Removing
1. Turn the tensioner with the Torx head counterclockwise, thus loosening the V-belt.
2. Lock the tensioner in this position. To do this, insert a pin through the holes in the front part and tensioner housing. The finger can be made independently from a bar. Dimensions: length approx. 50 mm, diameter = 4 mm.
3. Remove the V-belt.
Attention! When carrying out further work on the engine or the distributor housing cover, the tensioner must be loosened.
Examination
1. Check the pulley grooves for damage and dirt, clean or replace the pulley if necessary. At the same time, pay attention to the wear of the tensioner supports and to the defects of the pulley.
2. If the supports are worn, the tensioner must be replaced.
3. A V-belt with dirt inclusions between the ribs, weakened ribs, in the presence of fraying, transverse cracks and breaks in the ribs must be replaced, refer also to Chapter Current service.
Installation
1. Put on the V-belt, starting with the tension roller.
2. Slightly turn the tensioner counterclockwise, thus loosening the locking pin.
3. Remove the lock pin.
4. Slowly turn the front part of the tensioner clockwise with a wrench and thus tension the V-belt.
Attention! Tension the belt slowly, do not release the tensioner.
