12. At the forthcoming repeated installation of a gear belt замаркируйте it. Thus it is necessary to put on a belt with a chertilka an arrow of the direction of rotation. The engine rotates clockwise.
13. Unscrew obodny a roller.
14. Remove a gear belt. After that cogwheels do not turn.

Prevention

Before removal once again check, whether the label on a camshaft wheel coincides with edge of a head of cylinders, if necessary modify.

For this purpose turn a cranked shaft before coincidence of a label (1) on a cogwheel of a camshaft (2) with a label on a face-to-face payment. Then turn a wheel of a cranked shaft on 1/4 turns (90 °) to the left or to the right. The label should be turned now to the left or to the right.

Installation
Prevention

Gear belt do not bend and do not turn off. Surely replace the polluted, damaged or worn-out belts. Check uniformity and ease of a course of a tension roller.

Tension

PERFORMANCE ORDER
1. Weaken a bolt of a tension roller so that the roller could move to a gear belt under effort of a spring.
2. Turn a cranked shaft on two turns clockwise before coincidence of labels on a camshaft and on a face-to-face payment. Be once again convinced that all labels coincide.
3. Tighten a bolt of a tension roller with effort of 50 N of m.
4. Turn a cranked shaft on two turns in the direction of rotation of the engine and once again check adjustment.
