1, internal bearing aging damage. Seriously causing the tensioning wheel to completely fail to work.

2. Tensioner wheel damage leads to timing tooth hopping, ignition and air distribution time disorder, engine jitter ignition difficulty, etc., and deformation of starting handle valve top.

3. The tensioner of the generator belt is damaged, the vehicle generator cannot work normally, and the steering power does not work.

The following is the tensioner wheel extension information:

1. The tensioning wheel plays a guiding and tensioning role on the timing belt or chain of the engine.

2. Under the working condition of timing belt or timing chain, the camshaft drives the positive valve for time to switch, and completes the four processes of inlet, compression, work and exhaust with the piston.
