TIMING ADJUSTMENT

CAUTION:

It is essential to degrease the end of the crankshaft, the bore of the crankshaft sprocket and the bear-
ing faces of the drive belt pulley to prevent any slip between the timing and the crankshaft which
would risk destroying the engine.

and cylinder head holes.

3.

Check that the mark on the high pressure pump pulley (2) has
shifted one tooth to the right of vertical axle.

4.

Turn crankshaft to set Tool KV113B0130 (Mot. 1489) (the crank-
shaft groove (1) must be facing upwards).

Inspection and Adjustment

INFOID:0000000010282055

INSPECTION

1.

Place the valves of the cylinder concerned at the “end of
exhaust - beginning of intake” position and inspect the clearance
(X). 
NOTE:
Dimension (Y) corresponds to the tappet thickness sizes (there
are 25 sizes at the service parts). 

2.

Compare the values recorded with the values specified, then
replace the tappets which are not within tolerance.

ADJUSTMENT

1.

The camshaft must be removed to replace the tappets.
Determining dimension (Y).

2.

Set up the following assembly using dial gauge stand
[KV113B0050 (Mot. 252-01) (commercial service tool) or equiva-
lent tool] and dial gauge, then calibrate the gauge.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to 

MA-59, "Fluids and Lubricants"

.

• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-

ing engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the

specified level, if necessary.
