Fingers (and a bulb using if it is necessary) you walk all length of a belt, on existence of cracks and stratifications feeling. Also you check whether is available on a belt of pathetic qualities and sapolirowannych to gloss of the land plots. The belt has to be seen by both parties that its need of perekrutschiwanija thinks for check of a condition of the back. At the same time are convinced of lack of a rust, cracks and agnails on glasses. On a working surface of a belt existence not of deep vertical cracks is allowed. If these cracks of edge very deeply not about hinauslangen borders to replace a belt there is no need.

Check of a belt of an incentive of auxiliary devices

A — the New belt
B — sale of walls - edges (on a new belt their trapezeidalnyje) are sharp
With — Ogolenije of velveteen
D — a crack on thinking out a belt
Basis rubber E — Otslojenije
F — sale of external velveteen

G — breakage of side velveteen
H — a crack through edges
J — damage of edges
K — a crack of the separated edges
L — pollution or jamming of stones between edges
M — Wyrywanije of rubber at edges


Tension of a ridge belt is automatically made. It is necessary to check a condition of a belt periodically and to replace at detection of defects, a belt.

Tension of a belt is automatically carried out by natjaschitelem and check does not need.

 EXECUTION ORDER

1. Exclude the motor, establish transmission in neutral situation. Lift and install the car on shelves.
2. Note from chalk a belt on quite visible place.
3. From prowernite head the motor for glass of a bent shaft in the direction of Drehens, i.e. to the right side in such a way that Kreidmarkierung was noticeable. At the same time you look through the land plot behind the land plot to belts.


belt establishing priwodnoj, you establish it on glasses correctly - it strictly has to be after the center of glass (even short-term work of mistakenly certain belt can lead to its damage)


Tension of a belt can be checked by means of a firm pridavlivaniye for it from a thumb and definition of a step of its deflection. You measure deflection size from a ruler. If removal forms glasses 180 up to 280 mm between centers, then the size of a deflection of 6 mm has to equate itself. If removal is glasses in borders between 300 and 400 mm between centers, the deflection has to be 13 mm.

In the presence of one or some of the specified damages of klinowoj the belt needs to be replaced with new by all means.
