BOOT OF THE MECHANISM OF THE TENSION

Removal

PERFORMANCE ORDER
1. Remove a head of the block of cylinders.
2. Uncover a driving chain.
3. Unscrew the mechanism of a tension of a driving chain.
4. Remove a boot of the mechanism of a tension.

Check

PERFORMANCE ORDER
1. Check a condition of a boot of the mechanism of a tension on lack of wear and damages and if necessary, replace it.

Installation

PERFORMANCE ORDER
1. Establish a boot of the mechanism of a tension.
2. Screw in the mechanism of a tension of a driving chain.
3. Establish a cover of a driving chain.

TOP USPOKOITEL OF THE CHAIN

Removal

Elements of the top uspokoitel of a chain
1–top adjusting pin;

2–bottom adjusting pin;

3–top uspokoitel of a driving chain


Use of an inertial hammer with an adapter for extraction of the top adjusting pin of an uspokoitel of a chain

PERFORMANCE ORDER
1. Remove a camshaft asterisk.
2. Screw in an additional bolt in one of adjusting pins of the top uspokoitel of a chain and, using an inertial hammer with an adapter, for a head of an additional bolt take an adjusting pin of an uspokoitel of a chain (see fig. Elements of the top uspokoitel of a chain, Use an inertial hammer with an adapter for extraction of the top adjusting pin of an uspokoitel of a chain).
3. Similarly take the second adjusting pin.
4. Remove the top uspokoitel of a chain from a head of the block of cylinders.

Check

PERFORMANCE ORDER
1. Check a condition of a boot of the mechanism of a tension on lack of wear and damages and if necessary, replace it.

Installation

PERFORMANCE ORDER
