Maintenance task. Valve clearance inspection
The rocker cover must be dismounted to check the valve clearance. This operation must be
carried out when the engine is cold.

Inspection
1.
Inspect the valve clearance in the injection sequence. To check, turn the crankshaft by the
specified crank angle in the normal direction to bring the piston to the top dead center of the
compression stroke.

2.
The TDC of the compression stroke can be obtained by
aligning the TDC mark on the crankshaft pulley (1) with the
mark on the gear case (2).
3.
First align the TDC mark for the No.1 cylinder. Confirm that
the valves do not move up and down when the crankshaft
is turned about 20º in normal direction of rotation and in
reverse direction. If the rocker arms move, No. 1 piston is
at TDC on the intake or exhaust stroke. In such a case,
turn the crankshaft 360º in the direction of engine
rotation again. No.1 piston is now at TDC on the
compression stroke.
4.
Loosen the lock nut for the adjusting screw. With a
feeler gauge inserted between the rocker arm and
valve cap, adjust the valve clearance by turning the
adjusting screw.
5.
After adjusting the clearance, tighten the lock nut.
Inspect the clearance again and make sure that it is correct.
6.
Turn the crankshaft 240º or 180º clockwise, according to your engine model (see table 8.
Injection sequence), from TDC of the No.1 cylinder, to set the No.2-cylinder TDC. Repeat from
step 1 to step 6. And the same procedure for No.3 and 4 cylinders.
7.
After the valve clearance on the valves for all cylinders has been adjusted, turn the crankshaft
two or three times and make sure the valve clearance is correct.
