Removing
When installing a new chain, keep both branches of the chain taut at all times.
Unscrewing the cap nut from the drive chain tensioner housing
Removing the spring and o-ring from the drive chain tensioner
Drive chain tensioner
1 - cap nut; 2 - sealing ring; 3 - spring; 4 - bracket; 5 - plunger; 6 - body
The direction of extraction of the plunger with the bracket from the housing of the drive chain tensioner
1 - body; 2 - plunger; 3 - bracket
1. Remove the ground wire from the battery.
2. Remove the auxiliary drive belt.
3. To improve access to the drive chain tensioner, remove the alternator.
4. On the right front side of the engine, unscrew the cap nut from the drive chain tensioner housing and remove the spring and o-ring (see fig. Unscrewing the cap nut from the drive chain tensioner housing, Removing the spring and O-ring from the drive chain tensioner).
Attention! When unscrewing the cap nut, be careful as the nut is subjected to a highly compressed spring.
5. Unscrew the drive chain tensioner housing from the engine block (see fig. Drive chain tensioner).
6. Remove the plunger with the bracket from the drive chain tensioner housing (see fig. The direction of extraction of the plunger with the bracket from the housing of the drive chain tensioner).
Replacement
1. Clean the parts of the drive chain tensioner and check for wear on the plunger and housing.
2. Check the condition of the tensioner caliper and spring and replace if necessary.
Installation
The location of the plunger in the housing of the drive chain tensioner
1 - the position of the plunger during installation;
2 - the direction of the plunger removal from the body
1. Screw the drive chain tensioner housing into the cylinder block and tighten to the correct torque.
2. Insert the plunger with the bracket into the body of the drive belt tensioner until the bracket stops against the shoulder of the inner cavity of the body (see fig. The location of the plunger in the housing of the drive chain tensioner).
3. Insert the spring into the housing, install a new sealing ring on the cap nut and, overcoming the resistance of the spring, screw on the cap nut and tighten it to the required torque.
4. Install the generator.
5. Install the auxiliary drive belt.
6. Connect ground wire to battery.
