(No 3824591) by hand and simultaneously pressing a timing pin (Fig. 5.17). When the pin
slides into the camshaft hole, the cylinder piston has reached the top dead center (TDC).

IMPORTANT: When the piston is positioned in its TDC remove the pin so as not to cause damage
to the pin or engine.
5. Check and adjust (step 1), if necessary, the valve lash as shown in Fig. 5.18. Use a screw
driver, a wrench and a filler gauge. The value of the valve lash should be as follows:
•
Intake valve (I): 0.30 [mm],
•
Exhaust valve (E): 0.61 [mm].
Tighten the adjusting nut up to the torque of 24 [Nm] and check the lash again.
