3.2.6. Натяжитель chains
THE GENERAL DATA

Chains arising at work noise can be caused lacks of functioning of the tension device. Disassemble and check up it. If necessary replace the tension device in the complete set.

Натяжитель chains (244) will screw on the right side in a head of the block of cylinders. Through an aperture in a head of the block of cylinders in натяжитель chains engine oil moves under pressure.


The chain stretches under action of force of a spring of compression (230) and pressure of oil in натяжителе. Pressure of a clip of a finger (233) on the tyre of management (215) is supported to constants by means of the return valve (227/228) and the valve of restriction of pressure (227/231), i.e. Does not depend on pressure of oil in the engine.

Removal
PERFORMANCE ORDER
Unscrew натяжитель chains for шестигранную a head (235) of a head of the block of cylinders.

The control

PERFORMANCE ORDER
1. Place натяжитель chains with a press finger in engine oil SAE 10. Oil level should be a little above a side шестигранной heads натяжителя. Press 7–10 times on press a finger a press.
2. After filling with oil натяжитель it should be compressed slowly, in regular intervals and with the big power effort. Otherwise replace it.

Installation

The prevention

Mount натяжитель chains only in the condition filled with oil.

PERFORMANCE ORDER
Establish натяжитель chains with use of a new sealing lining and tighten bolts of fastening with the moment 80 Н.м. Thus press the finger should adjoin to a ledge of a sled of a tension.
