The camshaft gear of the timing mechanism is driven from the camshaft belt drive by a toothed belt, which simultaneously drives the coolant pump.
The CR POWER timing belt is marked 137 STD 8–19 (137 belt teeth, STD = brand, 8 = tooth pitch, 19 = tooth width). The rubber belt with wire reinforcement is constantly tensioned by a sprung roller.
When installing the timing belt, it is necessary to set the piston of the first cylinder at the top dead center, and the mark on the driving gear of the camshaft of the timing mechanism should be opposite the mark on the front cover. At the same time, the driven gear of the timing mechanism should be fixed on the camshaft so that the mark on it is opposite the mark on the boss of the head (see Fig. Marks for mutual installation of timing gears).
The leading gear of the gas distribution mechanism is mounted on the cylindrical surface of the end of the camshaft. A belt drive pulley with radial grooves for the alternator drive belt and other auxiliary equipment is attached to it with four M8 bolts.
The timing belt is covered with a plastic casing consisting of three parts. Before dismantling the timing belt, it is necessary (if it is still in use) indicate the direction of its movement. The timing gears, toothed belt, casings and other parts are shown in Fig. Timing gear casings, cylinder head seals and cylinder head cover.
