inserted when the auto tensioner
was installed can be pulled out easily. If it can be removed
easily, the belt tension is appropriate, so remove the wire.
If the auto tensioner rod’s protrusion amount is at the
standard value, the tension is appropriate.
Standard value: 3.8 - 4.5 mm
23. If the wire cannot be pulled out easily, repeat steps 16
to 21, and tense the belt to the appropriate tension.
Caution
When the crankshaft bolt has been rotated in the
counterclockwise direction, always check the crank-
shaft bolt’s tightening torque. If loosen, re-tighten.
