NOTE Lubricate the screws with engine oil.
Recover the clearance between the timing system gears by tur-
ning the flywheel in the opposite direction of the engine rota-
tion direction and subsequently turning it in the engine rotation
direction until the dial gauge shows the specific value.
Check the previously described conditions.

Turn the crankshaft bringing cylinder piston no. 1 in compres-
sion stage to TDC; turn the flywheel by approximately 1/4 turn
in the opposite direction to the normal direction of rotation.
Turn the flywheel again according to normal direction of rota-
tion (anti-clockwise) until the hole marked with the three not-
ches can be seen through the inspection hole under the fly-
wheel housing (4).
NOTE Iftheengineflywheeldoesnothave3 notches,
to identify the reference hole simply: turn the
flywheel in the opposite direction to the opera-
ting direction until you reach the position mar-
ked with 2 notches (54˚ before cyl. 1 T.D.C.);
continue rotating in the engine operating direc-
tion for 4 holes (remember that each hole cor-
responds to a flywheel rotation of 6˚).
