II - OPERATION FOR REMOVAL OF PART
CONCERNED
1 - Adjusting the timing
aTurn the crankshaft clockwise (timing end). Stop a
half-tooth before the crankshaft sprocket mark is
lined up with the fixed marking.a
aInsert the TDC setting pin (Mot. 1054).
aTurn the crankshaft clockwise until it is stopped.

mark on the outside of the timing belt.
Procedure for tensioning timing belt
aRemove:
-the TDC setting pin,
-the tension wheel pin.aTurn the tensioning roller eccentric anti-clockwise,
using a 6 mm Allen key, to bring the adjustable in-
dex level with the fixed index.
aTorque tighten the tensioning roller nut (24 N.m).
aRotate the crankshaft through six revolutions in a
clockwise direction (timing end).
