2.1.11. Natyazhitel of a belt of a drive of hinged unitsStatic check
Natyazhitel of a belt of a drive of hinged units can be checked statically, operating how it is described below.
1. Disconnect a belt of a drive of hinged units in a zone of a natyazhitel of a belt.
2. Using the special tool, move a natyazhitel of a belt from its free situation at full capacity the piston and back to free situation to make sure that there is no jamming and a prikhvatyvaniye, and make sure that the spring of a natyazhitel of a belt is in a tension.
3. Turn a pulley of a natyazhitel of a belt of a drive of hinged units and check it on existence of damages and freedom of rotation and correctness of adjustment. If necessary establish a new natyazhitel.
4. Examine a zone, surrounding a natyazhitel of a belt of a drive of hinged units on availability of greasing or other pollution. Before installation of a new natyazhitel eliminate all leakages. If the natyazhitel of a belt is polluted, do not try to clear it since the mechanism of damping located inside can be damaged. If necessary establish a new natyazhitel.
5. If the natyazhitel of a belt of a drive of hinged units satisfies to aforementioned criteria, pass to dynamic check. If the natyazhitel of a belt of a drive of hinged units does not satisfy to aforementioned criteria, establish a new natyazhitel.
Dynamic check
Natyazhitel of a belt of a drive of hinged units can be checked dynamically, operating in given below sequence.
At the working engine watch moving of a natyazhitel of a belt. Natyazhitel should move to (react) at sharp acceleration of the engine or at the А/С coupling tsiklirovaniye. If moving of a natyazhitel has no constant character without acceleration of the engine or the А/С coupling tsiklirovaniye, it is possible that the pulley or a shaft is deformed or has a deviation from a standard form, or the mechanism of damping located in a natyazhitel is damaged. Excessive running start of a belt of a drive of hinged units (unequal depth of flutes in a belt of a drive of accessories) can cause excessive moving of a natyazhitel of a belt. Check a problem condition, having established a new belt of a drive of hinged units.
