4.10.1. Mechanism of a tension of a driving chain

 Removal
Prevention

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

Mechanism of a tension of a driving chain
1–kolpachkovy nut;
2–sealing ring;
3–spring;
4–bracket; 		5–plunzher;
6–a ring with a carving;
7–case

The direction of extraction of a plunzher (1) with a bracket (2) from the case (3) mechanisms of a tension of a driving chain

 

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Open a cowl and establish it in vertical situation.
3. From the right forward party of the engine unscrew a kolpachkovy nut and take a spring and a sealing ring (see fig. Mechanism of a tension of a driving chain).
4. Using a face key, unscrew a ring with a carving and take the case of the mechanism of a tension.
5. Take from the case a plunzher with a bracket (see fig. The direction of extraction of a plunzher with a bracket from the case of the mechanism of a tension of a driving chain).

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. Establish the case of the mechanism of a tension in a cover of a driving chain and fix it a ring with a carving, having tightened it the demanded moment.
2. Establish a plunzher with a bracket in the case of the mechanism of a tension against the stop brackets in a fillet in the case of the mechanism of a tension.
3. Establish a spring and screw a kolpachkovy nut with a new sealing ring and tighten it the demanded moment.
4. Connect a weight wire to the accumulator.
