5.10.1. Mechanism of a tension of a driving chain

GENERAL INFORMATION

Prevention

At installation of a kolpachkovy nut of the mechanism of a tension it is necessary to use a new sealing ring.


Installation of a new chain

At installation of a new chain support chain branches in constantly tense situation.

And
– a new driving chain;
In – an old driving chain;
With – an asterisk of the camshaft operating final valves


Mechanism of a tension of a driving chain

A–stopper;

B–sealing ring;

C–pin;

D–spring;

E–bracket;

F–plunzher;

G–case;

H–sealing ring

Removal

Unscrewing of a stopper of the mechanism of a tension of a driving chain

 


Vyvinchivaniye assembled mechanism of a tension of a driving chain

 


PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Unscrew bolts and remove a krylchatka of the fan of a radiator.
3. Remove an auxiliary driving belt.
4. At existence remove the air pump.
5. Close the generator pure rags.
6. On one turn unscrew a stopper of the mechanism of a tension of a driving chain (see fig. Unscrewing of a stopper of the mechanism of a tension of a driving chain).
7. Unscrew assembled the mechanism of a tension of a driving chain from the engine (see Vyvinchivaniye's fig. assembled the mechanism of a tension of a driving chain).
8. Unscrew a cover and take from the case of the mechanism of a tension a pin and a spring.
9. Squeeze out from the case of the mechanism of a tension a plunzher with a bracket.

Check

PERFORMANCE ORDER
1. Clear details of the mechanism of a tension of a driving chain and check lack of wear on a plunzher and the case.
2. Check a condition of a bracket and a spring of the mechanism of a tension and, if necessary, replace them.

Installation

PERFORMANCE ORDER
1. Screw in the case of the mechanism of a tension of a driving chain with a new sealing ring in the block of cylinders and tighten the demanded moment.
2. Insert a plunzher with a bracket into the case of the mechanism of a tension, then establish a spring and a pin.
3. Screw in in the case of the mechanism of a tension a stopper with a new sealing ring and tighten it the demanded moment.
4. At existence establish the air pump.
5. Establish an auxiliary driving belt.
6. Establish a krylchatka of the fan of a radiator.
7. Connect a weight wire to the accumulator.
